Cycle (Part 1)

Nathan was trying to figure out what was going on here. This wasn’t how the magic taxi was supposed to work; he had read the journal. He was supposed to say “Have a nice day,” swap bodies with the passenger leaving, and then the passenger (now in the cabbie’s body) is supposed to drive off to continue the cycle. However, instead of driving off, the woman he swapped with got out of the cab and ran away with the cabbie’s body. Nathan had no idea what to do. He couldn’t just leave the magic taxi here for someone to steal. The magic should force her to come back, shouldn’t it? She had to continue the cycle, didn’t she?
