Rosemary enters Wonderland following her brutal murder by Bon back in 1974. Bon coaxes her into this realm under the twisted guise of "fixing" her or making her beautiful, promising she will be reunited with her missing husband, Jack, and her lost children, Edd and Molly. Instead, her consciousness is subjected to a terrifying transformation process.

The Wonderland Forms within this realm, Rosemary's appearance shifts drastically depending on her state of consciousness:The Living Spirit ("The Sheep"): When Rosemary initially arrives in Wonderland while transitioning between life and death, she takes on a stylized, doll-like form known officially as "The Sheep". This avatar is a black, sheep-like entity with a pale grey face, wide doll-like eyes, and streaks of black tears running down her cheeks.
