A few things are starting to weave together in Frisk's mind. just give up, i did and you'll never see 'em again and Gaster and Sans trying to be a weapon, once. Only starting, though. They'll have time to ruminate on things later; now, their mind's already preoccupied with the current subject and blank exhaustion.

"Made." It was more of a confirmation than a question. The hand not bothering with tracing the texture of Sans' head lifted to cover their eyes. "'splains why I freaked him out so much," they mumble, mostly to themselves.

Which leads them to another thought. "...how do you tell time stuff?" From what they sort of gathered from S4, it sounds like it could be dangerous. And they have to admit their own curiosity's a factor too.
