I like them. They kind of have a Colin & Christie thing going on with them, both in racing skill and in me wondering "What kind of stuff is getting left out?" Such as when Diana makes a complaint about Justin and we're supposed to think "Ooooh she's had enough of him", but then for a split second before the camera cuts she has a huge grin on her face. I can tell there's more to them then what's being shown and I'd like to know the "real" them, not the "10 total minutes of screen time with very obviously not from that moment insults" them. I know your games, Amazing Race editors, you can't fool me with your soundbites that have a completely different tone and are coincidentally when the people are off screen or facing away from the camera.
Of course since I like them they won't win. They'll probably place second or something, just to get my hopes up. (I didn't just spoil you, I don't read those.)
