Marie was a student at a girls' school in Flint, Michigan who created a "Supernatural" fan fiction musical.
Unsatisfied with Carver Edlund ending Supernatural with Dean quitting hunting to live with Lisa and Sam mysteriously back from Hell, she decided to create her own "transformative" fan fiction in the form of a play.
Marie took the role of "Sam Winchester" in the play, replacing Maggie. She sung "Carry On My Wayward Son" at the end of the performance.
Later that day, Marie met Carver Edlund, who praised her work, calling it "Not bad".
- Marie revealed to Dean that she is a Sam-girl, believing Sam to be brave and selfless.
