Well, she was already over Jason's time. But I bet she might have been bitching at Production.
Actually, I wonder if one of the mirrors became loose through repeated use, and couldn't stay level to reach the next target. Obviously, they should have bought 20 mirrors, not 4, and switched them out for each round. Or at least tightened them between the rounds.
Jason, going first, may have had an unfair advantage. Of course, it's Jason, so BB won't do anything to mess him up.
