Please be kind to me; I don't know the rules of Poker. Brady's cards: three sevens and a king, and he throws in the duce to win. A voice says, "Four dueces!" How is that four deuces? The dealer did not say, "Dueces wild." and even if Dueces were wild, is that hand not four sevens?
The other cards we saw (sevens and king) were Sir Colin's cards, not Brady's. Sir Colin had drawn another king, to give him three sevens and two kings - a full house. Brady was already holding three deuces.
It was the dramatic moment of throwing the deuce down in the middle of the table for all to see that we were getting in that shot.
Of course, we all knew it was going to happen - the good guy always wins in the last scene - but it was still fun.
