I do not own the rights to anything Disney.
Everything Comes to an End
So you're probably wondering where I've been. Well, after writing the last chapter, I got an idea for a Tangled x Frozen crossover that has Hans redeem himself, and is a retelling of Hansel and Gretel. It's called 'A Baker's Dozen' and is finished, so go check it out if you're interested. Once that was done, I was going to finish this up since I finally had Corona off my brain, but then I decided to do Nano. I finished Nano, and then started to focus on original stories. I have tried so many times since then to get back to this story, but I couldn't write more than a few sentences. Now I have Descendants on the brain and want to finish the fic that I started, but not before I didn't do something to wrap this story up. Below, is an outline of the rest of the story. There are also written parts, dialogue exchanges, and my notes regarding certain reveals and twists.
I'd like to thank everyone who's read, reviewed, favorited, and followed this story. Sorry it's been so long, but at least you know how it ends.
Sidney flinched at the sound of the twig breaking behind her. She had found a spot near the ruins of the bridge to sit at and contemplate her woes and her next course of action. Her broken arm was clutched by her side in a makeshift sling out of the jacket she had worn underneath her armor in order to keep out the cold from the metal touching her skin. Said armor was currently strewn about her, falling from wherever she had dropped it. She may not have known how to heal her arm, but she could at least use magic to get the clunky armor off now that she no longer needed it.
"I must say, this a change… is little Sidney Yates afraid of the big, bad Hook?"
Sidney turned her body and saw Hook standing behind her with a devilish gleam in his eye. She gulped nervously; she had never been this close to him, or any of the villains really. Gaston was probably the closest she had ever been to a villain, and that was a few hours ago when he was trying to kill her.
Until Lindsey stopped him. Not herself, who had been trained to do so, but her sister who had done everything in her power to run from confrontation.
"I'm, not a-afraid," she stuttered, which seemed to please Hook.
A smile played across his face and he stepped closer to her. "Sounds like you're afraid to me."
"Oy, could you knock it off with the theatrics?" said Hades. Sidney didn't know when he appeared or where he came from. Just that she was now in the presence of two powerful villains, had a broken arm, and was nowhere near in any condition to fight them off.
"But Hades, after all these years and we're finally face to face with the great and powerful Sidney Yates, who once swore that she would capture and lock up all those who stood against her. And yet, here she is, doing no such thing. Let's take a second and enjoy this moment."
Hades waved his hand about in the air. "Fine, whatever. Don't take too long, I do have a schedule to keep, ya know."
"Believe me, I know. Just let me take a second to relish this momentous occasion which has been so long in coming. I'd like to remember it till my dying days," sighed Hook with a smirk on his face, taking in the moment.
"You done?" asked Hades.
"Oh no, I've just gotten started," replied Hook, sending a shiver down Sidney's spine while he twirled his mustache around with his hook.
"Do tell," prompted Hades, who didn't have a mustache to twirl, but did have a rather sinister smirk forming on his face.
Hook took a step forward towards Sidney. "As recent events have revealed, you are no longer the little darling of your precious heroes, your sister is. Which means you belong with us."
"Never!" cried Sidney as she jumped to her feet, while doing her best to ignore the ache in her broken arm. "I'll never join the likes of you!"
"Oh really?" sneered Hook. "Would you like to do the honors, Hades?"
"Do you even have to ask?" Not even bothering to wait for a response, Hades snapped his fingers causing a figure to appear between the trio. He had a black eye, and was bound and gagged with strips of smoke. Dirt and sweat streaked his body, but he was at least alive. Which was more than could be said of some of his men.
Sidney wasted no time to rush to Roland's side, using her one good arm to try and pull his smoky gag away too little to no avail. Her hand did nothing more than disperse the smoke for a few seconds, only for it to reform a few seconds later. She desperately continued to claw at it, but had no success.
"Isn't she supposed to be the smart one?" asked Hades to Hook, while watching Sidney struggle futilely against Roland's gag and his restraints.
Hook shrugged, enjoying the spectacle. "Hopefully the pain in her arm is clouding her brain."
