'This Is Us' creator talks 'very heavy' Season 2, show’s 'big challenge'

"This Is Us" fans shouldn't stop stockpiling boxes of tissues anytime soon.

Dan Fogelman, who created the NBC drama series, told TheWrap that viewers should brace themselves for plenty of tough moments in Season 2, given the looming mystery of Jack's (Milo Ventimiglia) death.

"It's very heavy," Fogelman said about the new season. "Our big challenge is also keeping it fun. Obviously, there's a potential death at the center of the season, which naturally makes things sad."

He continued: "I think part of the thing people are talking about [with] the emotion of the show, it's not always sad emotion. It's an uplifting emotion — it's a cry that makes you smile. We want to make sure the show also remains fun and funny."

"This Is Us," which is produced by 20th Century Fox Television, centers on Jack and Rebecca (Mandy Moore) raising their three kids. Fans who have been anxiously waiting for the show to reveal the cause of the beloved patriarch's untimely demise will likely be relieved to know that this will happen next season.

"This Is Us" returns to NBC with Season 2 in the fall.
