Okay I just watched it again.
I honestly don't even know why the words "I love you" would change big brother forever regardless of who says them. Even if Clawson says it... how is that such a game changer? They've already toe-fucked for crying out loud

. Unless, of course, the Candice relationship has been bullshit all along and Cat and Lawson have been acting the entire time. It's all a bit odd.
Mind you I am really cynical when it comes to the promos, I don't believe most of what is said unless it's really specific.