Hades offers Sidney a deal, he'll return Roland to the heroes if she agrees to join the villains. Hook adds in that she actually has to try, no wimping out or secretly helping the heroes. Roland begs her not to, but she agrees, and swears a magical oath with Hades. At one point, there's the following exchange:
Hook: And we promise not a single hair on his head will come to harm
Sidney: Do you really think I'm stupid enough to fall for that?
Hades: What do you know, she is the smart one after all
Hades then vanishes with Roland, while Hook is left with Sidney . Hook confesses that if he had a choice, he'd choose Lindsey over Sidney. After all, it was Lindsey who managed to finish off Gaston, not Sidney. If it wasn't for Lindsey, Sidney would be dead. Sidney says nothing, continuing to have the worst day ever.
Meanwhile, Merlin tries to get to know Lindsey who's still in a mood. She insults the Blue Fairy (due to her change in hair color), and Merlin takes offense. Merlin points out that Sidney never acted like this, and Lindsey counters that Sidney isn't even there. There's a big blow up, and eventually Merlin and Lindsey agree to start over. Lindsey says that if Merlin really wants to be her friend, he'll tell her the entire prophecy since nobody else would. He reluctantly agrees and tells her the following:
Two sisters from a foreign land,
Shall walk across a bridge hand in hand.
Their arrival will signal the coming of a great war,
The likes of which has never been seen before.
Heroes and villains will make up each side,
Many will live while others will die.
To each side a sister will lead and fight,
Into the final battle, dark versus light.
With the Sword of Destiny, the hero will lead the way,
Against her sister and into the fray.
Only one will emerge from battle unscathed,
And shall bring about a brand new age.
Lindsey then asks where it came from, and Merlin admits that nobody truly knows, it's thought to be as old as the universe and that he originally heard it from the Blue Fairy. The two are then interrupted by the arrival of Hades and Roland, Hades dumping Roland on the palace grounds, announcing Sidney has decided to switch sides in order to save her lover boy, and has to because she swore an oath. Before he can be captured, he vanishes.
The heroes are thrown off and hurt, but still feel sympathy for Sidney since she did out of love, and some of them had even made similar choices. Lindsey is still getting looks, as if 'how dare she turn out to be the hero' all along. She wanders around the castle and finds the dungeons where some of the captured townspeople are. Among them is LeFou, and Lindsey goes to King Stefan and the other heroes, asking that the townspeople be returned. Roland objects, but Lindsey points out that Hades returned Roland unscathed (even though he did swear an oath), and he was a villain. Several others continue to object, and Lindsey points out that those captured in the dungeons aren't even the true villains, just townspeople, and the heroes are heroes, and should act like heroes. Rose supports her, and the townspeople are let go. LeFou says a tearful goodbye to Lindsey, and says that he always knew she was good, just never had an idea of how good.
Over the next several days, both girls adjust to their new living conditions. Lindsey has magic lessons with Merlin, and sword fighting with Mulan. Peter had offered, but Mulan pointed out that she actually has experience with the Sword of Destiny and Peter reluctantly agrees. Lindsey is still hesitant about using it, and Mulan confesses that you don't really use the sword, the sword uses you. As far as she knows, that's the way it's always been, that the sword acts as though it has a mind of its own, and the best you can hope for is that you don't have to use it for very long. Lindsey tracks down Phillip, and he agrees. She asks Merlin about it, and just says the sword has always been an enchanted sword, but first appeared around the time it was put in the stone, though he didn't know by who.
Meanwhile the other heroes and residents at the castle start warming up to Lindsey, and Lindsey still has doubts about being a hero. Lindsey and Peter also have some alone time and start growing close to one another. Tinkerbell is somewhat jealous and hurt, and hates that Peter is growing up. Roland stops by, apologizes, and says that he will support Lindsey and the heroes because she's part of the greater good.
At some point, a conversation takes place between Peter and Lindsey regarding her name. Peter points out that Sidney is one letter away from Lindsey and asks what the 'L' stands for. They go back and forth with lucky, loser, leader, lump, light, leak, and eventually Peter wins with love. Lindsey also notes that Sidney also spells Disney (I will admit to choosing their names based on that reason).
