I'm not sure Alex should have been fired (though he did suck as PM), but why was Chris saved? In hopes that he would create more drama they could promote? Alex being slack as a PM is the reason Angie wasn't prepared for the presentation, but all Chris did was buy things at Best Buy - and lose the credit card. Why was he saved?

Tana is the only person who has been PM twice and not lost. I think Craig and Kendra are each 1-0. It seemed like the people in the first season had all led twice by this point, and some had even led 3 times by the end. Maybe it's because the PMs weren't always fired in that season.
