This Is Us season four is finally here and it's introducing us to a whole new set of characters. The trailer for the new season gave us a quick glimpse of what's to come and the season four premiere connected all the dots. Well, at least a few of the dots.
Not only do we meet Toby and Kate's grownup son Jack (and his wife), but we also meet a potential love interest for Deja. Curious to see how they all connect to the Pearson family. Keep scrolling to learn more about all the new and returning stars for This Is Us season four.
