Frank demands an elderly passenger give up his seat aboard a crowded vehicle, prompting fellow passengers to warn, "Frank, are you crazy?" and to dismiss him as 'a bit off.' Frank insists he just needs to stretch, takes the seat, and offers to shake hands. Later an onboard scuffle targets the driver; a bystander cries, "That's a foul!" and invokes Rule Two: passengers cannot attack the driver, ordering everyone not to disturb the driver. After the rule calms the scene Frank is thanked and departs, but someone murmurs, "A dual domain?" leaving a new question unresolved.
