Irahl is absolutely neutral on the fact that Vincent has decided to stay and focus his attention here. In fact, he is so impartial that he mentally repeats this fact to himself a couple of times.

Likewise, it is out of pure ambivalence that he feels relaxed and content enough in this moment to bring his drink with him as he settles more comfortably back in his seat.

It often takes Irahl an extended period of time to become acclimated enough in a setting to move from casually slouching over his drink to casually slouching back with it, and in many instances, he never gets there. However, for one reason or another, spending time with this particular friend usually brings out that much more honest state of relaxation at some point during the course of hanging out. Vincent can hear that shift now as Irahl sits back like a normal person who doesn't look like they're ready to stand and leave at a moment's notice.

"Not just too used to cave shrimp?"
