There was a season where one team had won a Fast Forward with another team during an Intersection period, and then won an individual Fast Forward on a subsequent leg. (Oswald and Danny, season 11, legs 8 (Poland, during an intersection) and leg 10 (Hong Kong.)
I'm surprised this wasn't mentioned (or I didn't see it in this leg.)
In any event, the show has never had an intersection with an odd number of teams; it would put a solo team at an advantage or disadvantage, depending on the circumstances.
I'd be surprised if there's a second FF this soon if there is to be a second one this season.
As to the helicopter, er may not know why the helicopter shot is in the promos, but it did occur to me that teams might have had to ride in a helicopter before or after the helicopter task. Haven't they done something like that before? I can visualize it (Argentina or Brazil or Guam or Hawaii in an early season, perhaps?) but I don't have time right now to wade through to look. But I do remember something like that.
I think we probably have at least one active route marker task in here somewhere; and the possibility is that the waiting team member at a roadblock gets a helicopter ride. They've done that sort of thing already. And from the preview for the season, there's a hint of a helicopter ride on the last leg of the Race, IIRC, so I think the use of helicopters is quite deliberate, Peach. Just to throw that additional thought in.
