American Dad! Season 20 serves as a great reintroduction to the animated series for those fans who might have not have been keeping up with all of the episodes it aired with TBS, and the animated series took this head on with a couple of shake ups to the status quo. Namely bringing Francine’s sister Gwen back to the series after 12 years with a new voice actor behind her, and Steve’s ex-girlfriend Debbie 17 years after her last prominent appearance in an episode.
American Dad Brings Back Francine’s Sister After 12 Years With a Twist

American Dad! Season 20 premiere, “Aw Rats, A Pool Party,” sees Francine addressing meeting up with her sister Gwen for the first time since she went to jail in the Season 10 episode, “Now and Gwen.” It’s revealed that her sister is now eight months pregnant, and bears no ill will towards Francine for getting her put in prison (even if she had vowed revenge during that first appearance). But not only is she visually different, she has a different actress behind her this time around as well.
