This Is Us has been filled with sad moments this season, but the most gut-wrenching had to be the revelation that Milo Ventimiglia's character Jack is no longer alive in present day. Since the sad news broke, we have been racking our brains trying to figure out how it all goes down, and during a recent episode, we finally got some closure. As Kate takes part in a drum-therapy class at an adult weight-loss camp, she recounts heartbreaking memories from her past, including her father's funeral. While the clip offers that the kids were teenagers, it still doesn't exactly answer how Jack dies. Honestly, I wouldn't be surprised if the show comes full-circle by having him die on their shared birthday. There are a few theories about his cause of death, and we've gathered four of the most intriguing here.
Even though Jack seems to have kicked his alcoholism, it may have still taken a toll on his health. It's possible that all that drinking leads to heart problems or increases his risk of developing cancer. We don't even want to think about that.
2. Heart Attack
Kate is so distraught over Toby's heart surgery, and while obviously any person would be, the storyline might have been backwards foreshadowing that her father also suffered from a heart condition.
3. Plane Crash
Hold onto your seat, because this final theory is a doozy. Some fans seem to think that Jack actually dies during the 9/11 terrorists attacks. Tumblr user just-an-outlaw pointed out that both Kate and Kevin seem to have a fear of flying, and that Kevin threw away his model airplanes after his dad's death — and that's not the only connection. Randall lives in New Jersey and Rebecca seems to live nearby. Perhaps the family moved to city sometime around 2001? While the details certainly make sense, the only problem is that the kids would have been in their early 20s, and the flashback suggests that they are a bit younger when Jack dies.
4. Miguel Kills Him
OK, OK, this one is out there. Miguel probably isn't a murderer, but what if Miguel accidentally kills him? And that's why Kevin doesn't like him; not because Miguel marries Rebecca. Jon Huertas dispelled this theory in an interview with E!, saying, "What kind of show are you watching? This isn't some murder mystery!" But we're still not convinced that he doesn't have something to do with the death.
Alas, it seems like we may not be getting answers right away, as the show's creator, Dan Fogelman, told Entertainment Weekly that the how for Jack's death is going to take much longer to reveal. "By the end of the season, you're going to know a lot of the details of the how and the ramifications of it," he said. "In terms of the detail of how he died, was it illness? Was it something tragic? Was it something else? You're not going to know that for a little bit because we want to show that in the show. So that's going to take a minute." Thankfully, the series has two more seasons to tell Jack and the rest of the Pearson family's story.
