I called it first scene they had with Adam and Eric

I certainly didn't see it coming at least in the first few episodes. Adam in the first 5 or 6 episodes always had a rebellious attitude, but I didn't catch any bisexual undertones. I felt like his coming out was kind of forced and only there to appease the story line. I was also confused as to why Eric even let him do oral considering their negative history. Sure Adam was physically attractive, but he also humiliated him on multiple occasions, even publicly AKA tromboner, but yet maybe he is just that desperate? It didn't make sense for Eric's character, who had just taken a major step an episode or two before, where he accepts himself, stands up to his dad, Adam, and essential the entire school, yet the biggest bully in his life, he just lets him continue to bully him in an emotional way.

Saw it as well. Adam was almost obsessed with hounding Eric every time he saw him. I remember thinking, "I'll bet Adam ends up in love with him." And he did...great show!
