Above all, both characters will need to come to terms with the realization that they were making the right choice when deciding to leave their jobs at the FBI, but it was the right choice for the time being only – the situation is going to change in the future and emotions are going to start pouring in at some point.
Other than that, the characters will have to face certain events from their past that have been haunting them for a while, and they will need to realize that they can’t run away from the past forever. This will be particularly valid for one character, according to rumors, but we have no idea which of the two.
New characters might join the show’s cast as well, although those are just rumors at the moment and we have no idea what’s being prepared on that front.
Some reports claim that Betty White has been added to the cast as a new character that will lend the team a hand in solving their more difficult cases, and there have been other rumors about new characters as well. But at least for a while, the show is going to focus on developing the personalities of Booth and Brennan in even more detail, and exploring the more interesting sides of their personalities.
