It's one thing using a ladder in celeb versions (as long as the celeb doesn't act like they've won when they shouldn't have. Yes, we're looking right at you, Vogue) but I don't think they should use them in the regular show. What if she had 'won'? She'd have gone through when someone more able than her didn't. They should just set a time limit after the winner has finished and if she couldn't do it in the time, just end the event.
