Yeah, Dirk's tone and timing are way off right now. Not violent, per se, but definitely dangerous. He's pissed, on some level, and also pissed that he's letting on that he's pissed at all. It's stupid that he's so goddamn vehement about this, this one thing, and there's no way he's going to explain why he's upset, because he can't even explain it to himself.

And yeah, his grip isn't relenting. Dave's stuck here, at least for now, Dirk's arm around him a little more like a vice than a comfort now. It's clear he doesn't like Dave's answer, either. "You makin' a home here instead? Getting attached to people that are going to go through a revolving door?" He pauses. "You can't what?"

A dangerous question.

Then Dave makes up his shitty excuse, which Dirk knows is a goddamn lie, and for a minute he doesn't move. "I changed your diapers, you think I'm scared of a little piss? You were the pissingest goddamn baby the world ever saw."

But. He does let go, suddenly, and puts his glasses on, and stands. Impassive as shit. He remains there a moment, then heads off toward the front door. He pauses by it, briefly. "I'll be back later."

Dry. Blunt. Before, back home, he wouldn't have even said that. Would have just left and not said a goddamn word.

So it's something, and he hasn't quite left yet.
