Booth (David Boreanaz) will be dealing with his newfound mistrust for the FBI and other institutions he once trusted when Fox's Bones returns for Season 10.

With Booth in jail for shooting members of the Delta Force in the Season 9 finale, he will have had a lot of time to think about the conspiracy by the time Season 10 rolls around.

Bones showrunner Stephen Nathan spoke with TVLine about Booth's feelings regarding the various institutions he's respected so much over the years.

Nathan said the arc will "not be overwhelming," though "it's something he has to deal with. It's not as if he is in a rubber room, you know? It's a trauma that has shaken his trust in the people and the institutions that he took for granted. So it's just a matter of regaining that trust, and that's what he's dealing with."

It won't all be serious drama in the new season, however. Nathan revealed a few other plot lines that would take place in Season 10, including Booth and Brennan (Emily Deschanel) dressing up undercover for a crossword puzzle tournament as well as the trippy 200th episode, in which reality may be altered slightly.

"They are going to be undercover at a crossword puzzle tournament," Nathan said. When asked if that meant they would be taking on new aliases, Nathan replied, "That remains to be seen, but I'm smelling new [personas]."

Meanwhile, the 200th episode will be exploring "what Booth and Brennan might have been like in another world," saying that it will be like "going for a ride at an amusement park."

Bones Season 10 is set to begin Thursday, Sept. 25 at 8 p.m. on Fox.
