When Peter and Chris interrupt Stewie’s TV time, the angry baby goes back in time to break up Peter and Lois so he’s never conceived, but is shocked when he is reborn into a “Downton Abbey”-esque British household.

When the family fails to help Lois with the Christmas shopping, she walks out on the family and the Griffins must try to save Christmas on their own.

Brian becomes romantically interested in someone and it inspires him to use Stewie's time machine. Strange consequences result from their journey.

In an effort to improve his writing, Brian convinces Stewie to go back in time and bring Mark Twain to the present day, but the plan goes awry when Twain overindulges in pornography.
