Well, that is a lot of information he has no idea what the fuck to do with.
He's taking inventory as they walk, putting pieces— putting people— together in his head. Dream founded the place, Dream who loves his handler team more than some people love their mother, can't trust whatever he remembers there; there's a George around and as disinterested as ever, not a surprise. This other Wilbur founded his own country— he should ask someone later how and when and where and what's happened to it, what's going on with Techno, what's going on with Phil, why he'd have been in charge of the operation there. Quackity ran against him in the elections, was maybe his vice president— reassuring, really, that the elections went well; Quackity doesn't say it like it's the sort of thing that would be dangerous. He doesn't say it like there was anything at all strange about either of them running. What does that mean, for this place, he wonders? Was Quackity his vice president or someone else's, he isn't sure that Quackity would be his first pick for a right hand but it isn't as if other ideas exactly spring to mind, really the strange thing is that either of them ran at all— and then Tubbo's, but maybe this Tubbo is older, certainly him picking Quackity makes more sense— this Wilbur is, apparently, dead now, which is some number of things which Wilbur is not examining right now— Quackity fought against Dream, fair enough though he's curious how, and Technoblade, which he really can't imagine but presumably there was context, unfortunate how there's really not a delicate way to ask. Whatever the resistance might mean it must have been successful, or Quackity wouldn't be admitting to running it; he'll have to ask what the Egg might be or mean.
"Fascinating," he says, and means it more than he could say. "You've got your own country? That must be quite the undertaking."
