It's already been confirmed that Jared Booth will return to Bones on season five.
The actor that plays this character, Brendan Fehr, was recently asked about his status and told E! News that he isn't sure about the duration of his stay on the show.
"As far as I'm told, I will be back. I don't know how many episodes. I don't know in what capacity or anything like that, but I have been told that I can expect a little bit of employment in the upcoming season," Fehr said.
Considering that his brother is in recovery, the actor would love to see Jared fill in for him on a case, or perhaps even attempt to sweep Bones off her feet again.
"I suppose he does stand a chance [with her]. He's a fairly handsome guy, but ultimately it's Seeley and Bones' deal."