During this time, Sidney gets to know the villains. She refuses to take part in their planning, stating that she swore to fight which is all that she swore to do. Archimedes arrives, and Sidney convinces him to take messages to Roland and Merlin, and Archimedes reluctantly agrees. At one point Hook and Hades come up with a plan to liven her up, by throwing a party and slipping something rather strong in her drink. Sidney gets drunk for the first time in her life, and starts telling them how their stories really went back home—Hades not being the villain and being married to Persephone, Grimm's fairytales, etc… That night she bonds with them, and is later torn because she finds she likes them. Realizing that she's weakening, Maleficent orders Anastasia to show her around the town like Lindsey, and Sidney finds herself starting to question her actions in the past.
Pocahontas arrives, and joins the heroes after Lindsey explains who she is, and even acts a little bit of a fan-girl. Lindsey is still having mixed feelings about the battle, and Pocahontas tells her of a story from her tribe. Long ago, the universe came into being. There was not much, and darkness outshone the light. Then there was a great battle, and the darkness was pushed back, and light won, allowing humans to thrive. Her tribe believes that because light won once, light will win again. Lindsey confesses that it's not the heroes winning that scares her, but the villains losing.
There's more filler that I didn't quite have planned out, but I had the ending so here it is. The next few scenes contain a lot of reveals and twists, so even though this is the last chapter, if you go back and reread the chapters you'll find a lot of double meanings with certain lines and foreshadowing.
The battle starts. Roland sacrifices himself to save Lindsey. At one point Jafar corners Peter and is about to deliver a final blow, but Hook manages to take him out, though he's fatally injured. Lindsey and Peter drag him to a copse of trees, away from the battle, Tinkerbell flutters around him, with Smee by their side. Lindsey tries to comfort him, saying that Hades can just bring him back. Hook laughs in her face, stating Hades can't do that because Hook isn't part of the Disney world, instead he came over from Lindsey's world. Hook then tells them the story of he came to be.
A long time ago, for him at least, when he was barely more than a toddler, he found the bridge and came over—he was the lost child of the story they grew up with. There, the fairies met him and took him to Neverland. By now, there's confusion on their faces at the news Hook was once a boy in Neverland, but he continues. He grew up, met the love of his life, and returned to the other world and lived out a long life with his love. She died before he did, and it was time for him to return to the Disney world. Upon returning, the Blue Fairy greeted him and gave him a special charm to change his appearance.
Lindsey and Peter are still shocked, more so when he throws the charm away and reveals his true appearance—a face they recognize as Peter's albeit a much older one. Hook confirms it, and admits that even they he grew up for Lindsey, he had been in Neverland for so long, he still looked youthful in his old age. After his return, the magic of Neverland started in on him again, keeping him young and fit.
Peter has a hard time believing him, while Lindsey is reviewing all of her interactions with Hook. To prove his claim, he pulls out the locket that both Lindsey and Peter have seen him with, and opens it revealing a picture of Lindsey. He tells Peter to value the time he has with her—goodness knows his frustration with Peter stems from the fact he didn't know how lucky he was, and didn't value Lindsey like he should. He tells Lindsey to ignore what that old harpy the Blue Fairy tells her to do, and do whatever it is she wants to do, even if that means not to fight. Hook dies.
Tinkerbell stays with him as does Smee. Smee confesses he was Teddy, and returned with Peter across the bridge. He never had a family, but he had a career, and then returned with Peter to become Smee. Tinkerbell was among the fairies that first brought him to Neverland, and became his best friend. She was jealous of Wendy, and over time realized that Hook seemed rather familiar. She confronts the Blue Fairy, who's the head of the fairies, and she tells Tinkerbell to let the matter drop. Tinkerbell doesn't and eventually realizes what's going on, and Hook confesses to her, telling her she can't tell anybody, and has to act like he's still Hook to her and she complies.
Peter and Lindsey have a brief discussion. Lindsey points out this proves she and Peter make it through the battle. Peter counters by saying it could just mean that they leave right at that moment, because things could still change. Lindsey replies that she can't keep running from things, and that it's time for things to end. Peter agrees with her, and says that if she wants to fight, he'll fight by her side.
