Overall, I thought this was an excellent episode and an intense finale! I honestly think it's one of the best finales in the whole series. There was a lot going on in this episode so I had to watch it twice to catch everything.
The exploding body was grizzly but I thought it was interesting and ingenious that the guy kept all of his information on his nipple ring. Also, I know I've mentioned it before, but I just adore it when Booth calls Hodgins "bug boy".
One of the lighter parts of the episode and also the funniest part was when Fisher finally realized that life is beautiful and that murder is bad. I thought it was hilarious when he kept says things like "bastards" and "sons of bitches" when referring to the murderers. And it got better when later Brennan corrected herself from saying "assailants" to "bastards" for Fisher's benefit. Awesome!! The old Brennan might have chastised him for his language.
It was ironic that at the beginning Booth made the comment to Brennan that they have a beautiful home, but in the end it was destroyed in the gunfight. I loved those scenes where Booth is arming the house with guns and explosives, it was very A-Team-ish. HAHA! I thought it was very creative to hide the explosives in potted plants and in picture frames. The shoot-out was super intense and I love that Brennan was able to come in to save Booth's life and take out a bad guy in the process. It was impressive that even though he was shot multiple times, Booth still had the energy to break the other guy's neck. I'm not sure who is behind trying to kill Booth but for some reason I think that deputy director Stark has something to do with it. If Booth didn't trust him enough to give him the details of the case then I don't trust him either.
I was thinking along the same lines as Hana at the end when I thought that maybe Booth was paralyzed or something, but I'm glad I was wrong. It was completely unexpected that he would be arrested for murdering the agents that attacked and tried to kill him! I admit that it brought a slight tear to my eye when the other agents were taking Brennan away in the end. I can't wait until the Fall!!!
