His birthday went better than he expected.

The others inside of the mansion didn't throw a full on party, they didn't even decorate, thankfully. Well, except for the man in the wall, someone put a birthday hat on his head that gave Sans a good chuckle when he saw it. There was no homemade birthday cakes, and when Sans saw the state of the kitchen, he could see why.

There was a lot of burnt cakes in the trash, and the stove was missing entirely with a broken window next to it.

He could only guess what happened to the stove and the window.

They didn't sing happy birthday, and that was also a good thing. They didn't treat birthdays like normal people did, they treated them in their own style. The cake was a bust, sure, but they did their own things to show Sans they knew him and cared about him, Sans's room showered with their gifts now. It was a good thing they didn't try to throw a big party, no one inside the house would have liked that. Maybe Sally, but that was it.

However, Sans wasn't really sure what to do about Flowey. After he gave the information, Flowey didn't leave, he asked to stick around and watch. Maybe it was the desire to be around people that finally understood where he was, or maybe it was the desire to watch more closely, but either way he was sticking around the house.

Was Flowey a CreepyPasta?

Now that Sans thought about it, he did share some similarities with the others. They all seemed to have tragic pasts that changed them as people, they were all killers as a result of what happened to them, and they all hated other people. Flowey could be a CreepyPasta, he could pull off a terrifying face and could kill a few people.

Flowey even stayed at the house past the day, curling into an old flower pot on the dresser in his room that Sans managed to find. There was no point in worrying about Flowey killing him while he slept, Sans was a light sleeper and he was faster and stronger. Even if Flowey did manage to kill Sans, he would have to deal with the serial killers in the household that would be angry. It was unusual to fall asleep easily in the same room of someone he used to hate, and it was even weirder to wake up and find that the yellow flower didn't even make an attempt to try and snoop or kill him.

There was no need to anymore. Flowey couldn't report the killers to the police, he still was a threat to monster kind, and the humans had already been warned about him, which was why the humans didn't go underground. And Sans had no reason to kill Flowey, his reign of resets was over, and he hated Frisk's resets just as much as Sans did.

That's how he ended up with the flower curled up around his arm, the pedals tickling the side of his skull as he looked through the fridge to try and figure out what to make for breakfast without a stove. To think that the flower could easily reach over with a vine and kill him right there should be terrifying, but it wasn't. Flowey never managed to kill him, and right now they were more allied than ever.

There was no need to kill one another, right now they both hated all of the other monsters.

This wasn't exactly the first time they had been on the same side, as they had both fought against Frisk during the resets. In fact, Sans could even remember one timeline where they had talked about the possibility of teaming up to stop them. Quickly that was discarded, as they realized that it would show that they had history and it would only make Frisk more curious. Follow the usual timeline and usual actions, and eventually the human would get bored. It was just a waiting game, really, they couldn't beat someone that determined. At the time, their hatred towards one another was still brewing, so they only allied against Frisk.

Now, it was different.

"Oh great, the flowers still here," Jeff grunted, walking into the kitchen.

Everyone had met Flowey yesterday, since he decided to tail Sans around the house. He had just explained that the flower was just an old acquaintance of his at first, which made everything think that he was like his old friends, before Sans quickly reassured that Flowey has killed before and had died before, just like Sally. That made most of them feel a bit better, but anyone from Sans's past was usually an sensitive topic among the killers.

Sally actually really liked Flowey, it caught everyone off guard. Obviously, the yellow flower was not a fan of children, but Sally giggled at everything he said anyway. Jeff, on the other hand, did not enjoy Flowey in the slightest.

"Oh great, it's the new smiley trashbag," Flowey mocked.

Probably because flowey thought Jeff resembled Sans in a sense and dubbed him the new 'smiley trashbag'.

"You need to teach me how to drive," Jeff muttered, leaning his elbow against the shoulder that Flowey wasn't perched on. "Seriously, it's getting annoying having to ask Toby to drive me places because I keep crashing cars."

"When we get a new car, I don't want to wreck the proxies car," Sans said.

"But they run over people with it! It's already had a lot of damage!" Jeff said.

"Now that's alotta damage!" Ben quoted Phil Swift from the other room, Sans and Jeff snickering at his comment.

"What does that mean?" Flowey asked.

"It means Ben's funny," Sans snorted, "Maybe I should actually buy some Flex Tape before I take you out driving, to fix the car with."

"Not even Flex Tape would be able to fix my driving," Jeff said, leaning down to look into the fridge with Sans. "You could take me driving to pick up groceries."

"No offense, but if we're pulled over by a cop when you're driving, it's going to be a bit troubling," Sans said.

"Is this what you guys do here all day?" Flowey whined, lightly head butting Sans. "Just sit around?"

"No, we do a lot of stuff, but we need food first," Sans said, "But we have no oven, and I'm pretty sure it was thrown out of the window. We also need to buy a new oven."

"We should go hang out again, do something," Jeff said, "Like how we saw Ma. We should do that again, it was fun."

"I think we'd have to bring Flowey along, and you two aren't exactly that close," Sans said, "You both are like me and self esteem. Never together."

"We could all go out and do something," Jeff said.

Sans had never turned his head so fast. "You mean like, all of you out in public? All of you together?"

"Laughing can make himself invisible, we have hoods," Jeff said.

"What about Slender?" Sans asked.

"He went out today, dealing with a problem or whatever." Jeff picked his teeth with his pinkie finger.

A problem?

Know what, Sans wouldn't ask, he didn't care. If Slender was the one who stole the documents, he probably had a good reason to why he would do it. And it only was about determination, no one but Sans knew how he was created.

It was fine.

"I think it'd be a bit much to have to... watch all of you," Sans said, "Before it was better because I was still technically a citizen and there were less of you, but now it's like an army."

"It isn't like can't go into public or blend in, how do you think we've managed to do it all of these years?" Jeff inquired.

"It doesn't feel like it, judging by how much you all act," Sans said, "Seriously, how has Laughing Jack never been spotted by all of the cameras in the world? He forgets to go invisible half the time."

"Yeah, I have no idea. He sort of just does his own thing."

It wasn't like Sans didn't want to go do something with everyone, he liked to hang out with all of them, it was just the downsides of dealing with that many serial killers. At this point, he was becoming a makeup artist from how much he has to make them look alive and normal, it was astounding. It would be hard to convince a police officer why he was with so many people, some of them hooded and probably armed.

On top of that, he would have to watch all of them. You would think that a serial killer would act more independent, but Sans was quickly proved wrong when a spider had entered the house a week ago.

He never heard serial killers scream so loudly before.

It was so sad to watch fully insane serial killers scream and run from a little insect that was less threatening than what they did for a hobby. Sally was justified in her reaction, as she was just a child, but the others had no excuses. Obviously Sans recorded the entire thing on one of Masky's handheld cameras, as it was hilarious to watch, but they still shouldn't be that scared of a tiny little spider.

"We can try, but we're going to have a team meeting before we go because I am not dealing with the police again," Sans said, pointing a finger at Jeff. "But you can choose where we go, I'm open to suggestions with food."

"Yes!" Jeff said, turning around to go tell everyone else.

"I should have left the underground earlier, this is way more entertaining!" Flowey said, "Am I allowed to come and watch?"

"Yeah, of course you're coming," Sans said, "Serial Killer road trip with their plus one, me."
