I haven't watched this episode yet. Do you mean that this was the person in seat 4, with the others all having been eliminated? If so, I don't blame the Beast for letting him/ her through to be the sole one in the final chase.
The Chaser's questions always seem easier than the contestants'. Yesterday's episode, final question for the chaser: What is 20 trebled? Please! Proper questions.
I could well see his tactics, since he had won so little, go for the big one, with not a cat in hells chance of winning it, forcing the return of full team, with the best player trying to win a £1,000 for each of them.
I am getting more and more convinced that if there was a quiz show with such a number of ways that it can be fixed, it is this one.
The show would be more believable (I think the Chasers occasionally give wrong answers, esp Paul Sinha) if they were only paid their fee if they won - then we would know they were really trying. As it is, they get paid whatever happens
