“This is Us” has quickly become one of the most buzzed about new shows this fall. The series, which premiered on NBC on Sept. 20, drew audiences of more than eight million and kept them by revealing a shocking twist that connects the main characters.

Creator Dan Fogelman assures fans that there are more twists and turns to come this season, though that was not what he and the show’s writers set out to do. In fact, he told Entertainment Tonight that doing so would “be impossible.” While there will be continued revelations during Season 1, fans tuning in shouldn’t expect another “gigantic twist” for some time. Fogelman said that the biggest surprises to viewers will likely be how the relationships of those revealed to be connected in episode 1 panned out over the years.

“It is very hard. We’re not doing a big, gigantic twist every week; the best way I’ve been able to describe it is if somebody took all your home videos of your life and your childhood, particularly, and your family and mixed them in a bag, things would surprise you: Who is still in the videos five years later, who’s not in the videos, where relationships are years later versus where they are in the beginning,” Fogelman said. “The show will continue to challenge the audience and subvert their expectations a little bit and there will be surprising choices made.”

The show will air its second episode on Tuesday, titled “The Big Three.” According to a synopsis on NBC’s website, the show will dive deeper into each of the characters introduced in the “This is Us” premiere. Kate (Chrissy Metz) will take her health and weight loss journey into her own hands. New boyfriend Toby (Chris Sullivan) sticks close by her side, showing her the importance of letting go of her fears of being scrutinized and having fun. Meanwhile Randall (Sterling K. Brown) is trying to reconnect with his long lost father, but wife Beth (Susan Kelechi Watson) has questions about William’s (Ron Cephas Jones) intentions. Kevin (Justin Hartley) is facing new beginnings of his own after he’s left reeling from quitting his job on the set of “The Man-ny.” Fortunately, he has the help of his agent, Lanie (Katey Sagal). The episode will look back on Rebecca (Mandy Moore) and Jack’s (Milo Ventimiglia) early years as parents as well, showing the struggles they faced in their marriage.

During episode 1 viewers were introduced to the “This is Us” cast as well as a major curve ball. After revealing a bit of background on each character it was revealed that they’re each connected in a very special way — they’re family. Kate and Kevin are two-thirds of a set of triplets. The third child died during delivery. Randall is their adopted brother and Rebecca and Jack are their parents. The show jumps through time, showing the characters in both the past and present.

“This is Us” airs Tuesdays at 10 p.m. EDT on NBC.
