I agree that Anna seems to be really soft. I don't think you necessarily have to yell at the contestants in order to get them to work out (I would hate it if I had a trainer who yelled at me) but she also doesn't seem to be pushing them very hard.
I got lost in the whole black team drama, too. Since we didn't see the incident, and I still don't completely know who is who, I wasn't sure exactly what they were mad about.
Maybe the contestants weren't allowed to work out during the time they weren't with their trainers, since they were talking about having to learn how to fit working out into just a few hours of the day? But what did they do for the rest of the day? I know a couple of seasons ago they were teaching the contestants the same thing, but they actually worked all day.
Also, I'm not sure I agree with the decision to send Johnny home. Yeah, he kind of slacked off this week, but I think he learned his lesson, and was due for a good week the next week. I know Bonnie works hard, but with her injury she isn't much help in the challenges and also isn't losing a lot on the scale.
