Does Susan find her Cardigan?

No, she has to find a different cover

Susan searched the corridor up and down, desperately hoping to find her missing cardigan. She checked inside boxes, behind canvases and on the floor, but her cover was nowhere to be found. “Dangit” she hissed, covering herself with her hands and leaning against the cold wall nearby. “I can’t stay here like this. Gotta find something else.”

A clunk from the end of the corridor alerted Susan. Realising she had to hide, she dashed down the corridor and took shelter in a propstore. She closed the door and crouched down behind it, praying she hadn’t been spotted.

The sound of footsteps passed by the door, and once they’d faded, Susan let out a sigh of relief. “Thank god” she whispered, getting to her feet and looking around. There were various props and stage decorations around her, any of which could act as a modest-enough cover to hide her unintentional nudity.
