The Challenge - Season 19 (2010)

Is it Team Wes or Team Kenny? Alliances are split between the two rivals, and a secret mole flies under the radar making one alliance stronger.

What would have been THE most underhanded move to date is foiled when an injury takes one team out of the competition. Will Kenny find out there's a traitor in his midst?

Things get ugly when the competition turns best friends Danny and Wes against each other. And the Exile threatens to break up a budding romance.

In an effort to protect himself from exile, Wes offers up two members of his own alliance. Will this betrayal ultimately lead to his downfall?

A major power shift sends two unlikely teams into exile, permanently changing the course of the competition. And Ev calls out Wes on his relationship with Theresa.

With Wes gone, Evelyn stands alone. But she continues to wheel and deal, hoping to save her team from what might be the toughest exile yet.

It's the last Challenge before the final competition, and the stakes are high. But no one expects the game twist that will determine which two teams are sent to the final Exile.

It's down to the final four with $300,000 on the line...and a mountain between the challengers and the cash.

The cast sits down with Maria Menounos to discuss their experiences on the season.