[The idea that Captain Hook and Peter Pan were the same person, popped into my head very early in the story, and I thought it would be a new interesting take on their relationship. Then came exploring Hook was so antagonistic towards Peter, besides simply playing his part. That then inspired the shipping between Peter and Lindsey. If you go back and reread the story you'll see hints of who Hook really is.]
The battle is still going on, and Peter and Lindsey emerge from their hiding place. Sidney is ready to simply get things over with, and charges at Sidney. Lindsey can feel the sword in her hand pulsing in her hand, eager to be used. Lindsey stands her ground, and raises the sword high above her head, ready to strike—only at the last second drops the sword and falls to her knees. Sidney's aim is thrown off and she misses, her momentum causes her to fall to the ground.
Sidney demands that Lindsey stand back up and fight properly. Lindsey refuses, saying she is fighting, but with words, not swords. Before she can explain, the Sword of Destiny—which had been thrown to the ground in the heat of battle—starts to shake and glow. The sisters look at each other, neither knowing what is going on.
A great burst of dark light and magic emits from the sword. Once it fades, the sword is gone and in its place is an old, skeletal looking man. Lindsey isn't impressed, but Sidney, who has studied magic for years, can sense his magic and realizes he is not simply an old man, but something much more sinister.
He thanks Lindsey, saying that he had been trapped in that sword for years, destined to helping heroes fulfill their roles. It was his job, his purpose, and he couldn't fight the magic or break his imprisonment. Then Lindsey came along and ran from him. He called out to her over the years from across the bridge, causing her fear of the bridge of the woods. She couldn't stay away forever, and eventually came back and claimed the sword that was rightfully hers when she beheaded Gaston. Afterwards, she kept throwing the sword away, but he always came back to her because he was supposed to lead her into the final battle against her sister. He continued to do his job, right up to the part when she managed to throw the sword in the heat of battle—something no hero had ever done before. All spells/curses have a way to be undone, and his was if in the heat of the battle the hero managed to resist the call of the sword and refuse to fight—which was his purpose as the sword—he'd finally be freed. With his speech over, he finally introduces him as Koschei the Deathless.
By this point, the battle has come to a standstill. Everybody had seen the light and smoke caused by Koschei breaking out of his prison and heard his spiel. There are some who have heard of him, and Maleficent at one point calls him 'Uncle' (in an earlier chapter she had revealed to Sidney some of her origins—being the daughter of the Slavic Dark God Chernabog and one of the fey, who was cast out for having relations with Chernabog).
Koschei then turns into a gigantic dragon and starts attacking both villains and heroes alike, wanting to see the world destroyed—partly out of revenge for his imprisonment, and partly because it would mean no more heroes and no more villains which would mean no more battles. Nothing would be left but silence.
Realizing that they have no other option, both villains and heroes fight against him, but to no avail. Their attacks aren't making a dent in the frail figure, and instead he just gets stronger. He then laughs and boasts about being Koschei the Deathless—nobody can kill Koschei but Koschei.
Sidney yells at Lindsey for letting him free, and Lindsey yells back that it was stupid prophecy in the first place and they wouldn't be here if people had just ignored it. Peter remembers that Sidney had once talked about some sort of spell to use on Lindsey, back when everybody still thought Sidney was still the hero. Sidney admits there was an entrapment spell the Blue Fairy had taught her, but it requires a lot of power and magic and she doesn't know if she's powerful to pull it off. It might even take her life, but she agrees to try it anyway.
Lindsey and Peter get the others to shield Sidney as she attempts the spell. It appears to be working ,with Koschei weakening. However, he's more powerful, and causes the spell to backfire on Sidney, throwing his magic back on her along with his own. This causes an explosion, and both Sidney and Koschei disappear.
Lindsey is distraught by her sister's disappearance, while the others look at each other, silently asking, is it really over? The Cheshire Cat suddenly appears on top of Lindsey's head, and asks her what the matter is.
Cheshire Cat: What's wrong Not-Lost Girl?
Lindsey: What's wrong? What's wrong? What's wrong is the fact that my sister just disappeared into thin air after fighting some ancient demon thing and is most likely dead and it's all my fault!
