She was told by Knowby that he needed assistance with an ancient translation, but was instead tricked into entering the cabin by him with the goal of transferring Henrietta's host demon to her body.
Tanya was dragged underneath the cellar stairs by Henrietta Knowby and mortally wounded while Ash was searching the cellar for Henrietta. Ash, believing her to be dead, escapes the cellar and waits for Henrietta at its entrance. However, the mortally-wounded Tanya emerges instead, only to be immediately dragged back into the cellar and killed for sure.
- Tanya technically made her debut in one of the Shemp's beer commercials promoting Ash vs Evil Dead Season 2.
