Alison announces that the current teams will be dissolved. The Unknowns will compete as a group as the Red team; the Ranch team will compete as a group and chose Black shirts (over Blue).

With the episode being the final one before Valentine’s Day, the first challenge was a temptation involving chocolate. Each player would be allowed to eat as many chocolate pieces as s/he wished, the player eating the most would have the power to (if he/she desired) switch up to two players from his/her team for the same number from the other team. Further, the winner would remain a secret – Alison will announce only the player’s decision. Alison announces that the winner chose to swap Jay and Jen (Black to Red) for Sarah and Deni (Red to Black). Arthur (who ate 35 pieces) admitted he did it; he stated that he distrusted Jay and Jen from week one, and thought Sarah and Deni would be voted off the following two weeks, thus protecting him and Jesse. However, the decision causes a huge rift among the Black team; Bob and Jillian believe that Arthur hurt his cause by making the Black team weaker overall.

Both teams and all four trainers were featured trying to compete for space in the Ranch gym.

The second challenge featured contests in five disciplines: endurance, speed, agility, strength, and knowledge. The winning team would receive videos from home. After the teams chose their players for each discipline (the last one would have only one player), Alison announced that the disciplines were not what everyone thought:

* Endurance involved enduring direction from a teammate – one player would have to roll a rock uphill, blindfolded, taking direction only from his/her partner.
* Speed involved how fast a pair could stack bricks to a six-foot height and keep the stack stable for five seconds.
* Agility involved how quickly a pair could arrange five dishes, from lowest to highest in terms of caloric content.
* Strength involved a balance of how quickly a pair could carry each end of a log while balancing on a telephone pole (if a player fell off, they would have to restart from the beginning).
* Knowledge involved the heart – one player would have to shoot an arrow through a heart.

After the fifth discipline, a final task would be revealed (it would be completing a heart-shaped jigsaw puzzle).

Black won all five disciplines and the final task handily (Red had trouble with the Agility discipline). Black invited Bob and Jillian to watch the videos (for Deni it was special since she missed her daughter’s wedding to participate on the show). Brett discusses healthy cereals with Red team, plugging General Mills whole grain brands.

The last chance workout was not shown (Cara would appear at the weigh-in with a broken finger).

At the weigh-in the Red team went first. Jay and Jen both lost 14 pounds each (4.23%), (6.03%), Austin lost 10 (3.06%), Ken also lost 14 (4.36%). Q lost 7 (1.81%) and made excuses for his performance. Rulon lost 12 (3.04%) while Justin lost 10 (3.42%); neither was happy which upset Brett and Cara (thinking that, as the leaders of the Red team, they should celebrate small victories). Kaylee lost five pounds (2.56%). Moses needed to lose 11 pounds (3.13%) to become the fastest contestant to lose 100 pounds (six weigh-ins); he lost exactly that amount. Red lost a total of 97 pounds or 3.43% total percentage.

Black needed to lose 78 pounds to beat Red’s percentage gain and remain safe. Deni lost 9 (4.28%) while Sarah lost 10 (4.50%). Arthur lost 9 (2.02%) and was very upset, believing that he would probably be sent home. Jesse lost 11 (4.28%), Courtney lost 10 (3.63%), and Marci lost 13 (6.50%) (falling below 200 pounds). Needing 15 pounds to win, Olivia loses 16 (7.14%). Alison declares the contest over, but Irene’s 12 (5.55%) and Hannah’s 9 (4.28%) are shown. Black defeated Red in both total pounds lost (99) and percentage (4.35%).

Alison announced that Jen (6.03%) was immune from being voted off. At the table, Jen and Jay both vote to send Q home. Q votes for Jay, but Ken, Moses, and Justin each vote to send Q home. At home, Q is now down to 345 pounds. He takes Larialmy to a gym for Valentine’s Day, promising that they will become a healthy couple.
