Even though K/G are in last place right now, I don't think we have anything to worry about. My guess is that they'll catch up to (and pass) T/I with relative ease. The previews showed Gerard talking to WhinyFlo on a train, so either Whiny/BigHair fall back big-time, K/G catch up big-time, or there's yet another equalizer. I don't think Whiny/BigHair will fall all the way from first to last (although, if there's an equalizer, who knows what will happen), so I think T/I will be the next team eliminated. After that, I think it'll be Whiny/BigHair's time to go (), leaving a Final 3 of JV/J, K/G, and the Wonder Twins. Since the JV/J team is the only one left that hasn't used the FF yet, I think they're in very good shape for the rest of the game, and they should make the Final 2. As for the Wonder Twins and K/G, you would think that the WT's would beat out K/G based on their physical conditioning. But, as we've seen a number of times already, K/G are very good at thinking on their feet and on the fly, and I think this could very well give them an edge over the WT's (Plus, we've seen the WT's crack under the pressure a couple of times already; we have yet to see that from K/G). That leaves the Final 2 (in this scenario, anyway) as JV/J and K/G. Now, personally, I'd be happy with either of those teams winning (--though I'd prefer that K/G win definitely!), and I think the eventual winner could very well be decided at the last minute (kinda like last year). JV/J certainly have the physical edge over K/G, but how important will that be in the end (see comments above about K/G thinking on their feet)? I'm gonna go with my gut and say that it won't be as big a deal as it could be.
So, how will they finish? At this point, I'm thinking it will be:
5th - Teri/Ian
4th - Flo/Zach
3rd - Derek/Drew
2nd - John Vito/Jill
1st - Ken/Gerard
Of course, depending on whether or not there are equalizers, this scenario could very well be blown out the window...
