Poor Sweets. How hard it must've been for him to lose his parents, people who have given him safety and love in a short time.
It was very nice to see him interact with Gordon and exchange points of view. I loved that conversation he had with Sweets in the interrogation room, about his parents because he was right.
Bones interrogating the suspect was very funny. I liked that she wanted to be like Booth and tried to use his 'techniques'. I bet she must've looked very sexy to Booth! And Booth shooting that speaker was nice, considering that he had a reason now.
The last scene was very touching. Emily is an excellent actress, she really delivered. Her confession was very sad, but I was shocked by Booth's confession. It was nice of them to share that with Sweets. The connection Booth and Brennan have is amazingly shown here. Subtle but effective.
