I don't think it's all that odd to be friends with a gay person who wants you. As long as they're clear about it not happening and get it, it doesn't need to be an issue.
I don't know what the writers were thinking,having Jamie say that. JG would have been there for Willie either way and he was marrying Isabel.
I'm surprised at how quickly Brianna changed her tune. It hasn't been that long since she was angry with Claire. If she sends Claire back, she'll never see her again. That's kind of sad.
