Teen Wolf Season 6 episode 5 spoilers: Peter and Stiles team up; what's Malia's dad been up to?

Stiles left a major clue of his existence before he was taken away by the Ghost Riders, and Season 6 episode 5 of Teen Wolf will see the gang – Scott, Lydia and Malia – connecting Stiles to his Jeep.

The past few episodes of Teen Wolf saw the gang realising that there was yet another person in their team, but they were unable to remember who it was. This Tuesday's episode saw Lydia searching for clues in the Stilinski residence, but Claudia proved to be a hurdle, and this has once again given traction to the theory that she is working with the Ghost Riders. The episode also saw Melissa giving Lydia access to Claudia's medical files and commenting that it's a miracle that Stiles's mom is still alive, as she has been suffering from dementia for the past 10 years.

Meanwhile, the promo for next week's episode showed Stiles teaming up with Peter Hale, who has also been kidnapped by the Ghost Riders, to find a way to return to their friends in Beacon Hills. We last saw Ian Bohen's character Peter in Season 4 of Teen Wolf when he locked up in Valack's cell. It is not immediately known how he escaped and why he was targeted by the Ghost Riders.

Showrunner Jeff Davis had hinted at Peter's return, telling Entertainment Weekly that Season 6 will explore a bit of Peter's backstory. "You'll see," he said. "We definitely do a bit of a flashback to show exactly what happened to Peter."

The synopsis for Season 6 episode 5 titled Radio Silence reads: "Stiles reunites with an unexpected ally; and Scott, Lydia and Malia connect Stiles' Jeep to his disappearance."

Teen Wolf airs Tuesdays on MTV.
