Frisk's anxiously paced around the whole castle by now, maybe more than once, they don't know, they've been looking for people more than the castle's endlessly-shifting features. They should be back. Chara-and-Frisk, that other kid, both of them. They need to find Chara, they need to talk to them before it's too late--

--they hear screaming.

They bolt from the hall they're in towards it, arriving at the bottom of the stairs (not the same stairs 'cause blood stained the cracks in that one even after they tried to clean it) and tearing up them on all fours like an animal. That was faster.

They're screaming too even before they're all the way up there, before they even see what's going on. "Chara! CHARA!"
