* -_Cr1tikal_- asks: Yo g what was it like before [Y/N] showed up? (apologies if Sans didn't write it exactly)
G Sans: ...That's a real good question. That's when Papyrus got these really weird nightmares about her dying. Obviously, he's often dreaming about her execution day. Before she showed up, I had to deal the fuck with Frisk resetting. I had to stop hating the child since the Princess came along. I should be glad Frisk is around.
Flowey: YOU FORGOT ONE THING!
G Sans: Oh. I forgot. I jack off to Celine Dion.
Flowey: NOT THAT, YOU TWAT!
G Sans: ...Oh. I was kidding, though.

Flowey: Damn, G Sans.
G Sans: What is it?
Flowey: That's exactly how long I'd be playing my mixtape.
Gaster: liar. you wouldn't wear such shit.
