Okay a newbie here, so be nice please...LOL
My take on this week...the blind u-turn, is simply a u-turn and the "blind" part is you don't know who u-turned you. I think since C/J, M/M, and L/J are ahead of the others, one of them uses the u-turn on another. C/J uses it on M/M. Mel & Mike and Amanda & Kris simply switch tasks because their piles keep falling. Since we have no further evidence of Amanda & Kris, I think they are the ones to be eliminated.
But then again Lakisha & Jen aren't shown in any of the promos doing the detour yet, maybe CBS is holding out on us, so it could be them that are u-turned and eliminated.
Any thoughts, comments?
