Warren is the one who wears his s/o’s clothes because, IT SMELLS LIKE HOME, PISS OFF!! (His s/o is home) And he hates when his s/o wears his clothes because their his little ray of sunshine and they don’t want them to be wearing black leather and smelling like vodka cause he doesn’t want to corrupt them, so when their s/o goes away for a mission, he wears their favorite clothes and carries around their stuffed animal and endures all of Scot and Peter’s shit because he loves his baby so much
