Oh God, not Ellie being in the way as he's leaving, this REALLY is just his luck- Though before he can say anything to her as an apology or try to slip by, into the projection they both go. Wow, the wardens are REALLY bad at keeping people out if they actually didn't want them here. But here comes the projection now!
And then… huh. The neon lights at first make Vincent squint, trying to get used to the total change in lighting going on. Ah, right, even Vincent himself was wearing almost all white now from the straightjacket instead of his usual primary black, of course it would all glow. Hell, even the white sections of his HAIR are glowing in the blacklight! And when he's able to actually parse what he's seeing before him…
Well, the FIRST thing he actually reacts to is the gun being waved right at the lot of them, non-gun material or not, and Vincent immediately stands very still, posture stiff and upright. He doesn't seem panicked about it, necessarily, and his face stays perfectly neutral, but he's clearly on high alert all the same. Vincent stares at it until its lowered, before he takes a slow breath and flicks his eyes between the two of them as they respond to the wardens.
…Ah. He sees, he thinks. After a moment, Vincent gives something of a bowing nod to them both. Though seeing Kaoru walk RIGHT up to a gun like that does also make Vincent keep his guard up even as he does.

"Apologies for intruding; The situation is a bit strange, as I think the only reason we can see and talk to you both is because of a machine Robert is synced with at the moment. I at the very least am not here for any purpose but to make sure he and… you both? are alright." Sorry he didn't get Out in time, but now that he's here, he's here. "If you aren't Robert, or don't answer to that name: What should we call the both of you?"
Vincent takes a peek at both of them as he asks, but since Kaoru is going up to the cowboy, Vincent looks over the angel in particular a little more too, if there's more to see there-
