That… huh. Who the hell was this man in the vision? Clearly not Kaoru(?)'s dad, going by the last line there. By the time he's back in reality, Vincent's eyebrows are furrowed with thought, trying to figure things out.
 
He does try and tug the fabric and open the trunk, but no dice (unlike the fuzzy dice in the Kaoru-car, that is). Just as he's going to head back around to look at what else the car might have, perhaps the driver himself, he spots the Kaoru-figure moving and tries to watch, before-
Oh, Fuck.
This last bit, not quite vision as it's feeling like it's happening, it Looks like it's happening, is Way more intense than any of the others seen before, and Vincent's vision is a blur of blood and events and choking and Red, and then it's over, it's ALL over.
But is it? Because despite the projection having fully ended, the sensations still feel like they're burned into Vincent's mind, like he's seeing things that aren't quite there as his breathing is ragged again, outright struggling to register that reality is back to the courtroom proper again for multiple moments as he distinctly doesn't look all there.
His entire body is tense, and by the time he realizes that he's just in his own head and not still in the projection, he has to squeeze his eyes and hands both shut and audibly count under his breath, fingernails digging into his palms a bit. His voice is just a mumble, but it's still not hard to tell what he's saying this time.
Eventually, he does open his eyes, darting around the room for a bit before trying to focus on specific things actually present here.

"It's… over, right…?" Right? His body REALLY still wasn't convinced it was, but it had to be by now. Kaoru was here? Kaoru was here. So was everyone else, too. And Vincent himself was… ah, he was kneeling on the ground, when had he started doing that? Definitely over now, he's more sure of that now. "…Okay. Yeah, it's over."
One more slow breath, and then Vincent stands up, still looking Slightly out of it but otherwise functional again.

"…….I think there was a lot of context missing, but… I'll have to think about it. Lot of… pieces." Karma… karma…. hm…… Who was the person there, and what had they done…? He's gonna have to slowly mull over that later, though, because right now he feels a headache coming on as he glances at Kaoru.
 
Despite everything, though, he doesn't look any kind of upset at or about Kaoru, just watching him and certainly not letting himself be pushed out of the room right away just yet until he sees that Kaoru's being released. Much to consider, but for now, he just offers a nod. He'd been here like he said he would be, at the very least.

"…Lemme know when you wanna talk, just give me a little." To get his bearings and just… process all that.
