He lingers just past the doorway for a moment, slightly uncertain; he spares a brief glance for the additions to Sollux's collar, which as far as he's concerned look like they can only make it less comfortable to wear – never mind how he got them on in the first place – but he figured the first time he saw them that that's probably the not the point. Kind of dumb in his opinion, but whatever. "You busy with shit?" he asks, sort of hopeful that he isn't.
