The couples have for the most part not found themselves arguing too much on the special dating edition of The Amazing Race, but that could all finally change.

Lebya and CJ Knew They Were Going To Be Eliminated

In a preview clip for the March 6 episode, titled #MurphysLaw, the fact that the blind date couples didn't know each other ahead of meeting at the starting line starts to take its toll on some of the partnerships-specifically, that of Hayley and Blair.

The doctor and nurse have been the one blind date couple staying at the back of the pack thus far, and now, it seems like they may finally be done playing nice with one another after a potentially mistake costs them the ability to finally get ahead.

Jeff & Lyda Admit To Making Mistakes

"Don't listen to me. What do I know?" Hayley says in the clip as she and Blair prepare to zip line across a jungle for a challenge.

And of course, when the teams all arrive at the finish line, Phil wants to know if they're finding romance-but they could be upstaged when one of the dating couples potentially takes their relationship to the next level officially.

"And someone's getting engaged! Who is it?" a voiceover asks in the clip.

Regardless of who gets engaged, overall it could be the most shocking and surprising leg yet of the season-especially when a team no one expected to see going home early may find themselves eliminated at the Starting Line.

"That was the shockingest shock of all shocks," Jonathon says in the clip.

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