I don't think Eames is gay either, but I must point out that some gay people have children, either from a previous relationship, adoption, etc. So that's no "evidence".
Did you say adoption? - Oh... Man... I feel sorry for those kids already... no disrespect against gay people, but my only wish is that they just stay around their own circles and not to adopt a innocent child who doesn't even know what's going on in this world.
I am not going far now... let's stay in the topic.
Again... Eames is not gay. When he mentions his family. It's common sense. He's talking about his wife and kids.
