Jennifer Morrison is joining "This Is Us" season four in a recurring guest star role. Morrison starred as Emma Swan on ABC's "Once Upon a Time" until 2018, voices Catwoman in an upcoming animated Batman movie, and recently directed an upcoming episode of HBO's "Euphoria."
TVLine was first to report the news of her casting, adding that she will have a "substantial" presence on the show.
Speculation is she'll be the mysterious mother of Kevin's (Justin Hartley) future child, who we saw very briefly during the flash forward at the end of season three.
When we last caught up with the cast, they couldn't tell us much about what's to come. But it does sound like we're in for a tough parenting ride with Kate (Chrissy Metz) and Toby (Chris Sullivan), and we'll get some backstory about how Jack (Milo Ventimiglia) and Rebecca came to be, as well as how Rebecca got to be with Miguel (Jon Huertas).
Creator Dan Fogelman had previously told EW that season four is all about "restarts," as everybody in the family embarks on new journeys, and it may be a "very scary period" for most of the characters.
"This Is Us" returns Tuesday, September 24 on NBC.
