U-Turning Dave and Connor while in Orvieto could prove to have been a fatal mistake for Big Brother newlyweds Brendon Villegas and Rachel Reilly on The Amazing Race: All-Stars.

Dave & Connor U-Turned Because Of Threat To 'Brenchel?'

The decision to U-turn the father/son cancer survivors in the last leg has resulted in the team being alienated from the rest, and in a preview clip for the Sunday, April 27 episode, the competition will heat up between them and the other teams as a result.

"It's us three and them," Jamal Zadran says in the clip as his teammate and cousin Leo Temory, country singers Jen Wayne and Caroline Cutbirth, and Dave and Connor all sit together on a train.

Alliances Up The Level Of Competition?

The three teams are seen putting their hands in together, in a move signifying an alliance against the newlywed couple, as well as making fun of Rachel's signature crying maneuvers in her first appearance on the show back in season 20.

"None of the other teams even stop to talk to me," Dave is seen saying in the clip as he pretends to cry. "They all hate me."

Despite the drama, the couple doesn't appear worried that about a three-way alliance being formed against them.

"We're here to kick some butt, we're taking some names and we're here to win a million dollars," Villegas says. "If you couldn't handle it you shouldn't be on the race."

"I don't think we really have any friends right now, but that's okay, we're used to it," Reilly added.

The only team that doesn't appear to be wrapped up in the tension is Cowboy brothers Jet and Cord McCoy.

It is unclear where teams will head for the new leg, or what tasks they will complete, as the preview appears to be focused on the rising tensions.

Though the alliance could help eliminate Brenchel, it has been previously reported that they are among the final three teams in the race. Dave and Connor are rumored to be the winners, with the country singers placing second and Brenchel finishing third. It is unclear however if this is how the race does truly finish.

The Amazing Race airs Sundays at 8 p.m. on CBS.
