The actor also discusses that season 4 finale fight, which left him ‘heartbroken.’

I personally was heartbroken, he tells EW.

It’s really soul-crushing.

Very, very soul-crushing.

for Jack as this family saga edges closer to completion?

But I think the creation of who he became and first fell in love with is to be explored.

This Is Us - Season 3

We saw some of that in season 3 with Vietnam.

To that end, Ventimiglia is rooting for more to explore with those other Pearson brothers.

So hopefully Angarano can come back and we can dance a little bit more.

This Is Usis not only entering the backstretch of its run, but its returning at a tumultuous time.

(Creator Dan Fogelman recently confirmed that the show will tackle these issues.)

It’s on the minds of the writers," he says.

Responsibly, that is.

Corona wasn’t around when Jack was alive.

It’s going to be a challenge, but I think we’re up for it…

I know that I’m not going to put that in jeopardy or risk.

You have to check that you’re there for your crew…

I think we’re all going to be very grateful for that and not squander it.

Speaking of that ending… Youre not going to get that out of me, Ventimiglia warns playfully.

And every time the creator lets slip another sliver of that ending, it’s rewarding to Ventimiglia.

You start to really see this magic that’s coming in the future.

And it’s a lot of hope.

It’s a very hopeful thing to experience as an artist.
