I do remember him listening (and playing air guitar) to his music in there, but not much else. There were a few times people were in there, but it was usually a group thing that was planned.
I also remember him cooking for hours at times to make a meal and would sit there and eat and talk to someone he was on the outs with in the game, etc. He could separate that better than ANYONE I remember in this game (with the exception of Jen of course).
He was always in the yard mainly so he could smoke while talking too! But, I do remember him saying he did lock the door for that reason.
