<P> The series was renewed for a tenth season on January 29, 2014 . Series creator Hart Hanson stepped down as showrunner for the tenth season to focus on his new TV series, Backstrom; longtime executive producer and writer Stephan Nathan took over the role of showrunner . In January 2014, Fox Entertainment President Kevin Reilly commented that season 10 would possibly be the final season, but in July 2014, Fox chairman and CEO Peter Rice commented, "I hope it's not the last year...it's a fantastic series, it's famously moved all over our schedule for 10 years...It's (Emily Deschanel and David Boreanaz's) last year contractually, so we have to have that conversation...but I hope that they will come back ." The tenth season features the series' 200th episode, written by Stephen Nathan and directed by series star David Boreanaz, which is an Alfred Hitchcock homage set in the 1950s . </P> <P> In July 2014, John Boyd was cast in a recurring role of James Aubrey, a junior FBI agent working under Booth . However, it was later revealed that Boyd would be a series regular . The character of Lance Sweets, portrayed by John Francis Daley who joined the cast in the third season, is killed off in the season premiere episode . The decision to kill off the character was because Daley needed a break from the series to direct the upcoming National Lampoon's Vacation remake, Vacation, and executive producer Stephan Nathan thought killing off the character instead of just writing him off would be more impactful . With the series' 206th episode, Bones became the longest - running one - hour drama for producing studio 20th Century Fox Television, and the episode also names all 206 bones in the human body . Emily Deschanel's real - life pregnancy was written into the show (like her first pregnancy), and the season features the reveal that Brennan is pregnant with her and Booth's second child . The season finale was written as a potential series finale, as it was written before the writers knew the series was renewed for another season . </P> <Table> <Tr> <Th> No . overall </Th> <Th> No. in season </Th> <Th> Title </Th> <Th> Directed by </Th> <Th> Written by </Th> <Th> Original air date </Th> <Th> Prod . code </Th> <Th> US viewers (millions) </Th> </Tr> <Tr> <Th> 191 </Th> <Td> </Td> <Td> "The Conspiracy in the Corpse" </Td> <Td> Ian Toynton </Td> <Td> Stephen Nathan & Jonathan Collier </Td> <Td> September 25, 2014 (2014 - 09 - 25) </Td> <Td> AAKY01 </Td> <Td> 6.34 </Td> </Tr> <Tr> <Td_colspan="8"> The team attempt to find the identities of the people responsible for framing Booth and sending him to prison .
