Not so sure. Although he seems straight, st first I also thought that Mike could be jealous, but then one statement puzzled me:
“It’s happened before, it’ll happen again.” Mike shrugged. “You always try to commit social suicide, but at the last second come crawling back to me. This time won’t be any different.”
What does he mean? Is Mike talking about Teddy coming out, when he stood by him, or did Teddy actually tryed to befriend other social outcasts, ending up hurting everyone? That had me thinking that maybe Mike is not a closed gay, but an overzealous friend
