Theo Raekan (Cody Christian) will make his grand return when "Teen Wolf" comes back from hiatus in January, and we might just be seeing a softer side to him.

"I will say that there is a different side to this character that they haven’t seen, the audience hasn’t seen," Christian says. "And maybe even he hasn’t seen. It’s really cool, there’s like this sense of vulnerability. Whether or not he’s going to allow himself to show that side is [another] story..."

While we can't reveal how or when Theo will be making his way back to Beacon Hills, we can reveal that he'll be an integral part of the pack's mission to find and remember Stiles (Dylan O'Brien), who is still trapped in the Ghost Riders' phantom train station.

"I think Theo’s going to be this necessary evil, where they don’t really want his help, but I think he has information that they’re going to need," Christian says.

Obviously Scott (Tyler Posey) and the pack should cover all their bases and set up about a million failsafes if they're ever going to trust Theo again -- but according to Christian, Theo might have actually learned his lesson after failing to steal The Beast's power and become an all-powerful alpha.

"We’re looking at like a changed guy here," he says. "Someone who lost the game he thought he was going to win. There’s a sense of humility to him now, and I dig it. It was fun."

We'll find out whether or not Theo's actually changed soon enough -- but we're still hoping Scott sleeps with one eye open, with a guy like Theo lurking around town.

"Teen Wolf" returns Jan. 3, 2017 at 9 p.m. ET/PT on MTV.
