Soooooo,

brown haired one is a separate character and, actually, red haired one's enemy;

red haired one never tried drugs - even thought he wanted to - if we don't count psycho meds, but maybe that would count since he sometimes overdoses or forgets to take his pills;

bald one didn't kill himself, and he actually was in love with red haired one.

I'm dropping this as hints here, being motivated to write some lore now. :D
