Warning: spoilers ahead for Episode 14 of Supergirl Season 3, called "Schott Through the Heart."
Supergirl went in a darker direction than usual with "Schott Through the Heart." The episode (which finally brought the show back to the airwaves after a long hiatus) showcased Winn Schott, revealed the death of his villainous father, and introduced his mother, Mary. Laurie Metcalf of Roseanne and Lady Bird brought Mary to life on Supergirl, and she joined Jeremy Jordan to craft a fascinating dynamic between mother and son. Jeremy Jordan spoke with CinemaBlend about his big episode, and he said this about whether Laurie Metcalf could return to share the screen with him once more:
According to Jeremy Jordan, we can't expect to see Winn and his mom interacting again in what remains of Season 3. Laurie Metcalf scored an Academy Award (and Golden Globe) nomination for her role in Lady Bird, and she is now working on a play. She didn't have the time to hang around the Supergirl set after she wrapped! The good news is that Laurie Metcalf evidently fit right in with the cast of Supergirl and Jeremy Jordan would be glad to have her back.
"Schott Through the Heart" did end with Winn and Mary on good terms and belting their way through a karaoke number. Given what we know of Jeremy Jordan's vocal chops thanks to the Supergirl/Flash musical crossover, we can bet that singing with Winn could only endear Mary to him more. What can't be made better by a duet version of "Take On Me" in a bar? Supergirl will evidently continue to mention Mary, so it's not like she'll drop totally off of Winn's radar again, which is good news for the poor guy. He doesn't deserve to lose his mom all over again.
Jeremy Jordan also spoke about how he and Laurie Metcalf worked to create their dysfunctional family dynamic for the episode, saying this:
The complex family dynamic in "Schott Through the Heart" was the product of Jeremy Jordan working with the writers to develop his character even further beyond his usual role as comic relief, and Laurie Metcalf evidently fit the bill for what they were looking for in Winn's mom. Hopefully we can count on Metcalf reprising her role in Season 4 or beyond. Supergirl did score a renewal for another season, so we'll have to cross our fingers that the timing lines up for more of Winn and Mary together on screen.
