The cast of This Is Us is preparing for a bittersweet goodbye.
They said as much at the premiere of the NBC show's sixth and final season on Tuesday, Dec. 14, with Mandy Moore—who's played both young and old versions of the Pearson family matriarch for the past five years—telling E! News correspondent Francesca Amiker that she's still struggling to accept that this is the beginning of the end.
"I'm savoring every moment as I kind of have from the beginning," Moore said during the exclusive conversation, which aired on E! News Daily Pop today. "I think we all have. It's just been so special. I'm definitely grieving."
"It's joyful," Metz added of the final season, "But it's very bittersweet."
The Pearson siblings' father played by Milo Ventimiglia was a bit more forthcoming about what season six holds.
"Things change," Ventimiglia told E! News. "[But] in true Pearson fashion, you're gonna learn more, discover more, have our hearts broken a little bit, have them mended back together."
Justin Hartley also teased what's to come.
"We're gonna have a lot of people laughing, we're gonna have a lot of people crying," Hartley said. "Hopefully we get an ending—and I think we will—hopefully we get an ending that everyone's happy with."
Does that mean fans will be getting the closure they "deserve," as E! News' Amiker put it?
"Well, define deserve!" Chris Sullivan joked. "You're gonna get the closure you're gonna get. You're gonna get closure which is more than we get a lot of times in life, right?"
