I'm not surprised. Every challenge with a puzzle the Villains blew them out of the water, and you saw with the Sumo wrestling challenge that physically, the heroes blow the Villains out of the water. Also, Boston Rob is a natural born leader; people listen to him, and he's organized. Who's the leader with the heroes? Up to now, it looks like James id the only one people keep backing. I love his competitiveness, I was lol'ing when he was yelling at people during the challenge... fucking guy was losing his voice. lol. Else from that though, the heroes don't have much going for them.
People are saying that JT is fucking himself over by flip-flopping, I don't think he is. It's the 2nd time in a row he's the deciding vote as to who leaves and who stays. That puts him in control of his own fate (until he pisses off everyone) and who gets taken out. When the merge hits, I expect him to be quite dangerous.
