Body parts are found in various fishes in an aquarium, sending the Brennan and Hodgins into the aquarium filled with sharks. The case was kind of bland after that and didn't have any real twists other than the revelation of the lion fish as the murder weapon. In the end, the victim, Jazz Gunn, was found to be killed by a fourth-grade teacher who had been duped by him into thinking that being around fish could cure her fibromyalgia.
As for the burgeoning romances between Booth and Dr. Bryar and Brennan and Andrew, I could care less. The romantic side of relationships are always done in the more transparent way. Hart Hanson has an idea of what he's doing, but it's so obvious it's hard not to laugh. Clearly, the only reason for Bryar and Andrew is for Brennan to realize she has feelings for Booth. There is no other way to go.
I have to say, Dr. Bryar, played by Rena Sofer, is much more pleasant than M. Allison Hart, Sofer's character on NCIS, also a romantic interest for the male lead, Gibbs.
Score: 8.7/10
