 Often there's a role reversal, with Sarah and Geoff engaging in behavior they scold their children for during trances, and Kate and Simon being forced to act like mature adults.Eventually, the children convince their parents by showing them filmed footage, and discover the trigger is any word with "ming" in it, just like the hypnotist's name.They finally track down Ming and convince him to unhypnotize the Spiller parents, apparently restoring them to normal.
