The competition in “the Biggest Loser Pinoy Edition has just gotten more complicated and tense as the contestant pairs formed alliances to remain in the camp and have a bigger chance at reaching the finale.

Du brothers Ralph and Christian have teamed up with showbiz royalties Pat and Cathy to devise tactics with their diet and workouts in hopes of having the upper hand on siblings Ikya and Bryan, bagong bigateam Osie and Francis, and Kayen.

This strategy might potentially change the game after the program revealed a surprising twist in which the Du Brothers have to face off with the rest of the bigating doubles in their camp challenges and the next competitive weigh-in.

If the Du brothers win in the weigh-in, they will get to decide who will exit the camp. But if they lose, one of them will be sent home packing.

To what lengths will the Du brothers go in order to outlast the other contestants? Will the showbiz royalties be safe from elimination this week because of their allegiance with the Du brothers? How will this affect the bigating doubles’ relationship? Will Kayen remain strong enough to carry on after her husband Carl left the camp?
