The battle of the exiled secret was finally revealed in episode 9 of MTV's “The Challenge: Battle of the Exes 2” Tuesday. Just when the four remaining teams believed they were close to securing a spot in the final, host TJ Lavin made the shocking reveal. 

In a surprising visit to the dome ahead of the weekly challenge, Lavin told the remaining contestants that the eliminated teams had been competing in a secret losers bracket, the battle of the exiled. Ahead of the final challenge, Lavin brought in the remaining two exiled teams to compete against one another to earn a spot back in the game.

“Each week you guys send someone to the dome. Each week someone goes home, right? Well, or so you thought they went home,” Lavin said. “I’d like to welcome everybody to the battle of the exiled.”

“This changes everything!” contestant Sarah Rice said of the "Exes 2" twist.

After begin eliminated in episode 8, Zach and Jonna, returned to compete against the reigning exiled champions, Johnny "Bananas" and Nany. “The banana that you love to hate is back to set the record straight!” Johnny said. “We’re about to turn this place upside down, man!”

After competing in an intense game of “It Takes Two To Tangle,” Johnny and Nany were awarded the winners and earned a spot back in the house. Zach and Jonna were eliminated. “It came down to who had the most heart and who wanted it more,” Johnny said.

After the tense elimination, the team reunited for the challenge "Wrecking Ball." Using dodgeballs and a traveling wrecking ball, the teams — which were suspended 30 feet in the air — had to knock their opponents into the water. The first team to fall off the platform would earn a one-way ticket to the dome.

Due to their differences with just about every other member of the show, Wes and Theresa were immediately targeted in the game. After trying to combat a steam of dodgeballs, the pair were the first couple to fall and therefore, earned a spot in the dome. Jordan and Sarah ultimately walked away as the challenge winners and earned the title of the power couple.

In an effort to make their potential spot in the final easier, Jordan and Sarah decided to keep "Real World: Ex-Plosion" newcomers Jay and Jenna in the game, sending Nia and Leroy into the dome against Wes and Theresa.Unfortunately for the house, Nia didn't take the news that she would be competitng in the dome well.

The rest of her reaction to Jordan and Sarah's betrayal, and her impending fight with Nany, will be shown in episode 10. Catch “The Challenge: Battle of the Exes 2” Tuesdays at 11 p.m. EST on MTV.
