Don't discount the possibility that Brett's parents are an interracial couple. Or that he was adopted.
In fact, now I'm picturing Brett's dad as a super-stereotypical Irish-Catholic cop and imagining what his relationship to his parents might be like, and the potential Brett backstories in those possibilities are making me super intrigued.
I don't know why people seem to limit themselves to headcanons based solely on last names or character appearances. It's so much fun to stretch the limits of things and go a more interesting way than what's right in front of you... lots of people have last names that don't mesh with what you would expect or backgrounds you would never have predicted.
