Brians entire background story is a lie
Brian was a perfect pupil at school, a little cherub who studied hard and got all his grades.
He went to college and got a BA then onwards to wall st and then a break while he did his duty in the armed forces.
But this doesnt match with Brians current image.
He wants us to believe he was a "cold dead eyed killer" at school fighting of multiple attackers every day
He beefs up everything he has done to the point of it being ludicrous.
Brain realised what a pussy he was at 20 and then started to rebel, all the driving offences and minor brushes with the law made him think he was actually a somebody
all his attempts to not be a pussy ended up just showing him what a pussy he was (MMA 0-3)
He starts everything with a fanfare and gradually once he realises hes overshot with his ambitions he looks for someone to blame and hes the victim, which ironically re-enforces him being a pussy
