Dr. Rox, it sounds as if there's been a detour and a roadblock on the first day, and so, the TBC makes better sense. Phil hasn't given out clues, except for a TBC in-leg mat situation, and that is the only thing that makes any sense.
Meanwhile there's that item just re-posted in this thread that the observer said was a team from two seasons ago -- as TAR 17 is currently being aired there, is it possible that was a reference to Jet-Cord; is it possible the source didn't see them reach Phil? I'm not saying they aren't last, just that they made it without the source seeing them.
