Philipe and Sione:
I think it's a complicated thing, and Bob is mostly to blame with this thing. He shouldn't have had such a hissy fit when he first found out about the switch. Instead of crying with his team he should have encouraged them to work hard and learn new things through Jillian. He set them against her in a lot of ways... and made it even more difficult for her.
That said, Jillian made a HUGE mistake ignoring Philipe. He was hurting already, and she let it go. Also, it was her responsibility to follow him out of the room and talk with him. I think she would have done that for someone she gave a crap about.
So, it goes both ways I think. But the blame lies mostly in the hands of both the trainers and not so much with the contestants, I think.
Philipe was right though when he said that he shouldn't have lost focus. He was shifting the blame to Jillian but also recognizing he had some responsibility in the bad decisions he made on the 24 hour luxury.
I just wish he would realize that Bob is as much to blame, even MORE... for the distance between him and Jillian.
