The most hotly debated topic in the world of television right now is Jack Pearson’s death on This Is Us, because no one knows how it happens… fans just know it’s coming.

On Thursday, March 9, star Mandy Moore — who plays Jack’s wife Rebecca on the hit series — pretty much confirmed that we won’t be getting an answer during the Season 1 finale next week.

“I don’t think I’m supposed to [tell],” the brunette beauty admitted while promoting her new Disney Channel show, Tangled: The Series. “I should text the powers at be. My publicist is plugging her ears.”

The actress revealed, “I would just caution people that the show, we’re very lucky, has been picked up for two more seasons and I think you sort of have to weigh the possibility of potentially not finding out this early on in the series.”

Milo Ventimiglia, who plays Jack, previously spoke out about the highly-anticipated scene, admitting “we’re a ways off” from seeing it play out on screen.

“People are truly going to grieve — not mourn — grieve,” the 39-year-old said in an interview with Entertainment Weekly. “It will happen when [series creator] Dan [Fogelman] wants to tell that story… It’s going to happen when it’s supposed to happen, but also it’s got to be a large impact that drives these kids and Rebecca into the second part of their life.”

In the season’s penultimate episode, viewers discovered that Jack’s daughter Kate (Chrissy Metz) blames herself for his passing. “It’s my fault… I’m the reason he’s dead,” she tells her fiancé Toby (Chris Sullivan). We later find out that the father-of-three talked to the teen before getting into his car while still intoxicated. It’s hard not to wonder whether the patriarch ends up dying in a drunk-driving accident.
