Not a lot is known about Ryan’s role in “The Thing Under The Bed,” although viewers can reasonably assume she plays the wronged wife at the story’s center. Ryan’s character is likely to be named Mary, considering the cast list includes Mileiah Vega as “Young Mary” and the promotional materials imply her character has a traumatic past. Only time will tell whether Mary can uncover whatever dark secrets her community has tried to cover up in the years since her childhood.

Despite how much the star’s work leans toward the comedic, Hiller has also had roles inEvil,The Watcher, andFBI: Most Wanted. Since 2022, he has starred alongside Bridget Everett in the dramedySomebody Somewhere. That series sees Hiller play the heroine’s colleague and friend, but his role inAmerican Horror Storiesis likely to take him down a darker path.
Supporting Cast and Characters
Mileiah Vega, Phoenix Carnevale, and Erin Beirnard Round Out The Cast
Alongside Hiller and Ryan, “The Thing Under The Bed” includes a sparse supporting cast, judging byIMDB’s listing for the episode. This could be indicative of the episode’s storyline, as it might mean Ryan’s character spends some of the story alone or with only Hiller’s character for company. Mileiah Vega plays “Young Mary,” Phoenix Carnevale plays a Reporter, and Erin Beirnard plays a Nurse. These character names alone don’t give away much, although the presence of a nurse and a reporter suggests a hospital stay and an event that earns media attention within the episode’s story.
Mary’s younger self may end up hospitalized after an attack by the eponymous monster, only for her to go back to this traumatic event as an adult after the death of her husband. Ryan’s character might have been blamed for a death in her childhood that was really the thing under the bed’s doing, and this cycle might occur again with her husband and force her to confront her past as a result. If this is the case, Hiller’sAmerican Horror Storiescharacter could be an authority figure, like a police officer or doctor, who doubts her version of events.
