Scott (Tyler Posey) and his pack will set up an elaborate heist to reveal the Beast's identity once and for all in the upcoming episode of the MTV series "Teen Wolf."

In "A Credible Threat," TV.com reports that the wolf brothers will use a charity game, lacrosse, to flush out the monster that arouses terror in Beacon Hills. Until now, Scott is no nearer to revealing the Beast's true identity.

The last clue that they got about the monster was when they were aiding Lydia (Holland Roden) to escape from Eichen House. The huge paw prints of the creature turned into rubber shoe prints, which indicates it is definitely human before the transformation.

For fans of the hit MTV series, the lack of clues on the Beast is a constant source of disappointment. So far, the signs point out to the monster being a chimera, but it is still not included in Theo's (Cody Christian) pack. Most likely, its human form is not even aware that he or she is the creature that all the supernatural packs have been giving a wide berth ever since it appeared.

Zap2it is conducting a poll on whom the fans believe is the Beast. Currently, Mason (Khylin Rhambo), Liam's (Dylan Sprayberry) best buddy, is on the lead.

When Mason was first introduced in the fourth episode of season 4, he was just an ordinary high school student, human and ignorant about the supernatural world. He was fascinated when he learned that Liam is a werewolf. Soon after, he was helping Scott with menial issues. Currently, he is the one who is convincing Liam to return to the pack and make peace with the Alpha.

Meanwhile, the title of the episode for the season finale has already been released, and it looks like it will be a huge showdown between the two packs in Beacon Hills, the wolves and the chimeras.

At the moment, Scott is still on a mission to bring his brothers back together, while Theo has been training his for the brewing war. The final episode simply labelled as "The Pack" seems to suggest that only one group will be left standing in the end. Which pack will prevail?

"Teen Wolf" season 5 airs Tuesdays at 9 p.m. EST on MTV.
