John Corbett is returning for And Just Like That… season 3, suggesting Carrie and Aidan have ended their five-year break, as Aidan now lives in Virginia. It’s not likely that he happened to run into Carrie, although that happened memorably throughout Sex and the City. Aidan and Carrie could be meeting for several reasons, but whatever it is, it breaks what they agreed upon in the And Just Like That season 2 finale. The couple agreed on a five-year break after buying an apartment together, holding off on their relationship until Aidan’s youngest son graduated.
