The Challenge

The competitors get a glimpse of their rivals, Cory is out for Bananas's blood, Rogan's lingering health issues catch up to him, and the sensuous Spanish air inspires romance.

Cory roots for Alicia during the Who's Got Balls challenge, Cara Maria shows little remorse for hooking up with Kyle shortly after Marie, and TJ introduces Grenades to the challengers.

Nelson uses his Grenade against a strong competitor, Melissa gets into trouble but luckily has Nicole to comfort her, and Natalie's strategy of forming alliances rustles feathers.

Kayleigh and Nelson can't stop flirting with each other, Marie rubs Brad the wrong way and makes herself a new vendetta, and one competitor eats his way to victory during Food Wars.

Two members of a vulnerable team take advantage of another player's illness, and tensions between Melissa and Kam reach a boiling point.

Someone leaves notes in one of the women's rooms, causing speculation and distrust between them, Shane gets flirty with Victor, and Bananas uses an unusual approach during the Inquisition.

The person who's leaving notes is revealed, one competitor gets too sick to compete, and TJ introduces the Mercenaries.

The Mercenaries give the competitors a run for their money in Crazy 8, the Car Crash challenge proves dangerous for one player, and Cara Maria becomes suspicious of a rookie's moves.

TJ disapproves of a competitor giving up during a challenge, alliances between women start falling apart, and Kayleigh surprises everyone by thinking for herself during an elimination.

Devin spills the tea about a secret hookup in the house that shatters alliances and tests loyalties, Natalie and Nelson form a new bond, and TJ makes it clear he doesn't condone bullying.

A competitor is shocked after being betrayed, setting off another betrayal at the hands of the Troika, and TJ brings back four Mercenaries to make the double elimination even harder.

Natalie makes a last-ditch effort to appease Nelson and make amends for past actions, and TJ announces where survivors of the upcoming double elimination will head for the final challenge.

A member of the Troika punishes a competitor for being verbally aggressive during the Inquisition and sends him off to the elimination, and new vendettas are formed leading up to the final.

TJ reintroduces two Mercenaries with the power to launch a grenade if they win a card game against the final challengers, and a twist makes the final winner-take-all.
