The stars of This Is Us have been dropping hints about what鈥檚 in store for the upcoming third season, and the latest update from Mandy Moore has us counting the days until its fall 2018 return.

鈥淚 think it鈥檚 our most ambitious [season], but I think we鈥檝e earned it after 36 episodes,鈥 Moore recently told E! News. 鈥淧eople know who these characters are, they trust us, and I think it allows us the freedom to expand the universe a little bit.鈥

That鈥檚 a little vague, but Moore, who plays Pearson matriarch Rebecca on the hit NBC drama, assured fans that it鈥檚 going to be 鈥渢he best season yet.鈥

Moore鈥檚 tease is the latest in a series of updates that have shined some light on the undoubtedly emotional upcoming season: Moore also recently said it鈥檚 not for the 鈥渇aint of heart,鈥 and Justin Hartley, who plays Kevin Pearson, said that some of the storylines would be 鈥渟uper heartbreaking鈥 and 鈥渟hocking.鈥

So far, it sounds like those story lines primarily revolve around Jack Pearson. While season 2 dealt with the soul-crushing death of Jack (Milo Ventimiglia), he鈥檒l be far from absent in season 3 as the show looks back at the early days of his relationship with Rebecca and his time in Vietnam. 鈥淭here is still so much story to mine in this world of This Is Us,Ventimiglia said back in February, assuring fans that the story of his death did not mean the end of his time on the show. He added on Twitter that the character is 鈥測ou. He鈥檚 me. He鈥檚 Us.鈥

This Is Us season 3 premieres on Tuesday, September 25, at 9 pm ET/PT on NBC.
