Fay initially just nodded at hearing his eventual answer, it was clear that it was a difficult thing to think about, even if it was only a hypothetical choice. Still, he couldn’t blame his twin for that hesitation. He had to smile very slightly, if only to himself, at the idea of Yuui travelling with a Princess for whatever reason, he had probably taken to that girl really easily. “You’ve been to a lot of worlds with her?”

He did his best to shake off the impending fear on going up high again; he should be used to it, right? It was hard to hide but it was worth the attempt if only to get rid of his brother’s guilty look. “...Some of them are bad?” It wasn’t really a surprise to him, the two of them had lived through being turned against by their own family after all. To go to another place and... He didn’t want to think that anyone would treat people that badly in a new place.
