By his fifth year he's sure he's gay. Hogwarts doesn't have a lot of instutionalized homophobia, but it is very boy/girl centric (you have to bring a girl to the dance, ect.). So Adam never denies but never dates, either. He spends his energy working on his performing, drama, and keeping his friends happy. He's not sure he's ready for that yet.

(He thinks Taylor and Tommy are beautiful.)
