Here are the top 5 things to know about the episode.
While Pelant has previously focused his targeting on Brennan, the Season 8 finale will have the target shift a bit to Booth and the FBI. The fact that Booth shot Pelant when last the two men met may have something to do with the villain’s new focus.
2. Brennan’s worry for Booth will lead her to reevaluate her relationship priorities.
“[Pelant] really forces her to look at her life and herself and her relationship and why she feels certain ways about certain things and makes her question some of her core beliefs,” Deschanel said. “It’s a very pivotal time for her.”
3. The return of Pelant may bring about some forward movement in the Booth-Brennan relationship.
Over the past season, not much has changed between Booth and Brennan. They’re living together and they have a baby, but we’re still waiting to see if this will lead to marriage or something else. The Season 8 finale — and the return of Christopher Pelant — may change that. “She realizes that, you know, Pelant could get him. Booth is in danger,” Deschanel explained. “Feeling Booth’s mortality and the possibility of him being in danger, and the concept of even living without him, kind of brings things to a forefront with Brennan.”
4. We can expect multiple murder victims.
It starts with just one FBI agent, but it sounds like Pelant isn’t going to stop there. Instead, several of Booth’s colleagues could be doomed before the episode ends.
5. How far will Brennan go to protect a loved one?
Dr. Brennan just likes her intern, Arastoo Vaziri, but she was willing to stick a hypodermic needle (allegedly filled with a deadly disease) into a criminal to save his life. So what would she do when someone she loves — like Booth — is in danger? “Brennan is willing to go farther than she’s ever gone to protect somebody that she loves,” Emily Deschanel said. “I think there’s really no bounds to her protecting.”
The “Bones” Season 8 finale, “The Secret in the Siege,” airs on Monday, April 29 at 8pm on FOX.
