Do you sense the beginning of a horror story? We do: a woman moves into the house; the house is spooky; the woman has serious misgivings; etc. We also learn in this stage that the narrator’s husband makes all the decisions for her, telling her when she is sick and what she is suffering from. This is part of the initial situation as it highlights a certain path that the story may follow.
The narrator tries to express her own opinion to her husband, but is overruled on every count. This is conflict, yes, but note its one-sided nature: John doesn’t take his wife seriously. In other words, this conflict results in the narrator’s repression.
Forced to lie in bed all day and rest, the narrator becomes completely entranced by the wallpaper and is drawn into trying to decode its design. This adds a layer of complication to the story as the narrator’s vibrant mind deals with repression by focusing on her surroundings.
This is the ultimate moment of rebellion for the protagonist as she takes action towards freedom. She is finally upsetting the status quo and declaring her own sense of agency. This all adds up to one heck of a climactic moment.
All of this upsetting of the status quo comes with a certain amount of backlash. When John comes home to find the door to his bedroom locked, he begins freaking out. The uncertainty of the narrator’s fate leads us to conclude that this is the moment of suspense.
The narrator’s actions are so extraordinary and so shocking that her husband faints. This is the denouement because it answers our questions about how John will react to his wife’s craziness. Rather than bullying her or trying to talk to her, he simply faints.
This is the conclusion of the story because it’s how we leave the scene of the story. It functions a bit oddly as a conclusion, however, because it doesn’t exactly wrap up loose ends. For instance, we’re wondering if the narrator ever gets her sanity back. Does her husband regain consciousness? Does she get tired of creeping? Wait a minute. This doesn’t seem like a conclusion at all!
