The dumbest thing is I know they won't DQ any of them in the final competition because then it'd look bad on TV, but really now.
I think it's too late for them to call Nat out for it, because then they made her stay up there for like an extra hour for nothing and she'll probably flip, and they'll only warn Kevin even though he's had an advantage all comp(by looking at the gears dead on and just doing whatever they do). But really now.
