Arguably still the most-buzzed show on network TV, This Is Us returns for season three, and the writers are ready to start pushing narrative boundaries. Said co-showrunner Isaac Aptaker at the TCA this year: A typical episode of This Is Us has three sibling storylines and then a past episode, and every now and then we’ll devote one solely to one character, but this season we’re really throwing everything out the window and saying all bets are off. So maybe we’ll do an episode where every act is a different time. Maybe we’ll have something that jumps five timelines in an episode. We’re really pushing the limits of what people will comprehend. As for specifics, we know that we’ll get to see a lot more of Jack’s backstory (In many ways, Jack may be the character we still have the most to learn about, said creator Dan Fogelman in a previous interview), including his time in Vietnam with his brother (guest star Michael Angarano). We’ll also see Jack and Rebecca’s pre-marriage courtship, and learn how Rebecca found love again with Miguel decades after Jack’s death. PREMIERE: Tuesday, September 25th
