Good episode, with several plot twists and turns.
I think the best storylines allow Booth and Brennan to explore their individual areas of expertise. With that said, I wish they didn't always put Brennan in a vacuum. (Ex: She knows who Cindy Lauper is, but has never heard of American idol?) I also like that we get to know a little bit more about the interns, such as Zack Addy's singing background. The storylines in the background can be just as interesting as a storylines of the main actors.
However, did anyone catch the funny way David B (Booth) says "Ohio"? (Time code 36:01) when he is interrogating the gym owner. He says you were going to "oh hi oh." No one says it that way...๐๐๐
