Prologue

Lily Anne Potter locked to door to her daughter, Mary's nursery and cursed the day she let James convince her to leave her hunting gear behind. She also knew that no ring of salt, holy oil or protective symbols would keep Voldemort out, her daughter safe and her alive. She knew her husband was dead, it didn't take a genius to figure that out. "You're screwed darling. You're screwed" a voice in the back of her brain said that sounded suspiciously like her old friend Crowley. "Shut up. I know I'm screwed." She thought annoyed as she picked up her daughter. Mary Elisabeth Potter was barely a year old and had no idea what was going on. Her emerald eyes were wide with fear. Lily knew she was going to die and she was going to accept it like a hunter. She only wished she could go down fighting than being killed without a chance to defend herself. Then a thought struck her, it was a crazy idea but it was probably better than having Mary live with Petunia.

"I'm nuts to so much as even think of this but I know he'll do anything for me and he'll keep her safe." Lily muttered as she waved her wand in a complicated pattern to break anti-apparition wards.

When she finished, she picked up her daughter and whispered softly:

"Mary, everything's going to be alright. I'm taking you an old friend, he'll look after you. Mary, mommy loves you. She loves you very very much."

That was when the door exploded and Voldemort stood in the entrance to the nursery. Lily spun around to face him, her eyes burning.

"Stand aside. Let me at the girl and I will let you live." he hissed

Lily looked him in the eye and said:

"Never."

"Stand aside you silly girl." He hissed

"Never, I'll never let you near her." Lily snapped getting ready to apparate out

Voldemort pulled out his wand and yelled:

"Avada Kedavra!"

Lily apparated but the spell followed her as she disappeared and it hit her just as she was landing in front of her friend. The last thing she remembered was the shocked look on his face before everything went black.

X-X-X-X-X-X-X-X-X-X-X-X-X-X-X-X-X-X-X-X-X

Crowley was feeling particularly smug as he watched the Winchester brothers flop on Bobby's couch, their angels watching them. His mate, Bobby was sitting in the arm chair.

"Sit up strait you idjits." Bobby muttered seeing what Sam and Dean were doing

"Can't. To tired." Dean muttered

Bobby opened his mouth to retort when a sharp CRACK echoed around the room. Everyone looked up and saw a young woman with long copper coloured hair and emerald coloured eyes, she was holding a baby in her arms. She has panting slightly and looked slightly relieved. That was before she let out a little gasp and fell after a flash of green light hit her in the back.

"Lily!" Crowley shouted as he darted forwards to catch her before she hit the floor.

"Lily! Lily, what happened?" He shouted

"Crowley. Who is this?" Bobby asked

Crowley didn't answer, he just took her pulse. Nothing.

"Good luck with that. I'm dead Crow." A female voice spoke

Crowley looked up sharply.

"Hey Lils. What happened?" He asked

"Old Mouldyshorts payed us a visit. I am wondering what the hell I was drinking when I let James convince me to leave my gear back in our old house before we went into hiding. Had he not, I doubt I'd be dead and talking to you as a ghost." Lily said

Sam and Dean lept to their feet going for their shotguns.

"Relax Winchester, I'm passing on, so kindly don't get your knickers in a twist you three. I just need to talk to Crowley for a minute, I've got a few things to tell him." Lily said

"How do you know us?" Sam asked "And what do you mean by you three?"

"I've heard your stories. The ones where you prevented the apocalypse, you guys are practically legend." Lily said "I'm also talking to the reaper who's hanging around waiting for me to finish up."

"You said you needed to tell me something." Crowley said

"Well, it's more of a request than anything else. I want you to look after my daughter. Think of it as a request from an old friend Crowley. " Lily said seeing the look that crossed the king of Hell's face

Crowley sighed, he didn't want to do it but, she was still his friend and he had loved her.

"Fine, I'll do it." Crowley said with a sigh

"Good, now, I have a couple of questions. Did you hear about someone named Tom Riddle?" Lily wondered

"Yeah, sold his soul to me so he could get the courage to kill his dad. He had a 30 year contract. Why?" Crowley asked frowning

"That leads to my second question, Can you get out of a deal by splitting your soul into 7 pieces?" Lily asked

Crowley snorted rolling his eyes.

"Do not make me laugh Lilian. Nope, you can't do that, I'd send out the hounds to collect the pieces and ship them off to hell. Why?"

"It wouldn't be because of the second soul that has lodged itself inside your daughter?" Castiel asked

Lily opened her mouth and then closed it.

