Last night on Barb, he was entirely disruptive: hitting people with jeeps (I couldn't catch him in a tk though), shooting the mg on a jeep for no reason and some marginal language. 6-Pak was kind enough to give him a time out which I assume is over now.
Maybe he was drunk or just a kid. Anyway, if you see him/her/it, pay attention to see if last night was an aberration or an omen of things to come.
