There is a history with Don and his power logs that I don't think you know about. The last time it ended badly with his attitude getting the best of him and his wife stirring up a bunch of **** on several websites. I am hoping that he is right when he says that he has a "new attitude" and so far he has been pretty cool about it.
This is his second chance at this and unless he brings some proof that it works (NUMBERS/ TIME SLIP) I doubt that anyone will give him a 3rd chance.
