As Bones nears its season 9 finale, there will be many big developments that could shape the future of the show, especially for Booth (David Boreanaz).

Booth & Brennan Go Down 'The Rabbit Hole' in Season Finale of Bones?

Fox released a plot synopsis this week for the season 9 finale of Bones, which is titled The Recluse in the Recliner. According to the synopsis, the final episode of season 9 will be a huge one for Booth, as someone he has been communicating with dies suddenly.

The Jeffersonian team will investigate the death of Wesley Foster, "a conspiracy blog writer who had arranged to meet up with Booth to discuss a previous case before his untimely death," the synopsis reads.

The team soon realizes that Foster's murderer did not want him talking to Booth and they must "figure out who is behind the death and how the previous case is relevant."

As the case goes deeper and deeper, Booth soon realizes that he may be in over his head, and it may actually put his career at the FBI in question.

As Enstars previously reported, this finale will end in a cliffhanger. Could this mean that Booth is forced to retire from the FBI? Is is still unknown at this time.

In the mean time, Bones fans still have one more fun episode to get through before the pulse-pounding season finale. In the next episode of Bones, the team is investigating the death of a swim coach leading a double life as a drag queen, and the case leads Sweets (John Francis Daley) to come in contact with "a plethora of drag queens," executive producer Stephen Nathan told E! Online recently.

Sweets is dealing with some office politics as well when Jessica (Laura Spencer), the new intern, comes in and causes some problems with him.

"Immediately there's tension between her and Sweets," Nathan said.

Bones season 9 airs Mondays at 8 p.m. on Fox.
