When Stewie and Brian use the time machine to help Chris learn about history, the three accidentally get stuck in the past.
Brian gets a job writing for a teen magazine. After trailing Meg around for research, he discovers that she has a secret boyfriend who's in jail. When Brian attempts to inform the family of Meg's secret life, it is revealed that her boyfriend has broken out of jail, and has been hiding in the Griffin's house.
Lois returns to name Stewie as the person who tried to kill her. On the look out for Stewie, Joe leads a manhunt around Quahog. Stewie does whatever he can to become the supreme ruler of the world and Lois realises what she must do to stop him.
When Mayor West marries Lois's sister, Carol, they move into the Griffin's house to be one big `happy' family. To make room for everyone, Stewie is bumped out of his room and takes over Chris' room but not everyone is annoyed by the change. Peter and Mayor West bond and become best friends.
After Peter uses Meg's money to buy himself a tank, she gets a job at the new superstore in town. However, the store puts all the shops in town out of business and sucks up the city's power supply. Elsewhere, Brian and Stewie team up to save the town from the corporate giant.
