From what I've heard, even if they're not here, when you eventually come back, it'll be like you never even left! Which is basically why Elsa and I are taking it so well; I mean, if that wasn't the case, Arendelle would have a little bit of a crisis! But thanks to some kind of weird timeline mumbo-jumbo, it's kind of like, y'know, a month here is like a millisecond wherever you're from? Something along those lines!
