I think it is all totally scripted. Bob and Jillian were a team but that made the rivalry less dramatic. Bring in a new person and this time THIS MEANS WAR..
I hadnt noticed Bob's hair last week. Seriously. WTF. That looks like what happens when a 2 year old finds the trimmers.
Lost successfully, maintained successfully. Followed by a whole lot of setbacks and obstacles. Starting over with the knowledge gained before.
