Nigel explained to E! Online last night how the finals will fit all that dancing into an hour show:
And as for that upcoming season finale, Nigel spills that it's going to be a little different than usual, thanks to the upcoming holiday. He says, "This is our very first six-person finale, but that's only happening because we're short a week [this season]. Everyone is going to dance with everyone else, but we only have one hour for the performance show, for the 'dance-off,' if you will. So girl A is going to dance with boy A, B and C, and girl B is going to dance with boy A, B and C, and so on. So everybody is going to dance with everybody. Normally in the finale, the boys dance together, and the girls dance together, and they do a group dance as well, but we don't have time to do that."
