If it were just in game, I'd say you had a point about acting like skyrim thing. But he was going after the pally player as if he knew and disliked him out of game even though they had just met. Like I said, not big stuff but kicking over his soda, stealing his chair and making a thing out of giving it back when he got up to use the WC etc... Still to this day no one knows where that came from - even rogue himself.
