When the "Criminal Minds" season 10 returns for episode 11, frozen bodies will litter Nevada's waters as spoilers hinted that JJ's terrorist kidnapper back in season 9 will make an appearance.

"Melrose Place" alum Grant Show will play Colton Grant, the cult leader responsible for all the murders. Not much is known about the cult leader's background, however.

The synopsis offers plenty of episode 11 spoilers for "Criminal Minds" season 10 as it reads: "When frozen bodies are found in Nevada floating in water, the BAU's investigation leads them to suspect that the victims were part of a cult that could be behind the deaths. Also, JJ (A.J. Cook) confronts old demons from her abduction and torture last year."

Faran Tahir will reprise his role as Tivon Askari, the abductor of JJ in the episode titled "The Forever People."

But Celebeat said that Faran Tahir might only appear through flashbacks because the fans watched the terrorist die after he was shot by Thomas Gibson's Aaron Hotchner.

Erica Messer hinted as much spoilers for "Criminal Minds" season 10 in an interview with TV Guide as she said that Spencer Reid (Matthew Gray Gubler) will be the "sounding board" for JJ's post-traumatic stress syndrome as a result of her abduction.

"I've always loved their friendship and this will bring them closer together," she said. "Emotionally he's going to be so invested in JJ's story."

The other guests for "Criminal Minds" season 10 episode 11 include: Dion Mucciacito, Brian Gant, Ross Mackenzie, Ptolemy Slocum, Travis Lincoln Cox, Amanda Serra, Kristy Johnson, Max Potesky, Angelina Ganiere, Christina Edland, Rachel Parker and Nicholas Keenan.

"The Forever People" is written by Breen Frazier and helmed by Tawnia McKiernan.

Watch out for more "Criminal Minds" season 10, episode 11 spoilers ahead of the airing date on January 14 on CBS. Fans of the show can also look forward to the spinoff, which will start production in mid-February.
