'This Is Us' drops a huge clue about Jack's death and fans on Twitter are devastated

Warning: Spoilers for the second season of This Is Us ahead.

The perpetual sadness machine that is This Is Us has finally built up to the moment its been teasing since early on in the first season: The death of Jack Pearson.

And folks, it's not looking good.

All signs have pointed to the fact that everyone's favorite dad Jack died while his kids, a.k.a. The Big Three, were in their late teens, and a few more recent episodes alluded to the fact that he may have died in a house fire. Well, on Tuesday night, this seemed to be solidified given the fact that the episode left us on a cliffhanger where half of the house is on fire thanks to a faulty crockpot. And now we're all steeling ourselves to weep uncontrollably after the Super Bowl on Feb. 4.

The actor who plays Jack himself, Milo Ventimiglia, told Entertainment Weekly that his character's death is not something that will play out lightly.

"It’s just an absolute soul-crushing event," he said. "I think the best thing I can say — or the worst thing I can say — is: It’s going to be f—ing painful."

Great. Just great.

Golden Globe winner Sterling K. Brown, who plays Randall, asked viewers if they were doing OK after the latest episode (hint: nobody is OK).
