Even without the memories being Vincent’s, and knowing they aren’t, it does feel freeing to have that sense of weight off his shoulders. Distantly, he feels almost jealous at how easy it feels to be rid of everything heavy like that right now, but… it’s easier just to allow himself to soak in the moment, as the feeling of elation comes. He can’t remember ever really feeling like this himself, not for prolonged amounts of time at the very least. He doesn’t need to try to think about it. Not right now.
The feeling of relaxing for hours like that, looking at the sky… it’s nice. It’s peaceful. He doesn’t have to think, for once.
…And then, it ends with a body in the fire.
……….
Upon coming back to reality, Vincent looks contemplative, serious as per usual of course, but more quiet and thoughtful than dark and moody. Things were indistinct enough at the end that he’s not panicking, certainly, nor does he even look Upset, either, even with the foreign feelings of peace and elation now gone as the projection is too.

“Huh. That was… strange, but not overly stressful. …Are you doing alright too, Tatsuko?” He doesn’t want to stop the process of her Being Freed, but he’s not quick to leave the room either. “And if you… do want to know what it was we saw, I don’t mind relaying things to you. It’s up to you.”
He’d apologize for being here at all and seeing personal things like this to most other people, but given Tatsuko had said in advance it was ok for him to be here, he finds that unnecessary.
