Brian and Erin were married with Quinn and Daria in attendance as bridesmaids. After the wedding descended into chaos, he somehow slipped away and ended up in a bowling alley nursing a beer and swearing he wouldn't go back.

Presumably, he and Erin managed to make their relationship work for a while despite such rocky beginnings. They were still together a year later - though they were talking about divorce. Brian had insisted on a pre-nuptial agreement whereby they would split everything 50-50, even though Erin would ordinarily have been entitled to more than half. Despite this, Brian seems to decide he doesn't want to divorce Erin, and when he finds her at a spa in Europe they have a second honeymoon.

Brian worked in a government intelligence agency, though it's unclear which one. Actually, he was fired the day they got back from their honeymoon - which raises the question of whether Brian was lying about the whole thing.

He apparently has some chauvinistic attitudes, and a case of genital herpes which he passed on to Erin before they were married.

Quinn believes Erin should divorce Brian because "he's short".