Cheshire Cat: Hmm… but I just saw your sister a few minutes too. You too, Not-Lost Girl.
Lindsey: Yeah, because you just came from my past!
Cheshire Cat: I don't think so… you were pretty sure it was the future. Even told me to come here. Of course, if you don't want to go…
Lindsey agrees to go with him, and before anybody can stop her (none of them even knew that he could disappear with a person) she's gone.
She was falling. She was everywhere and nowhere at once. She saw glimpses of light and scenes before her eyes. There were there one second and gone the next, before she could make much sense of it.
She was the drop of sun on a single flower that could heal.
She was the seed which would grow up to be wise and magical willow tree.
She was the water surrounding an island that would fly into the air and be home to a boy that would refuse to grow up, for a while at least.
She was the second star to the right, the one that led the boy home and caused a firefly to fall in love.
She was the spring on the island, causing time to stand still, healing all woes, and giving rise to the tree the fairies would call home.
She was the spark of magic that fell into a young baby, giving her the gift of ice magic.
She was the arcade in which the games were alive.
She was the falling star that a little girl on an island saw and made a wish for a best friend, an angel.
Sidney Yates was falling and falling through all of time and space. She was anywhere and any when all at once. And just when she thought there was nothing but darkness and emptiness, there was a bright light. And suddenly, she was falling no more.
[I would like to point out that I had this ending in mind before the Series 7 Dr. Who finale. Take that Moffat. The idea was that the backlash from Sidney's entrapment/imprisonment spell combined with Koschei's magic was too much, sending both of them through time and space. Koschei the Deathless comes from Slavic mythology (as does Chernabog). He's called the Deathless because his soul is separated from his body inside a needle, which is in an egg, that's in a duck, which is in a hare, that's in a chest, that's buried under a green oak tree, that's on an island (basically the inspiration for horcruxes in Harry Potter). In this story he's the Deathless because the only thing that can kill him is himself. Therefore the trip through space and time didn't splinter him like it did Sidney. Sidney and her magic was sent throughout all of time and space, fixing all those little plot holes you noticed in the movies, or in some cases setting off the chain of events for the movie to occur (like Tangled with the flower). Before this scene, there would have been more tidbits dropped here and there about his existence, so the reveal would have made some sort of sense like the other twists.]
Sidney wakes up and realizes that she's in a barren landscape, with Koschei still. She's dying though, the backlash from the magic explosion and falling through all of time and space. Then Lindsey arrives with the Cheshire Cat who then promptly leaves. Koschei takes in the scene and lets out a mighty roar, attracting the attention of Koschei—the younger version, who's curious about the pretender. Lindsey pulls Sidney out of the way and tries to convince her she's going to be okay. Young Koschei gets into a fight with Old Koschei, both insisting they're the true Koschei the Deathless.
While the two are fighting it out, the Blue Fairy and the Fairy Godmother appear. Lindsey begs them to save Sidney. From her sleeve, she brings out a vial containing water from the spring on Neverland that heals and keeps the inhabitant of Neverland youthful. Most of the people in the Disney world experience the magic far away, through the distortion of time Sidney and Lindsey have experienced. However, drinking the water would be like drinking pure concentrated ancient magic, and giving it to Sidney would come with a cost. Sidney is unconscious, but Lindsey agrees for her to take it.
Young Koschei is on top of Old Koschei, and Old Koschei suddenly has a moment of realization. He had been so caught up in being free and taking on his 'imposter' that he forgot that his imposter is his younger self, and he's about to die—which he does. Koschei can only kill Koschei.
Sidney starts to glow, and is transformed by the magic becoming, what Lindsey recognizes as the enchantress from Beauty and the Beast, having rewatched the intro with the stained glass dozens of times. As she gets orientated, Young Koschei notices the group and sets his sight on them.
The Blue Fairy says it's time to perform the spell again, and Lindsey yells at her because last time it nearly killed Sidney. The Fairy Godmother adds that before Sidney was along, but the three of them together should have enough magic to complete the spell.
