At this point, This Is Us fans know Milo Ventimiglia's character, Jack Pearson, is dead, but the 39-year-old actor has a message for those eager to find out the details.
Ventimiglia appeared on Jimmy Kimmel Live ahead of the hit NBC show's season finale on Tuesday, and said fans should be focusing on how Jack lived, as opposed to how he died.
"The one thing that you do know is Jack is dead, and everybody's fascinated with knowing how, and when and why," Ventimiglia said. "The thing that I keep thinking about, or keep talking about to people is, worry about how he's living -- why he's living. Those are the moments. You don't want to focus on death. You want to focus on his life."

When Kimmel asked if viewers will get answers to why Jack's dead during the season finale, he teased, "Maybe, maybe not. Maybe you will."
ET spoke with Ventimiglia earlier this month at NBCUniversal press day, when he echoed that he doesn't want fans to focus on seeking out clues to how Jack died.
"I think people need to put away their desire to know and be satisfied with that, and know that it's coming," he explained. "It could be the next episode. It could be the second to last episode. It could be a ways away."
"But I think the idea is [to] embrace the moment that we're in and know that it's coming," he added. "You gotta be ready for it at any given time. It could very well be this season. You never know, you never know.”
