Teen Wolf Sneak Peek: Stiles Is Finally Back -- And He's Made The Most Unlikely Ally Ever

You'll never guess who our favorite Stilinski just happened to run into

The good news: Stiles is finally back on Teen Wolf. The bad news: He's hanging out with the Hale we love to hate.

In a preview for next week's episode, below, the beloved Beacon Hills teen meets up with none other than Peter Hale, whom we haven't seen since he was locked up after trying to steal Scott's Alpha powers in Season 4. And get this: The two seem to be existing in some sort of weird parallel universe reminiscent of the Upside Down in Stranger Things (if the Upside Down were indeed an old train station).

But is having Malia's old man around all that bad? Maybe not, since the former Alpha seems to know a thing or two about the Ghost Riders and their Wild Hunt.

"They ride the lightning," he tells Stiles the clip. "They are an unstoppable force of nature, but I promise you, they don't make pit stops in train stations. If this is the Wild Hunt, there is no escape. You and I are doomed to ride the storm forever."

But what does Stiles think about Peter's gloomy assessment of the situation? Watch the clip to find out, and see it all go down Tuesday at 9/8c. (You won't want to miss this ep — trust us.)
