Doesn't make sense (spoiler)
Watching this series again for the umpteenth time, and tonight I'm up to Season 5 Episode 6.
The previous 'griftees' plan was to take the profit from the convincer and go, rather than then invest more as the hustlers expected. The guy planning it said he wanted to get back the half million he had previously lost, plus a million. The other three people, he said, could split the rest.
But if the plan was to walk away with just the £1m bait, how would that work?
I think I need to get a life quite soon.
