Dib being snippy with much of anyone was something Sollux hadn't seen much of before, and after nearly a month of watching him get increasingly snippy, Sollux figured it was about time to start actually getting worried about his boyfriend's mental state. They both knew that he was the one that got touchy and grumpy, out of the two of them. That Dib was being anything but slightly nervous and mostly sarcastic felt like it should be cause for concern.

He was used to the other popping in, having handed him a spare key months ago with which to do just that, and only looked up after the door had closed and Dib had spoken up.

"Going out of thtate for thome rethearch thing?" he asked, knowing that wasn't going to be it. Keeping casual seemed to be the name of the game, just to keep Dib from getting snappish.
