NBC's new drama "This Is Us" got fans crying and gave them chills right in the first episode. That's a pretty good start!

The story follows a group of people all turning 36. The premiere introduced pregnant Rebecca (Mandy Moore) and husband Jack (Milo Ventimiglia) as they were about to welcome triplets; we also met dissatisfied actor Kevin (Justin Hartley) and his dissatisfied twin sister Kate (Chrissy Metz); and then there's Randall (Sterling K. Brown), who was searching for his biological father after being abandoned as a baby.

However, the premiere ended with a major twist tying the storylines together.

*SPOILER ALERT*

Turns out, Rebecca and Jack's storyline was taking place in 1980, 36 years before the others, because they are the parents of twins Kate and Kevin, and they adopted baby Randall after their third baby died. Mind = blown.

The Hollywood Reporter asked creator Dan Fogelman where the show goes after such a big reveal. His answer reveals where next week's episode picks up:

"The structure of the show is very similar in the coming weeks in that it's interconnected stories. We have four main stories as our main storylines. We'll be cutting back and forth between those the same way that we do in the pilot. They start commenting on each other because of the way the series progresses and all the stuff that happens in the pilot. So Mandy and Milo's story is the story of a young couple raising a family, but that storyline will jump around in time. It won't just be the couple taking the babies home from the hospital, it's going to be the story of marriage and family. The pilot may have ended with them having the babies, but the second episode starts in 1988 and you see them eight years after having those kids. Then the third episode will go right back to the day they brought the babies home from the hospital."

Fogelman told TVLine that, as Season 1 moves forward, scenes will be set in 1980, 2016 and times in between. "We kind of refer to it as 'a dramedy version of 'Lost,''" Fogelman said. "You're going to get a real feeling of the evolution of a marriage [with Rebecca and Jack]. You might even meet them in the present day as older versions of themselves."

Sterling K. Brown, who just won an Emmy for "The People v O.J. Simpson," plays Randall, and told TV Guide it's not just age and time keeping the family apart, and Randall is pretty separate from his siblings for a better reason than just protecting the premiere's big twist. "Over time, everybody comes together in a really lovely way," he said. "You understand why, not just as a plot device, they may not be as close in the beginning. Hopefully they get a chance to grow closer over the course of the show."

"This Is Us" airs Tuesdays at 10 p.m. on NBC.
