Teacher Peter walks into a meeting wearing harem pants, a beaded tunic, a newsboy cap, and sandals with rainbow straps on them. A newbie raises an eyebrow and everyone rolls their eyes at the person’s confusion. They'll learn eventually. Also—Peter is the teacher who supervises the GSA group. He brings in cookies he made with Johnny and teaches the kids how to sew and do makeup and also listens and gives advice for dealing with shitty people.
Listen, teacher!Peter is there for his kids. He (canonically) helps out poorer kids, stays late with the ones who want to catch up on schoolwork, puts time and effort into making sure they’re ok. He knows what it’s like to feel isolated and overwhelmed as a kid.
