Now that I turned off that godawful music, I decided to do my duty as a psych student psychologist and see what's up with TSO's brother. Unfortunately, there's so little substantial data to work with... All I got was that he's a Weeaboo Juggalo who enjoys raving and drugs. His music is closer to noise, his anime choices range from okay to Naruto, and his "freethinking" is the same as everyone else's. Oh, and he says he's agnostic... I'm ashamed to associate myself with that now.
Say, do your parents give him a hard time with religious diddly-doo-da, or just you? Maybe you could make that work...
