In the book, Joanna says she and Walter bought their house from a couple called Pilgrim, who lived there for two months before moving to Canada. And the existence of a town full of robotic wives
would not be very far out of the scope of Scott Pilgrim.
Joanna in the original is still alive.
During the infamous supermarket scene, it seemed as she was walking toward the camera that she was starting to look nervous after her initial Stepford Smiling. This troper believes that she destroyed the robot and is now posing as it in order to avoid getting killed like the other wives.
- Wouldn't the men, especially Walter, know the difference? The robot double was more buxom than Joanna
- Or another theory, that the robots have the orginal brains and eyes (explaining the significant close-up on the robotic Joanna's eyes) from the actual wives, and that one some level they still have their real thoughts and emotions, they just cannot act on them due to programming, explaining why Joanna began to look upset and nervous.
