They've so far been doing a good job of dominating the competition so far, but Bangkok could prove to be the turning point for the blind date couples on The Amazing Race.

Matt & Ashley Dish On Their Engagement In Phuket

In a preview clip for the March 13 episode, The Great Amazing Nasty Race, blind date couples Jelani and Jenny and Hayley and Blair in particular, seem to be having the most troubles as they try to navigate through the chaotic city.

"The blind daters are unraveling," a voiceover teases in the clip. "It's going to take more than a Zen experience and some cute cats to conquer to this leg."

Tensions Begin Surfacing In Phuket

Jenny and Jelani, who previously placed first twice and placed third on the previous leg, seem to have some major issues specifically regarding their travel in the city-and the frustrations could cause them to have problems in their communication for the first time.

"The mopeds are way faster than us," Jenny mumbles in the clip.

And after Jelani makes a potential mistake during a task, Jenny begins to rip into him as well.

"Can you just think?" she yells.

Meanwhile, the communication problems between Hayley and Blair continue to come between them as well, as it appears that Blair continues to frustrate his date by not listening to her when she suggests doing something a little differently.

"Whatever I say, I feel like you're not going to listen," Hayley says to Blair.

Unfortunately, Blair may still not listen-and it could prove to be their downfall.

"Let's run right past it!" Hayley yells after him as he potentially passes the destination they are seeking.

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