Mandy Moore recommends This Is Us fans buckle up for the show’s final two episodes this season.
“These episodes are stressful,” she tells ET. “They’re emotional, as every episode is, but I think there will be some bit of resolution, and then a little bit open-ended for the actual finale.”
Tuesday night’s episode will be a celebration of Randall’s biological father, William, who died in last week’s episode. Then, Moore says next week’s season finale will be another Jack and Rebecca standalone episode.

“The episode really follows Jack and Rebecca before they're Jack and Rebecca,” she teases. “And then that sort of counterpoint to that is, sort of where we've left them in 1996.”
The couple’s ‘90s-set story is rocky, with Rebecca about to go off on tour with her band, leaving Jack behind to watch the children. Rebecca wanting to tour set Jack off into a bit of a tailspin; he returned to drinking after years of living sober.
“So, there's some cracks in the foundation of their relationship,” she continues. “It's interesting to see the juxtaposition between who they were before they met, and who they are at this kind of really pivotal moment in their relationship.”

The season finale of This Is Us airs on NBC on March 14 at 9 p.m. ET. After that, fans will have to wait until the fall for new episodes -- and Moore totally gets how brutal that wait will be.
“I'm bummed, too!” she admits. “I miss reading these scripts. I miss being with everybody already, and we've only been off for three weeks. I would encourage people to just watch the season again.”
In the meantime, you can get your Mandy Moore fix on Disney Channel. ET caught up with the actress at the Beverly Hills premiere of her new animated show for the network, Tangled: The Series, a sequel to the 2010 movie. It premieres on March 24. A special TV movie, Tangled Before Ever After, kicks off the new story on March 10.
