[As someone from a very, very normal, non-magical world that-- was alarming. Not so much the sudden magical change of the world, that at least he can "get used" to. No, more the complete manipulation of his memories, who he is.
So this is probably the... third very visible breakdown he's had here, but he just has no ability to process any of this and even at the heart of it, this is all very terrifying and overwhelming for Yuuri. He's trying to hold it together. He's doing a really bad job of it.
He knows he should be looking for people - Victor most especially - but he's also just. incapable of moving, at the moment. Eventually he'll be able to wobble to his feet and at least try to be somewhat Normal.
For now, though... maybe he needs some help? Or at the very least someone should move him from the park bench he's currently sitting at, ankle-deep in water currently.]
