Part 2

You were a bit upset that your friend Josephine couldn't come again today. You had picked up a sandwich at a nearby shop and are now waiting in the park for Sans. You've been waiting for at least half an hour now. You finished your sandwich and started walking around, looking for Sans.

After a short walk around the park, you turn to go back to where you started. You spot Sans sitting on a bench with his hoodie covering his face again. You walk over to him.

"Hey Sans" You say as you sit down next to him.

"Hey y/n" Sans says as he pulls the hoodie away from his face, but still keeps it over his head.

"So was there something you wanted to talk about?" you ask Sans. You were still a bit concerned about why he acted . . . absent. The look in his eyes, the way he hides himself, it concerned you, even if you barely knew Sans.

"Oh, heh. Yeah, about that-" Sans starts to say, but suddenly stops and pulls his hoodie over his face. You can hear him mumbling something like "not now" over and over.

"Sans?" You whisper to him.

"y/n, please go" Sans says quietly. He is shaking.

"What?! No, I want to know what's wrong so I can help you" you tell him. You put a hand on Sans's hoodie to try and lift it away from his face. As soon as you do, a blue aurora surrounds you two. Before you have time to react every turns blue, then black.

~~~*~~~

You land with a thud onto a tiled floor, your head dizzy and your body sickly. Everything seems so bright here. You sit down as you hear cracking and a yelp off to the side of you.

"Alphys! Help! Quickly!" you hear a growling voice call. You look over to where it came from. It's Sans! At least you think it's Sans, it doesn't look like Sans, but it has Sans's jacket. It looks like some sort of skeletal dragon humanoid.

You watch as a yellow monster in a lab coat comes running over to the Sans like creature with something cupped in her hands. You don't know what it is and you didn't get to see what she did with it. The Sans creature was facing away from you.

The yellow monster steps back and you watch as the creature slowly shifts back into the Sans you know. You gasp as you remember the rumors. Sans is the monster from the rumors. The monster who could change his form. You start shaking. Sans turns around, shocked at seeing you here.

"y/n! y/n! Hey, I'm fine! y/n!" Sans almost yells at you. He starts to walk over to you, but stops when he sees you get up and start backing away. You can feel your eyes start to water up, but why? Shock, fear, both?

"Sorry I scared you there kiddo" Sans sighs.

You continue to back up, your hand over your mouth. You back up until you trip and fall over some large cables and wires.

"Listen, I never meant for that to happen, and I-" Sans starts to say, but you cut him off.

"I-I just n-need a moment" you say, your breathing heavy. You were never really that scared about the rumor, but now you are scared, scared about what might happen next.
