He may yet leave by the back door..he sure hasn't reacted to his warning(s) with any hint that he intended to change his behavior, and frankly, i don't think he has enough self control to do so.
There is a limit to how many times BB can look the other way especially if they have stated to him it was his "final" warning and at some point he becomes a liability and more trouble then he is worth.
I wonder if he gets paid if he gets ejected. Would be a damn shame should the vile creep be forced to stay nearly the entire time..then get thrown out and not paid

Toss him out a few days before the final and get all the media coverage.
