Brennan watches via video camera while Booth questions Ali about his affair with Mrs. Masruk. Booth gets assertive, and Ali asks to see an attorney. Just as things are heating up, another agent shows up and tells Ali that he's free to go. Booth asks what that was all about, and the other agent says that Ali works for Homeland Security, and was a mole in the Friendship League. They don't want Ali's cover blown. Booth tries to protest, and gets nowhere, so he hits the wall! Hard! Brennan gets all turned on, watching the whole thing from another room.
Brennan and Booth drive somewhere with horrible blue screen backgrounds flying by. Brennan doesn't want Booth to drive angry, and Booth denies that he's angry. But he's clearly angry that his investigation got tampered with by Homeland Security. Booth brings up the Serenity Prayer, which Brennan has never heard of, because she was raised in a hatch under a mysterious island. Brennan asks if he wants to talk about Tessa, and Booth wonders why she's so interested. Brennan offers up another topic: Booth's years as a sniper. Booth doesn't want to talk about that either. How about the weather? That's always popular. Can you believe how hot it was this summer? And what's up with all the hurricanes? Brennan promises that they'll find out who killed Masruk through science, because "you can always count on the dead."
Brennan returns to the lab, where she spends barely any time now that she's a pseudo-investigator type, and learns that they didn't find any evidence of known genetic disease. Jack shows her the bomb they reconstructed from trace evidence, "just for fun." And to show that they're smarter than the FBI. I hope that's a non-working bomb, because otherwise this show might get explosive! It might blow up in their faces! I'm sorry. Zack brings over the skull he reconstructed, and if they have a skull, I don't know why they couldn't use dental records to identify the body, but whatever. Brennan observes the skull and declares that the cracks in the bones were definitely caused by a toxin. The peeps scatter to start testing.
Angela finds Tessa at a café somewhere. God only knows how she found her, but let's just let it go, shall we? It's about the least offensive plot shortcut this week. Angela walks into the café and "accidentally" drops her bag right by Tessa's table, which leads to an animated conversation between the two that we don't hear.
