Grant...?

I like his character a lot. And I think he is a bit underused but I like his story lines. The "girlfriend", the therapy, him leaving, etc. But I have a question. Am I the only one who thinks he's gay? First, he's definitely shy and confused a lot of the time. Second, he gets angry and confused and leaves his online "girlfriend" and doesn't really know why. I think the writers are pulling it out a bit so as his character goes through more trauma with the family, he grows to become more alone and truly find himself and then soon accept himself. Even if that's not what's happening, it would be a good idea. And it's not like the writers wouldn't take the chance, they've already made Bird bi curious and added a homosexual female character in Season 2. I think that's what's coming in S3. Any other guesses as to why he's always stressed? Just his family or...?
