After beating cancer and completing a bike ride from Toronto to Pittsburgh, Brian reevaluates his life, deciding to take a more active role in his son's life and asking Justin to move back in.
In the fifth season, things between him an Justin seem stable until Brian buys Babylon and becomes envious of a new contender for his crown as Top Stud in gay Pittsburgh.
In the same episode, his son, Gus, is born to a lesbian couple - Lindsey and Melanie.
Because of the simultaneousness of these two pivotal events, Brian often associates Gus with Justin, referring to both as "sonny boy." During the first season, his relationship with Justin is unclear.
Upon Justin's release from the hospital, Jennifer Taylor bars Brian from seeing Justin but later asks him to 'take' her son, because Brian is the only one he trusts.
During the second season, Brian helps Justin recover, both physically and emotionally.
He is very vain and even narcissistic at times, but ultimately very loyal to his friends; especially Michael and Lindsey and ultimately Justin as well.
He pushes Michael away, so that he will go back to his boyfriend; he also helps Justin recover after a bashing at his senior prom, which Brian attended to please Justin.Brian is hurt when Justin leaves him to be with Ethan, but will not admit it.Despite his outwardly-detached nature, Brian's loneliness is evident in the beginning of the third season.Brian came from a broken home with an abusive alcoholic father and an overly-devout mother, and as a result, fears becoming "a shitty father" to his son.In one episode, George Shickle calls him "The love child of James Dean and Ayn Rand", as Brian often appears to practice Rand's philosophy of Objectivism in that he first helps himself so he is then better able to help others.
