New caps give much more insight into this challenge, effectively ruling out several people as potential winners (at least Butch ad Heidi). The very start appears to be a race to dig paddles out of the sand. Butch and Matt seem to be fumbling over the same one, and Rob is shown waving one around, possibly having retrieved his first. Rob is later shown paddling in a one-person canoe. So in all the caps, Rob seems to be in the lead. Butch is shown standing on the riverbank, standing up, then flinging his arms up in defeat, with Heidi next to him. Heidi is shown crying, in about the same spot. But Matthew is shown in his strongman pose (which he has made when winning other challenges), most importantly, clutching a glass of wine/champagne. This is the type of physical challenge at which Matt should dominate, so it's curious that Rob seems to be doing fairly well.

About the only thing Matthew could logically sacrifice in this episode (apart from another pair of shoes), "so that others can be given the opportunity of a lifetime" is the chance for the family visit. This suggests that, after winning, he might allow others a chance at the prize. Since the title of the episode is "Sour Grapes," this would seem to argue against Jenna or Heidi being the beneficiaries of such a gesture, since the title describes their attitude towards the Coke they didn't win.

So who does get to go, then? Hard to say. One possibility is Christy, who missed out on the food in the last episode: Despite Probst's claim that the RC occurs after Rob and Jenna's argument, they are clearly fighting on Day 32 (the second day of the episode). The clothes Rob and Jenna wear in the RC are shown drying behind them (suggesting it's afterwards, since Rob's shirt looks wet when he's in the canoe). The reward appears to involve a getaway with a loved one, to what looks like a similar site to the coffee bar, except at night. So the Rob-Jenna argument, which either occurs the day after the RC, or later in the same day as the RC, could well take place while the RC winner is away from camp. Butch and Heidi are watching what's going on, but there is no sign of Christy or Matthew. Or, this could simply be after everyone gets back.
