Since This is Us premiered in 2016, America has been obsessed with the show. From the drama, to the touching moments between family members, to the mysteries that have been teased since the first episodes, audiences are hooked.
But being a This is Us fan is a rough experience. There are laughs and smiles, but also tears and a lot of anxiety for your favorite characters. One of the major issues still giving us grief is how Jack will die.
Fans have come up with all sorts of theories to explain why Milo Ventimiglia's character passes away between the flashback and present day segments.
Kate's fear of flying and the fact that Kevin throws out his toy planes make a plane crash one of the most likely explanations.
Fans originally speculated Jack would die in the 9/11 attacks, but the show's timeline makes the 1994 USAir jet crash more likely. He could also die in a fictional plane crash.
But some fans have come up with truly bizarre theories to explain Jack's absence. Ventimiglia joked that his "favorite" theory involved Jack being murdered by Miguel, so he could marry Rebecca.
In a new interview, the actor shared some details about Jack's death, and warned fans to prepare themselves for a big surprise.
While everyone else is in the dark, Ventimiglia was told about Jack's true fate when he joined This is Us. That means he gets a kick out of all the speculation and fan theories we come up with.
While the actor promises the truth is coming "very, very, very, very soon," he also warns that fans may not like it.
"I imagine that this one is going to hurt," he told US Weekly. "It's definitely going to hurt. In the short amount of time, people have really grown to love Jack. And Jack and Rebecca and the family and the kids, the adult big 3."
"And I think this is just one of those moments where you know it's on its way. And it's going to sting. It's going to hurt. But I think ultimately, hopefully, people can accept and hold the memory of Jack with a full heart and move that into their lives."
And despite all our guesses, Ventimiglia says nobody has theorized the actual cause of Jack's death. In fact, he thinks no one will see it coming.
"I think people have seen what's contributed to his death, possibly. But no, no one's guessed it yet."
He even played coy when asked if Jack's history of substance abuse will play a part. "Maybe," he said. "Sure. Maybe not. Sure."
As Ventimiglia says, "I just keep telling everyone "˜just wait.'"