"How did you... never mind, you're an angel. Yeah, sort of, thing is, I found out that he had invented these things called horcruxes that essentially house bits of a persons soul. Did a bit more digging and I found out he made six of them. And for the final time Crowley it's Lily!" she snapped before pausing and muttering: "Well, technically he made seven if you include Mary."

Crowley let out a angry hiss, he really hated it when wizards pulled that little stunt, it never worked anyway. He muttered something that was not very polite and summoned his hellhounds. Speaking in hellspeak, he ordered them to head out to England and retrieve the soul pieces. Crowley sighed and rubbed his temples a little peeved.

"I'll take care of the soul piece in Mary's head myself, it won't hurt her, at least I don't think it will. Anything else Lily?" He said

"A couple of other things. One, you were right about James, he was a dick, didn't want anything to do with Mary when I was pregnant with her and after she was born, I am wondering what the fuck I was drinking when I agreed to marry him." Lily said

Crowley snorted before taking a sip of his whisky.

"I told you so." he said

"Shut up Crow." Lily snapped

"Make me darling." He snipped

Lily gave him the one fingered salute and Crowley placed his hand on his chest and pretended to look offended.

"Anyway, this last request is probably the most important, keep Mary as far away from England as humanely possible." Lily said

"Why, what's wrong with England?" Crowley asked

"Well, knowing Dumbledore, he'll try to use my daughter as some kind of sacrificial goat for his twisted idea of the greater good. Well, that or some kind of disposable pawn in his plans. Something along those lines. I don't know." Lily says crossing her arms

"Dumbledore, why have I heard that name before, what's his first name?" Crowley asked frowning

"Albus. Why?" Lily asked

"Wrong Dumbledore. I must be thinking about another one, father most likely." Crowley muttered as he picked up Mary "She's got your eyes."

"I know, she'll be quite the heart breaker when she's older. Be sure to burn my body, I'd hate it if it were used to make an inferius." Lily said

"What's an inferius?" Dean asked

"A dead body animated by dark magic. If you want to kill one, get your hands on a flame-thrower." Lily explained before groaning "Alright Ms. Impatient, I'm coming. Sorry boys, but Tessa over there is getting impatient, I'll be keeping an eye on you Crowley, you'd better take care of her." Lily said fixing him with a sharp stare.

"I will." He said

"Good." And with that she was gone

Crowley sighed as he stared at the place where his friend's ghost had been. Bobby's voice interrupts the silence:

"Crowley, explanation now."

"Well, that was Lily Potter nee Evans, she's an old friend of mine and I haven't seen her in a couple years due to the fact she got married and had to stop running around across the States with me. I taught her all she needed to know about the supernatural. She was quite the hunter. She was also my best friend and for a good long time, I was in love with her but she was seeing someone else." He paused for a moment before he started talking again "You remember that time you had dig that rock salt from my back, that was her. Before you ask, I pissed her off, her shotgun was the first thing she grabbed and it just so happened to be filled with rock salt. People weren't kidding when they said the ire of a readhead is a dangerous thing." Crowley said

Dean cracked up. Sam and Bobby looked at him in disbelief.

"She was the one who shot you! You said it was another hunter you lying idjit!" Bobby snapped

"Why would your own best friend shoot you?" Sam asked

"She was mad at me." Crowley said rolling his eyes

"Why was she mad at you?" Sam asked

"I forget, it was four years ago." Crowley grumbled "Anyway, she's dead now and I've got to look after her daughter, Mary."

"I got that, why didn't you tell me about her?" Bobby asked

"If you had a friend that you were madly in love with and it hurt when you so much as thought about her because she was in love with someone else, you can understand that it would be rather hard to talk about her do you Robert?" Crowley said

"I know the feeling, been there done that don't want to do it again." Dean said

"This friend wouldn't happen to be Cas would it Dean-o?" Gabriel teased

"Shut up Short Stack." Dean snapped

"As amusing as your argument is, I need to take care of Mary's extra soul piece problem. And Lily needs a hunters funeral. I hope I can trust your skills to give her a proper one and ensure that she can't be resurrected for nefarious purposes." Crowley said rolling his eyes

"We'll help, I have heard of cases like this involving conjoined twins, sometimes their souls merge and they have to be separated. It is not difficult, I have done it before." Castiel said standing up "Gabriel, will you give me hand?"

"Course Bro."

The ritual didn't take long and soon, Castiel, Gabriel and Crowley had joined Bobby, Sam and Dean outside for Lily's funeral. Mary was sleeping off the ritual in Crowley and Bobby's room. Crowley watched his friend burn and silently promised to honour his friend's final request.

And that's that. I hope you all enjoyed. Flames will bu used to torch wendigoes and toast marshmallows. Read, like and review. Later Dana.
