Technically, I don't believe that Brie's time as Nikki's assistant is up yet. I also think she's "faking" the heel turn and that when the time is up, she'll turn on Nikki and the two of them will start feuding over the title.
I'm also long since over the Punk chants. It was interesting initially and it was cool that fans were showing their support for him, even without knowing any of the details surrounding his departure. Now, however, it's become nothing more than the fans deciding they wanna be annoying. If you're not into what you're seeing, that's cool, but, at the same time, you also don't have to behave like a complete ass. I think it's also disrespectful to the other wrestlers. Even though AJ's married to Punk, she also has her own career and her own life so it's not all that flattering for fans to start chanting Punk's name during her matches just because of her relationship with him.
