Milo Ventimiglia teases that viewers will be seeing 'different versions' of Jack Pearson as 'This Is Us' comes to an end

• Milo Ventimiglia said "This Is Us" was "so front-heavy with Jack."
• "Now, we've really invested in the stories of the kids and Rebecca," he told Variety.

"This Is Us" star Milo Ventimiglia told Variety that we'll be seeing "different versions" of Jack Pearson as the family drama comes to an end.

"I think toward the end, we're going to see all the sides of Jack. I think we're going to understand who he was to his kids, understand who he was to his wife," Ventimiglia said, in response to whether viewers will see Jack as an old man again like they did at Kate (Chrissy Metz) and Toby's (Chris Sullivan) wedding on the season two finale "The Wedding."

Ventimiglia said that as "This Is Us" nears its ending, Jack's story isn't necessarily one that needs to be tied up.

"The show was so front-heavy with Jack. Now, we've really invested in the stories of the kids and Rebecca. I think that's where it's ultimately leading, those loops closing," he told Variety. "We already know Jack. He'll be there, he'll be around."

The former "Gilmore Girls" star assured fans that "different versions" of Jack "will be popping up" on season six. The exact meaning of his words is unclear, but he appears to be teasing something coming up for Jack in the future, perhaps in a way we've never seen before.

The adult versions of Jack's kids have previously seen visions of their late dad in hallucinations and daydreams, so it's possible that Jack and the memory of him are used toward the end of the story when we least expect it. But Ventimiglia is only speaking about the end of the beloved series in very broad terms.

"We're seeing storylines wrap up and characters journey on," Ventimiglia said. "You will have seen the whole experience of the Pearson clan."

He noted that he feels "good" about the conclusion of the series.

Ventimiglia previously spoke on "The Tonight Show With Jimmy Fallon" about why his on-screen marriage to Mandy Moore might feel so real to fans. He said the pair "almost took vows" with one another at the very beginning of the series.

Some of the promises the costars made, according to Ventimiglia, included: "I promise to always communicate. I promise to not be happy until you're happy. I will always look out for you."

"And we have stayed very true to what we said in the beginning," he added.

The final season of "This Is Us" airs Tuesdays at 9 p.m. ET on NBC.