Young Koschei scoffs and continues to go after them with the Fairy Godmother shielding them from his attacks. The Blue Fairy pulls out a sword that was made by Hephaestus—though he didn't know for what purpose. Lindsey recognizes it, but before she can get a good look, the three have surrounded Young Koschei, with the Blue Fairy holding onto the sword. The three chant while deflecting Young Koschei's attacks, and eventually manage to subdue him.
When it's over, the Blue Fairy picks the sword up and mentions that she has to see it gets into a certain stone and leaves. The Fairy Godmother comments that she was always like in a hurry when she was younger. Then again she did have a lot to balance at that time, thank goodness that being the Fairy Godmother was being a whole less stressful.
Lindsey gives her a questioning look, but Sidney catches on:
Sidney/Enchantress: We're all the same person aren't we?
Fairy Godmother: That's right dear, just at different points in our timeline. You're the youngest, followed by the Blue Fairy and then followed by me of course.
Lindsey: Wait, is that why the Enchantress, you, and the Blue Fairy never really interacted all together? Like, you would cause the universe to explode or something?
Fairy Godmother: Dear, if us being together would have caused the universe to explode, it would have already done so. No, we prefer not to due to the déjà vu feeling it causes when we're all together.
Lindsey: But… I don't think I've ever actually seen the Enchantress once.
Sidney/Enchantress: I think I get it. Because you just told me you never saw me, therefore I never appeared in your presence.
Fairy Godmother: That's correct dear.
Lindsey: So if I say you once gave me a million dollars?
Sidney/Enchantress: It doesn't work like that, especially since you're obviously lying.
Blue Fairy (who just reappeared): Exactly. You would know that if you actually bothered to pay attention in your magic classes.
Lindsey: Yeah, but because I didn't, we're here now, which means I wasn't supposed to pay attention in the first place! I think I'm getting the hang of this.
Blue Fairy: Leave it to you to use time travel as an excuse not to do your homework.
Fairy Godmother: Now now, don't be too harsh on the girl.
Blue Fairy: You should get going, you still need to spread the prophecy across the universe. Don't forget to get the Fates in on it too.
Sidney/Enchantress: (Referring to an earlier scene with Hades returning frustrated from visiting them) They did mention something about pulling one over on Hades…
Lindsey: So you're responsible for the stupid prophecy? I thought it was nothing more than a bunch of mumbo jumbo of how Sidney and I were supposed to lead the heroes and villains in battle against each other, with only one side emerging the victor. Which started out like that, but I'm pretty sure with Koschei emerging from the sword it's more like a tie.
Fairy Godmother: Oh it is my dear, nothing more than a bunch of mumbo jumbo to ensure a certain set of events would play out so we could find ourselves here. It's funny what people will believe is true if you repeat it enough times.
Lindsey: So it really was nothing more than a stupid prophecy!
Blue Fairy: Yes Lindsey, it really was nothing more than a stupid prophecy.
Sidney/Enchantress: So… this was all about sealing Koschei into the sword, only for him to be freed in order to be killed by his younger self who was then sealed into the sword?
Fairy Godmother: There was more to it than that my dear. In the process, you spread your magic throughout time and space, planting seeds for stories that have yet to be.
Blue Fairy: Also, you became the Enchantress, and will someday become the two of us—all three of us have roles in stories as well.
Sidney/Enchantress: So what now?
Blue Fairy: I escort Lindsey back to the battle scene declaring that Koschei was defeated and the heroes have won the day. You sadly perished in the attempt to capture him. Meanwhile the Fairy Godmother has a prophecy to spread, and you have a Beast to curse. I'd suggest doing some research in Merlin's library before attempting the spell—he won't mind, just tell him I sent you.
Sidney/Enchantress: But no mention of who I really am.
Blue Fairy: No, no mention of who you really are.
Sidney/Enchantress then leaves.
Lindsey: Wait! But I never even got to say goodbye…
Fairy Godmother: Don't worry, you'll get to later.
Lindsey: I guess if you say so… hang on, the Cheshire Cat was supposed to show up.
Cheshire Cat appears: Did somebody say my name?
Lindsey: Yeah, I did. Look, you brought here from the future. Can you please go get me from the battle and bring me back here?
