Increasingly, Bones has been separated into two kinds of episodes, Booth and Brennan episodes and regular episodes, with stark differences in quality. Booth and Brennan episodes used to be the highlight of the show in the first couple seasons as the cases actually reflected on their characters and they grew through the course of the case. These days, however, Booth and Brennan episodes focus on whatever inertia is holding them back--Hannah in the case of the six season. The case running simultaneously with the relationship problem is given less time and there's a detached feeling to the crime solving.
"The Body in the Bag" has a few running themes, cultural identity and counterfeit goods, but the conclusion is quickly shoehorned into the episode after a miraculous facial reconstruction. As it turns out, the "Prada police" slept with her and later killed her. He's arrest and it's over--no follow up or anything.
It's necessary to talk about the relationships since so much of the episode was spent on it, but at this point, you can't expect much. Brennan and Hannah are back to being good friends--exactly where they were at the beginning of the episode. It seems like the writers don't have a good plan and are just circling until they can think of something good. We all know the endgame is Booth and Brennan together, but Hannah and Brennan are really good friends instead of the mortal enemies you'd expect, which is very problematic.
The episode has several strong points with Angela and Hodgins, and Clark finally showing some interest. These elements of the show have always remained strong, though, and the rest of the episode simply does not match up.
Score: 8.2/10
