After a few words of wisdom from Ventress, Younger finds a novel way of raising the village's crime rate, while Bellamy spies an opportunity to get closer to Gina when the pub landlady is injured in an explosion, and Peggy is asked to put on a bet for a dying friend, who subsequently dies before he can collect his winnings.
