Frisk slowly turned around to meet eye sockets with a red glow in them. This Sans was scary, to say the least. Various small cracks were on his skull and his teeth were sharp, one of them being golden. His jacket was black with a few red bits. His shirt was a dark red and his basketball shorts had a red streak instead of a white one. Frisk and Flowey just stared at him, which seemed to get him annoyed.

"okay, I'll repeat myself." Sans said as he took a step closer to them, the red light in his eye sockets shining dangerously. "did you kill her?"

Frisk shook their head quickly, saying that they would never do that.

Sans stared at them before turning around and knocking on the door with a simple, "knock, knock."

A brief pause before: "Who is there?"

They could almost feel the relief in the air as he answered, "orange."

"Orange who?"

"orange you glad you're not dead?"

Laughter was heard; it sounded slightly insane, but they new it was Toriel.

"heh, glad to hear your voice, lady."

"Yours as well." Toriel replied.

"so, you just let the kid through?"

"What else could I do? They refused to fight..."

Sans looked at the child. "heh, let's see where that gets them in this world... heh, well gotta go."

"Goodbye..."

Sans walked away from the door and crossed his arms, staring at the two in front of him. "so, you aren't gonna kill anything, huh?"

Frisk shook her head.

"you're lucky that i know what's going on here, or else i wouldn't hesitate to bring you to boss."

They asked what he meant by that.

Sans just shrugged. "just that you're staying with me until classic finds a way to get you back to your world."

They just tilted their head as Flowey asked, "What the heck are you talking about?"

"heh, guess i'll just let him explain it." Sans said as he took out a strange, phone looking device. He typed in something then held it up to his ear.

"yeah, i got the kid. a flower too... i guess so... eh, yeah, that's why i called, idiot... oh, shut up!"

He then angrily gave Frisk the phone, crossing his arms. Frisk looked at Sans before holding the phone up to their ear, saying a small hello.

"heya, kid. this is the frisk from my timeline, right?"

Frisk could barley hold in their joy as they shouted the name of the voice they heard. This was Sans. The Sans that they knew.

"heh, ya miss me, kiddo?"

Frisk said yes, not hiding the excitement in them.

"heh... okay, so here's the deal... you're trapped in a completely different timeline, and i'm not sure how to get you back yet... and, uh, this timeline you're in... isn't exactly friendly... i want you to stay with red over there. keep yourself hidden, and keep yourself safe, okay?"

They answered with a small okay.

"oh, and one more thing... is that the flowey from our timeline?"

Frisk told him yes.

"great... okay, so just make sure he doesn't meet his other self."

Though they were confused, they answered okay.

"okay... i'll see you later, kid."

They told him goodbye and handed the phone back to the other Sans.

"okay, so what's the plan?... wait, what!? i can't let them stay with me! boss will kill both of us!... ugh, fine." He then promptly hung up and stuffed the phone back in his pocket. "alright, kid. seems like you're coming with me."

Frisk and Flowey followed him to a bridge with a lot of spikes on it. It doesn't seem passable, but Sans grabs their arm and teleports to the other side. After that, he doubled over, hands on his knees, panting.

Frisk, worried, asked what's wrong.

"eh, i'm fine, kid. just not use to teleporting with someone else..."

"SANS, YOU IMBECILE! WHERE ARE YOU!?"

Sans flinched. "oh no... kid, go hide behind that lamp over there. go before he comes!"

Frisk obediently his behind the lamp, Flowey set down in the snow behind them. They peeked out and saw Papyrus stomp into view. Frisk had to do a double take at the once innocent, kind skeleton. This version had a red scarf, yes, but it was torn and ripped in many places. His whole 'battle body' actually looked like a battle body, it being black and a red that looked like blood. His teeth were sharp and his eyes were narrow, and Frisk could see a large crack on his head. He stood tall with authority, and Frisk could see Sans shaking like a hurt puppy.

"h-hi, boss!" Sans said, obviously trying to act casual for them. It wasn't working.

Papyrus glared down at his brother, distaste clear in his eyes. He held up his hand and-

Smack!

Frisk was surprised, to say the least. Did Papyrus just... slap Sans? They peeked out again to see a clear mark on Sans' cheek. Their eyes were wide as they stared at the scene with shock. They even blinked a few times to make sure they weren't seeing things. The whole idea of Papyrus hurting someone, especially Sans, just made their stomach turn. They looked back at the scene playing out before them, Papyrus was forcing Sans to look him in the eyes. His voice was quieter than they were use to hearing.

"You know better than to not answer when I call."

Then he let go of Sans, walking away. He stopped before he exited the area, saying, "You are expected to check on your puzzles then return home."

When he was gone, Frisk grabbed Flowey and quickly ran to Sans, asking if he was okay.

"heh... i'm fine, kid. he's done worse..."

Their eyes widen; how could Papyrus be so cruel?

Sans looked at the kid's shocked expression for second. Then it hit him. "oh right... your, uh, p-papyrus..." As soon as he spoke the name he glanced around with a small amount of fear. "he... is nice, isn't he?"

Frisk nodded, saying how he was the nicest, most innocent person they had met in their whole life.

"heh... well, welcome to my world. all of those 'nice monsters' are gone. in this world, it's kill or be killed. no mercy."

Frisk frowned, but their face grew into something else. Flowey knew that look well.

"Frisk, we aren't going to do anything. We are going home as soon as possible."

But, seeing Sans in this state and knowing the whole world was like this...

It filled them with determination.
