To think he once thought lasers on conveyors were bad. They're nothing compared to this moment in this place. This is Papyrus' least favorite nightmare.

Papyrus flinched a little at that, hurt for a split second... But no. Sans is the one hurting, here. There's no way he would talk like that if he wasn't so out of sorts that he couldn't cover it up. One of them needs to be the bigger skeleton, here.

"No, it really isn't," Papyrus agrees, slowly and solemnly. He straightens a little harder, and does his best to look heroic and reassuring. "I can see how much pain you're in from forgetting me! I knew I was a big part of keeping you together, but I never suspected it was this much. Don't worry, Sans! I'll help you find your missing memories. Then I can wake up, and this will just be a bad dream."
