“SHOCKING! After years of secrecy, Will Estes (Blue Bloods) publicly revealed his girlfriend for the first time: Who is her identity?

Now another noteworthy actor is stopping by Boston Blue. According to TVLineDoctor Strange in the Multiverse of Madness star Xochitl Gomez has been cast in a recurring role, with her first episode airing Friday, November 21.

Gomez’s character is a “quick-witted” and “charming” woman named Penny who has a “mysterious past” and whose storyline intertwines with none other than Sean.

Boston Blue episode 6 will also see the return of Ramirez as Baez. While Danny and Lena look into a home invader, Sean ends up in a “budding romance” with “unexpected complications.” While not confirmed, it appears that Gomez’s character Penny will be romantically linked with Sean.

Boston Blue stars Wahlberg, Sonequa Martin-Green, Ernie Hudson, Maggie Lawson, Gloria Reuben, Marcus Scribner and Mika Amonsen.

The character of Sean was originally played by Andrew Terraciano on Blue Bloods, but the role was recast for Boston Blue.

Gomez’s star power skyrocketed after playing America Chavez in Doctor Strange in the Multiverse of Madness.

Gomez has also appeared in Raven’s HomeYou’re the Worst and The Baby-Sitters Club, and will voice a character in the upcoming animated film The Cat in the Hat, which is in theaters on November 6, 2026.

Now she will play a major role on Boston Blue starting this month. It’s unknown at this time how many episodes she’ll appear in during the police procedural’s inaugural season. Fans will have to tune in to find out the revelations about her character’s mysterious past and how her connection with Sean develops across the season.
