Fans of Teen Wolf saw Cody Christian in the trailer for season five of the popular supernatural television series, however, his role in the promotional trailer gave no indication of what exactly his role will be in season five.

The cast of the show spoke to Hollywood Life to give fans an idea of who Theo is, and what he is doing in the town.

During the ATX TV Festival in Texas, Tyler Posey offered his opinions about Christian's character, stating, "I think there's a lot of depth to his character."

However, this depth may not necessarily be a good thing, especially when it comes to the pact. Scott, played by Posey, will take Theo, Christian's character, in as one of his own.

He will attempt to get Stiles, played by Dylan O'Brien, on board, although it will not be easy, as Stiles does not trust Theo.

Likely, fans can expect a bit of tension between Theo and Stiles and possibly even Scott and Stiles.

Scott has a history of accepting others with open arms, while Stiles is much more wary when it comes to strangers.

Also, Theo does not turn out to be exactly who he says he is, so this definitely will complicate things as the season unfolds.

"Jeff [Davis] and the producers have been teasing this is going to be our darkest season yet, but I think it's going to be our goriest season," said Posey. "It reminds me of Saw! It's going to be so gory -- you're going to freak out."
