Here's a Refresher on Everything That Happened at the End of This Is Us Season 1

While the series finale didn't reveal how Jack dies, the revelation that Jack and Rebecca are separating is just as heartbreaking. After getting into a huge fight following Rebecca's show, the two come to the decision that they just need some time apart. Jack packs up his belongings to head over to Miguel's, but not before making one last grand gesture by telling his wife all the things he loves about her. "You're not just my great love story, Rebecca," he says. "You are my big break, and our love story — I know it may not feel like it right now, but baby, I promise it's just getting started."
