When we last saw Bones, the surgery to remove Booth's (David Boreanaz) brain tumor was a success though Booth reacted poorly to the anesthesia which resulted in a coma that lasted four days. When he woke up, we learned that Booth's memory was shattered, leaving Brennan (Emily Deschanel) shocked that her close friend and partner of four years cannot remember her. Since Bones has been renewed for two more seasons, it's safe to assume that Booth will eventually recover from his brain injury. However, the road ahead won't be easy.
"It's an interesting thing that's going to happen," Boreanaz said Friday when the summer TV press tour visited the set of Bones. "What I really want to maintain with the arc with him ... is that he does have a remembrance of certain things, but he's not as adept at other things as he thought he was."
There are plenty of things Booth won't remember this season, including his distinct approach when it comes cross-examining people.
"Whether it's knowing how to interrogate someone, and he doesn't do a certain thing and [Brennan is] looking at me going, 'This is what you usually do,' and I'm just a tad slow on that -- those are the little nuances they kind of discover," Boreanaz said.
But more importantly, Booth's inability to remember will take a toll on his relationship with Brennan, who previously asked for his semen in hopes of having a child.
"It makes me want to reinviest my time and energy into that relationship," Boreanaz added. "Because I don't remember certain things, now we're back to ground zero."
Fans can catch the fifth season on Bones on Thursday, September 17on FOX.
