On tomorrow night's episode of Bones, The Gravedigger goes on trial.
It's a huge development and fans can get an early look at "The Boy with the Answer" via these episode stills.
But many viewers want to look ahead to the May 20 season finale - and, hey, who are we to disappoint them?
According to executive producer Hart Hanson, "The Beginning in the End" will be a major step in the evolution Booth and Bones' relationship, one as significant as the controversial events from the 100th episode.
"The season finale is a good place and a natural place to change the direction of a series, and [in the] fifth season, you've got to do that," Hanson told TV Guide.
Adds Emily Deschanel, who plays Brennan and is pictured above in a scene from the fifth season finale:
"Huge things happen in the episode, and that does change the course of everyone. But it's funny how subtle things can change people."
Fox isn't giving too much away. In its description of "The Beginning in the End," the network simply says: Brennan helps Booth make a difficult decision.
Got any theories on what that might entail? We'd love to hear them!
