This Is Us - Season 1The "This Is Us" Season 2 premiere is going to cause emotional upheaval, which, frankly, we should expect by now.

When the NBC drama kicks off its second season, things will get "very heavy," according to creator Dan Fogelman. He opened up about it to EW, and indicated that Rebecca (Mandy Moore), Jack (Milo Ventimiglia), and family will be dealing with the aftermath of the couple's blow-out fight and decision to separate.

"They've said stuff they've never said," he told the publication. "They've said stuff in the heat of the moment that clearly, they felt for a while. I think it takes a while to buy it back. The first episode is all about the ramifications of those things that have been said, and the regret."

The possible silver lining here is that Fogelman's comment on "buy[ing] it back" may hint that they'll recover from their big fight. Yet, even if that's the case, don't know when we'll get happier times, because he describes Rebecca and Jack's storyline at the end of the episode as "very intense."

"The end packs just a huge, romantic, sad, beautiful, melancholy wallop," he said.

We're honestly not sure if that is a good or a bad thing. Whatever the case, the show has a lot more to cover, as well, what with their children living adult lives in the show's other timeline. The pace will move rapidly, and we'll apparently see a lot happen.

"We've only got 40 minutes and we've got eight characters you want to catch up to, so it flies -- in a good way," Fogelman said.

We're ready for it -- well, as ready as we can be.

"This Is Us" Season 2 premieres Tuesday, Sept. 26 at 9 p.m. ET/PT on NBC.
