The nightmare of Chara had ended, and from that came not only the return of Gaster who seemed rather hesitant in revealing how he was able to be back, but also the most radical change to the underground.

After Frisk had freed Asriel from his flower form long enough to obliterate the barrier she had assisted in the quickest integration of monsters into human society, she had after all, had many, many lifetimes to find out what worked and what didn't.

Grillby opened a line of bars and restaurants all across the world, there was no denying that the flame was efficient when he was dedicated and it took little more than some encouragement from the fallen human to get him started.

Toriel ended up making the first inter monster/human school in existence, it was a slow and, difficult time but it quickly became the most impeccable school of all.

Asgore, ran a flower shop, assisted by Asriel, or as he still preferred, Flowey, the two of them made a rather successful shop and had brought the most beautiful flowers to bloom.

Gaster, well, Gaster quickly became known as one of the most brilliant and, unstable scientists of all, but he did have a very capable assistant in Alphys.

Papyrus had become after a lot, A LOT of lessons, quite the well renowned chef, and his best meal of all was in fact not pasta, but instead a form of grilled fish.

Undyne became a personal fitness instructor, the type that even had well trained military personal snap at attention, be they sergeants or recruits and her results were undeniable as well.

…

And then there was Sans…

Well, sometimes, there is such a thing, as too much information….

"So kid? You ready yet?"

"Give me a second Sans, and would you stop calling me kid? I'm over twenty already…"

Sans enjoyed poking fun at her by keeping the nickname he gave her since he saw her for the first time, Frisk Dreemurr, a human that fell down and freed all monsters, adopted by the monster king and queen.

Despite how he remembered the little girl running around in the underground, 'dating' her brother, she was no kid anymore.

And that was proven over repeatedly whenever he saw her, but tonight was different.

They were going out dancing, a local club owned Grillby, Sans had to admit that, although Frisk's apartment was a very nice place, it only served to make the waiting feel even longer.

Sans was wearing a simple set of blue jeans with a black shirt and black hoody, he had the skull of a skeleton imprinted on the back with a bright blue coming from one of the eye sockets, this one he had designed himself, he expected Frisk to be wonderful yet the skeleton could have sworn he felt his jaw bone drop when he saw Frisk walking down the stairs.

She wore a simple black T-shirt, covered by a custom black hoody, a skeleton on its back with a dark purple light in one of the eye sockets, Sans chuckled when he saw it.

Despite the attire, it fit exceptionally well on her, but her eyes had locked him, dark pupils, lost in oceans of bright green.

…

"Sans?"

"huh?"

"You were staring…"

He noticed Undyne standing next to a bright red Frisk, she was pretty fashionably dressed, attire more suited for a romantic night than dancing at a club.

"I wasn't…"

"Hay bonehead, you were staring for the past ten seconds without moving at least once…"

He chuckled embarrassedly at that fact.

"So you gonna say something 'bout how she looks or what?"

"You look amazing Frisk."

…

"You don't get out much do you?"

"Hay you forget what I am fishstick, not a lot of humans are that interested in talking to a pile a bones…"

The two were about to get into an argument, and it made Frisk giggle, that stopped them.

Instead the both laughed.

"Well, you need to stop making these human girls jealous with how little you weigh."

"ha-ha, right after you give those guys at the gym a fair chance at beating you."

They laughed further before finally heading their ways.

"You really do look good Frisk…"

She smiled and took his boney hand in her own.

"Thanks."

It wasn't a long walk to the club and Grillby was happy to see them, more so, he seemed to actually be enjoying himself quite a lot, the lively music, the exhilarating crowd, it was such a radical change from Grillby's natural element in the underground but it seemed to be doing wonders for the flame.

Sans and Frisk both laughed when they saw the usually upright and strict, near butler type living flame rock it out on the dancefloor, when Grillby saw them he quickly headed over to them and gave them both a hearty hug, careful to not let the scorching heat from his unprotected form reach either of them.

"It's good to see you two, please, come, I'll grab something good for you two to en-"

Grillby noticed the matching Jackets and chuckled.

"You two really do make a good set you know that right?"

Frisk smiled at that before taking off her jacket, she was about to take it to a nearby shelf but Grillby snapped at attention, like some hidden butler genes in him had woken up inside him.

He took both her and Sans's jackets, taking them off to somewhere, else, not the same shelf where most people put their belongings.

After Grillby returned he told them to go dance before heading over to the bartender, taking over for a while.

They both enjoyed the moment for quite some time before Grillby headed over to the DJ and had him stop the music.

"I'm sorry everyone but tonight we have a very special pair of guests here tonight, two people I call very close friends and if it wasn't for them I'd still be underground, Sans, Frisk, thank you. So, I want to dedicate this next song to you two, especially you Frisk, Sans you were just sort of there."

Grillby laughed before having the DJ put the music back on.

Sans and Frisk, the most unlikely of pairs, human and skeleton, had a wonderful night, the dancing was a lot of fun for them both.

They were both surprised to see all of their friends waiting with Grillby, the flame merely said that he was surprised to see everyone show up.

"Uh huh…"

"Ha-ha Sans let it go, so they were a little jealous of our night and wanted to come see."

Asgore laughed at that.

"Well, you were both a sight to see."

"Yes, better than what we had planned." Joked Papyrus.

"Well, it's too late for photo's we, are going home."

Sans looked at her in surprise but she merely winked at him, the skeleton was rather curious at what she had in mind.

"Stay safe punk, hay Grill mind if I-?"

He was quick to accept her request, Undyne and Alphys both quickly headed to the dance floor.

While everyone headed their own way, Frisk and Sans headed to the exit, though they were both surprised to see Grillby standing ready with their jackets for them.

They both quickly left but Frisk led them down a different street that should be a shortcut.

"So, what are you planning, kid?"

"Ha-ha your, never going to give up the kid thing are you?"

"Nope, sorry."

"It's alright, but for that, I won't tell you till we're home."

"Uh, whose home exactly?"

"Mine."

She only smiled at him, the light from the moon lighting her face up.

He sighed but as they walked ahead they both immediately remembered this place, Sans summoned up a massive Gaster blaster without hesitation still before they passed the alleyway where the skeleton was to be grabbed.

Yet something else entirely happened.

They saw Gaster standing in the alleyway, hunched over the group that would have made the grandest mistake in the world, they were all dead.

"Gast?"

"Sans, did, you do this?"

"No, you?"

"No, this is very, odd, I did find this however, it is addressed to you, but I found it on the body of one of them."

Gaster handed over a paper but what was written on it only made Sans's head spin.

"Hello Comedian, first, let me say, ouch, that, hurt, but it was soooooooooo gooooooooood, thank you for letting me feel that, as you have guessed by now, I am alive, don't worry though, you did destroy me but this dark place, doesn't let me stay dead, and I'm not interested in taking Frisk again, even if I could I wouldn't, she already proved to be the perfect partner and I have no need for her further, have fun with this timeline, comedian. Signed, Chara…"

The paper slid free from Sans's boney fingers as he finished reading it out loud.

Gaster felt it before Frisk did and he immediately grabbed her, pulling her away.

Both Sans's eyes lit up, sending his arcane energy in all directions, raw power that would have done serious harm to Frisk.

Sans's emotional release was luckily reigned back in, but both his eyes were still glowing, giving him a very, unnerving look.

If Chara was really alive, if she really did somehow survive and if she EVER came near frisk, in one way or another, he would make sure that she wasn't going to survive.

Frisk giggled before telling sans that he really could a scary monster when he wanted to be, Sans chuckled before relaxing, dimming the bright fires of his arcane eyes.
