From the frown on Yuri's face, it's clear he has no clue what a railway station is, but since he doesn't have a good term for where they are he's just going to roll with it. After all, the location seems pretty minor compared to Horrific Monster #1 (volcano head) and Horrific Monster #2 (tree eyes).

And really, Horrific Monster #3 (white hair). He watches this other version of Gojo split off and proceed to rip off #1's arm like it's absolutely nothing, grinning all the while. Seriously. Is this normal vampire behaviour?

Since there doesn't seem to be any danger up on the platform (it honestly seems like he's being ignored by the other humans, which is fine by him), Yuri rests his left arm against the automatic barrier and decides to keep on watching. He isn't flinching at the violence of it all, though he stares down at the other Gojo's smile with a thoughtful expression.

"Can that even happen to a vampire? You get so fucking old your mind rots away like some senile old human's?" His tone is derisive, but it's a serious question. If that's the case, or if it's some unknown quantity, he'd really like to be prepared for some future experiment involving it.
