Despite himself, and despite knowing the side here isn’t actually Real, Vincent feels deep concern as he sees Glass ‘em George take a sip from what’s clearly poison and collapse. He starts to move towards him to check his vitals, perhaps instinctively, before seeing Luca pick up that poisoned glass, and…
No no no no no NO NO NO-
There’s a vision happening- He… recognizes some of it, similarities to what he’s seen before and what Robert’s told him before, but with more parts of it he doesn’t know of Robert even knows about. The shotgun firing again leaves his ears ringing, which certainly doesn’t help his nerves or feeling of panic.
As soon they’re out of the vision again, Vincent soon finds himself on the ground, hyperventilating as he looks frantically around for Luca.

“Where- Where’s Luca. Did he really… just…”
Why why why WHY.
He knows Luca should be fine, should be alive in reality. But the last time something like this had happened…. Ellie had been…

“Please don’t mess with it. Please… stay safe,” he whispers quietly between labored breathing as he squeezes his eyes shut, as if in prayer more than anything as he tries hard to get ahold of himself.
It’s hard not to feel like this is his fault, just like Luca sticking his hand in that void had been. He just really, really hopes there won’t be worse consequences at the end of this projection too.
