Even though Booth and Brennan have gotten married on “Bones,” the excitement of Season 9 is not over yet. Proof of this can be seen in the most recent casting: Richard Schiff (“The West Wing”) and McKayla Maroney (the meme-friendly gymnast) will both guest-star in an upcoming episode.

According to EW.com, both guests will appear in an episode focusing on the murder of a physicist’s daughter, Amanda. Schiff will play Dr. Leon Watters, the “Brennan of theoretical physics.” After his daughter dies, the man becomes detached — but Brennan (Emily Deschanel), seeing herself in the scientific genius, understands that Watters has to focus on work in order to be able to cope with the situation.

Considering Brennan is a parent of a daughter herself, it’s possible that this will be a very poignant situation for her.

Maroney, a medal-winning gymnast at the 2012 Olympics, will play Ellie. She is described as both a friend and a rival to Watters’ deceased daughter.

While at some point, “Bones” is expected to move to Fridays, for now the show airs Mondays at 8 p.m. on FOX. The next episode — focusing on Booth and Brennan’s honeymoon — airs Monday, Nov. 4.
