The next big serial killer on Bones season 9 may be coming soon, according to new spoilers.

The new serial killer after Pelant (Andrew Leeds) will be much more silent and secretive than his predecessor.

"We will not know whether or not we are meeting the person when we see the episode," Nathan told TV Guide recently. Brennan (Emily Deschanel) will definitely be keeping her eyes open for him, though.

"[Pelant's warning] is in the back of Brennan's mind," Deschanel explained to TV Guide. "Where she has doubts is whether, when Pelant died, their hopes of solving those murders died with him. I think she fears it did."

Nathan added that viewers will see Pelant again on Bones, which is somewhat impossible considering he died earlier in the season, however the appearance may be a hallucination on Brennan's part.

In other Bones spoiler news, Fox recently released a synopsis for a December episode which guest stars Olympic gymnast McKayla Maroney.

In the episode, titled The Spark in the Park, the Jeffersonian team will be investigating the murder of a prominent gymnast. All evidence lead to a fellow gymnast (Maroney), but it is soon discovered that the murdered gymnast led a double life. Meanwhile, Booth gets angry at Brennan when she grows attached to the victim's father (guest star Richard Schiff). This episode will air Friday, Dec. 6 on Fox.

Will Zooey Deschanel Appear on Bones?

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