My 'gaydar' is spotty at best, but Elixir always 'felt' deeply in the closet to me. His backstory (being part of a hate group) would lend itself to keeping stuff buried, and the way he acted around his self-appointed 'rival' Hellion (who barely even noticed their 'rivalry') and his roommate Prodigy seemed a bit off.
Plus the way he made sure that he had a girlfriend (in Wallflower), and then pretty much ignored her to fool around with yet another woman, seemed like he was checking off boxes.
1) get a girlfriend,
2) I have no idea what to do next...,
3) bored now, maybe this 'girlfriend' thing will get more interesting if I cheat with a teacher? Maybe the sneaking around / forbidden nature of it will turn me on enough to let me pretend?
