Peter Hale (Ian Bohen) will return in the upcoming episode of "Teen Wolf." Instead of being the antagonist, he will find himself helping Stiles (Dylan O'Brien) escape the Ghost Riders.

In the episode titled "Radio Silence," the synopsis (as per TV Guide) reveals that Scott (Tyler Posey), Malia (Shelley Hennig) and Lydia (Holland Roden) have yet to fully remember who the missing person is. The trio have been steadily finding clues to help them, even interviewing Stiles' grandfather, but Stiles' identity still remains hazy. This time around, they will hit pay dirt when they recognize his Jeep. Will this be the hint they need to get their memories of him back?

Meanwhile, Stiles is forced to rely on his skills to remain alive. The Ghost Riders are very close to fulfilling their mission to erase his existence. Stiles will find himself forming an alliance with someone unexpected. Peter is also a victim of the creatures. To stay alive, he must work with Stiles and let bygones be bygones.

Fans of the series can remember Peter as the frustrated Alpha who started the pack. He and Scott are sworn enemies. Executive producer Jeff Davis previously talked about Peter and Stiles' reunion in season 6.

"They need to help each other. They need to get out. They essentially need to be remembered. They both realize they've been forgotten and they no longer exist. There's a very interesting scientific element to it that the younger characters sort of get into — Liam, Mason and Hayden. It's in the fist few episodes, where it's all within the realm of possible worlds. Can you be forgotten? Can your life divert into this one path as if you never existed? Stiles and Peter have to help each other," the EP teased, according to the Hollywood Life.

"Teen Wolf" season 6 airs Tuesdays at 9 p.m. EST on MTV.