Blue Fairy: About twenty minutes earlier.
Cheshire Cat: I suppose so Not-Lost Girl.
[The Sidney/Enchantress/Blue Fairy/Fairy Godmother idea occurred when I realized that the Blue Fairy and the Enchantress looked rather similar, and the Blue Fairy and Fairy Godmother both had 'Fairy' in their names, and an affinity for wearing blue. It also went nicely with the idea of the trinity goddesses trope—the maiden (Enchantress), the mother (Blue Fairy), and the crone (Fairy Godmother). While Nimue isn't included in the Sword in the Stone, I figured it wouldn't be out of the realm of possibility for her to make an appearance and to know Merlin, hence him originally knowing her as Nimue.
Also, earlier in the story the Fates bicker about how many people actually know the outcome, stating anywhere from three to seven . The reason for the conflicting number is that it depends if you count the Enchantress/Blue Fairy/Fairy Godmother as one person or three, and whether or not they and the Cheshire Cat are present in the timeline when doing the math. Finally, as it was revealed, the entire prophecy was bunk, or as Lindsey called it, 'stupid'. Originally I was going to phrase it in a vague enough way so that could have applied to defeating Koschei, but then I realized, whoever said the prophecy had to be legit? It's been around since the beginning of time, the Fates are in on it leading credibility, so nobody would ever question it—except for Lindsey, who nobody really listened to.]
The Blue Fairy takes Lindsey back to the site of the battle, announcing that Koschei has been defeated once and for all, though Sidney gave her life in the process. She also declares the heroes the victors of the battle. The remaining villains join together for a final showdown, but Lindsey insists that everybody just stops. She explains that the heroes won, which in this case meant those who fought against Koschei won.
Instead, she proposes a truth, a magically binding contract between the two sides. The heroes would keep their lands, as would the villains—though the villagers would have a chance to move out and join the rest of the lands without prejudice if they so wished. Both sides are forbidden from seeking revenge or attacking one another. For example, if a hero would go after a villain, the other heroes and villains would be required to go after the hero. The same applies to any villain. If an outsider were to attack, both sides would be required to come together and defeat said outsider.
It takes a couple of days to work out all the legalities and get rid of any loopholes that could be exploited, but one is settled and all the heroes and villains sign their names to the treaty in a magically binding way that would have disastrous consequences should they go against it (losing their magic if they had it, being turned into a frog or newt, being forced to tell nothing but the truth and other creative ideas that Peter and Lindsey came up with). It's an uneasy truce, but is better than to continue to having battles, especially considering all those lost in the final battle. On the hero side—Roland, Archimedes, John Smith, Pocahontas, Prince Phillip lost a leg, Prince Charming lost an arm, Mulan now has to walk with a cane. On the villain side there was Jafar, Ursula, Hook, Shan Yu. Hades doesn't bother with bringing any of them back.
Peter, Teddy (who's been filled in on who he grows up to be), and Lindsey finally go back to the bridge, which has reappeared since, it always does appear when it needs to. Someday in its timeline it'll be destroyed, but an earlier version of it could still show up, which is explained to them by the Blue Fairy who helps with the treaty. At the bridge they are met by the Enchantress, who says goodbye to Lindsey one last time, and presents Peter and Teddy with the paperwork they'll need to prove they exist in the other world. When Lindsey asks what she'll tell their parents regarding Sidney's disappearance, the Enchantress tells her it's already been taking care of. The bridge should take them back to the morning after Lindsey left, and they'll find out that morning that Sidney was in a car crash. The car struck a tree and caught on fire, leaving little trace of Sidney. Lindsey is upset by her plan, but Sidney points out that she can no longer return to the life she had, and their parents deserve closure and wouldn't believe the truth. The sisters embrace for one last time before the group crosses the bridge.
Epilogue
The heroes and villains settle into a peaceful, though shaky co-existence. Hades never discovers who knew the outcome of the battle, because he's too busy with his new beau, Persephone, who decided to find after Sidney told him of the myth. Unlike the myth, no kidnapping is required.
Maleficent spends her time in her castle, trying to figure out what really happened with Koschei with little success.
