Betty White returns as Dr. Beth Mayer in “Bones” Season 12, episode 10. Patrick McElhenney/Fox

“Bones” premiered a fun, action-packed episode this week on Fox. Booth (David Boreanaz), Brennan (Emily Deschanel) and Aubrey (John Boyd) went undercover at a demolition derby in order to catch a killer. While they were solving the case, Dr. Gordon Wyatt (Stephen Fry) was busy examining Dr. Sweets’ notes on Zack (Eric Millegan).

Meanwhile, Hodgins (T.J. Thyne) tracked down a Masonic coffin that might contain the remains of Gormogon’s failed apprentice. It could help in proving Zack’s innocence.

What will happen next week in “Bones”?

According to the official synopsis, Betty White will return as Dr. Beth Mayer! The only other women in Washington, D.C. with more experience that Brennan in the field of forensic anthropology, Mayer returns in Season 12, episode 10 to help her. Bones seeks her guidance when she wants to know the meaning of passion in the work place.

While Brennan seeks Mayer’s guidance, Booth and Aubrey will be busy solving yet another grisly murder on their hands. The burning and bruised body of an aspiring writer and director crash lands into a passing car in episode 10. This leads the FBI to investigate a series of odd locations and characters that are connected to his film.

The preview of the upcoming episode, titled “The Radioactive Panthers In The Party,” shows Cam (Tamara Taylor) and Arastoo (Pej Vahdat) getting married! It seems like the two will tie the knot in this episode. However, something bad happens and Booth says that they must get everybody out of here. An explosion occurs and things don’t look too good for the Jeffersonian.

Interestingly, Booth lets Aubrey take the reins on the investigation this week. Is it because his back has been acting up of late?

Only three episodes are left for “Bones” to end. Season 12 consists of only 12 episodes.

Watch new episodes of “Bones” on Tuesdays at 9 p.m. EST on Fox.
