Gamzee was at his computer, responding to some messages. He was either so absorbed on his computer that he didn't know you were there, or he chose not to say anything.

After a brief period, he turned to face you, a dopey smile on his face. Gamzee doesn't look surprised... he waved at you.

"Do you need anything, or did you just motherfuckin’ come by to say hello?" — Gamzee asked, laughing. He seemed to be friendly.
