It's a win/win situation for Michael. If he stays, he will get a massive boost, and hopefully scare off the three witches. If he leaves, he will have escaped the constant harrassment of Denise the bitch. Whatever happens, I'm sure he'll just accept it in his usual laconic and laid back style and be secretly relieved to not have to walk (as I'm sure he is close to doing).
I will, of course, be voting like mad because CBB is over for me if he goes, but I don't think he'll be too upset if he's evicted. I reckon Vinnie will need to go into hiding pretty sharpish though 'cos it'll be payback time
