Alphys: Blushes “O-oh… Really…?”

Papyrus: “Well, I’m sleeping with my nappy brother! He’s not going to be much of a headache…”

Mettaton: “I’ll just put me at charge in this plug~”

Flowey: “I’ll be staying in my fucking pot…”

Asgore: “Dum Dee Dee~”

Mad mew mew: “Why?!”

Toriel: “Why what, lady?”
