I completely understand why juliette is being like this with Joel. I think she didn't want to reveal anything about herself to him on telly, or make an effort to further what I'm sure she sees as a fake relationship.
I don't blame her.
He misjudged how much crazy 'me, me, me' one woman can stand.
I don't think she wants to be there and first chance she gets she will be off.
She doesn't need to be nice to him.
