Ian was pretty good. You could see the agonies he was going through when he buzzed in and it was the wrong answer. It really looked as if it meant something to him.
Meanwhile Hannah just stood next to him smiling and doing nothing. Having said that, that's probably better than her buzzing in with a wrong answer when one of the other two might have known it.
She was worth three points, one for being there, one for her one correct answer in the final chase, and I think she helped with one of the pushbacks.
They might have won without her, but then again they might not. But they all get the same amount of money, no matter how much, or how little, they contributed. it's probably the best way to do it.
it would be different if the prize money was divvied up the way they used to do it in "Divided". I never watched that much when it was on, but I've been watching some of the old footage on YouTube.
The trouble with that show, much like Goldenballs, was that it was really only the last five minutes that was interesting. The rest of it was pretty dull.
