WARNING: The following contains spoilers about Jack’s death on This Is Us.
Tonight, fans finally found out how their beloved Jack dies.
At the top of the episode, Jack wakes up to find his house is completely ablaze. He manages to get Randall safely into his room with Rebecca, who tells him that Kevin is sleeping at his girlfriend’s house. Jack then runs to grab Kate, as the fire grows bigger.
After safely getting Rebecca, Randall, and Kate downstairs and outside using a bedsheet as a harness, Jack runs back inside, hoping to save Kate’s dog Louie. And just when we think he’s dead and the fire has swallowed him, Jack busts through the front door with the dog in hand. And some family memorabilia. What a guy.
So if he didn’t die in the fire, how’d Jack die?
As Rebecca is making calls home and getting Jack a chocolate bar, we learn that Jack went into cardiac arrest and died.
