"Stay here." Who was that? Was that...Classic? Where did he go? Probably back to his house. But why? I-
(They suddenly remember the previous events of the day and get on their feet as soon as possible. After, they see their clothes.)
"Gah!" What happened to my clothes! Wait, these are my clothes...sort of. I remember putting them on this morning, but I kinda...don't? Why do I have 2 memories of getting dressed? And to make it more confusing, they're both at the same time! Who am I? What am I? Why don't I know?
I need to calm down. It's fine. I'm Sans. Sans the skeleton. I need to talk to Papyrus. He's most likely at Classic's house. How long have I been gone? How long have I been knocked out? Alphys is hasn't seen me yet, she's probably staying at Undyne's place. Well, that helps a little. I need to find Papyrus. And maybe some food, water, and/or mustard.
Wait. Why did I think of mustard? Isn't that Red's thing? But I'm Red...am I?
Oh sh*t! My SOUL! Is it okay?!
(They look at their SOUL.)
"AH!" What happened to my SOUL?! Did the core mess it up? Is Blue okay? Right, I'm Blue. Is Red oka-
"I'M RED!!!" Whoops. Said that out loud. Anyways, why can't I decide? Unless...
"THE CORE FUSED OUR SOULS!!!"
No, no, no, no, no, no, no! It isn't true, it isn't true, it isn't true!
"But it explains everything!"
"But it helps me with nothing!"
"It's the only answer!"
"No it isn't!"
"I know it's true!"
"No. I. DON'T!!!"
(The lone skeleton in the core started crying.)
I know it's true...but I have to keep going. Can I teleport?
crick*
"AAAHHH!"
(They fell to their knees and checked their SOUL. There was the slightest crack on the blue side.)
Guess I can't. Welp, I better start walking.
(They get up and begin walking towards the exit of the core.)
