And oops, my bad, I mentioned back there that Natalie is the louder twin, when actually Nadiya is the louder one, whereas Natalie is a tad quieter, a seen in this episode's and last episode's Roadblock. I like how their bickering has been kept at a minimum after the first leg, unlike Ryan's crass comment deflating his Bland teammate at the pitstop, and Monstruous Trucker Man getting all snippy at his wife during the Detour and whining about how he should've done the Roadblock despite Kelley doing well enough.
I almost forgot the TwiNNies still have their Express Pass. If they keep performing this well and barring any bad luck with taxis or getting lost while driving, they could be able to keep it till the last leg it can be used so they can skip a task and whisk to the pitstop much quicker. Here's hoping.
