Grace Gardner’s character was written out after the first season of “Scream Queens.” She did not return for the second season, and her absence was not thoroughly explained within the show.
In the first season of “Scream Queens,” Grace Gardner, played by Skyler Samuels, is a central character. She enrolls at Wallace University and joins the Kappa Kappa Tau sorority, which becomes the target of a series of murders by a killer known as the Red Devil. Grace, being one of the main protagonists, works to uncover the identity of the killer while dealing with the various challenges and mysteries of her sorority and college life.
However, by the end of the season, the mystery surrounding the Red Devil is largely resolved. When the show returned for its second season, it shifted focus to a hospital setting with a new mystery and largely a new cast, though some characters from the first season returned. Grace’s character was notably absent, and the show did not provide a significant in-universe explanation for her disappearance.
Skyler Samuels, the actress who portrayed Grace, moved on to other projects, and the creators of “Scream Queens” decided to take the story in a different direction without her character. The lack of closure for Grace’s storyline left some fans with questions, but the show continued with its new setting and plot without revisiting her character’s fate in any substantial way.
