Linda finds out about her addiction.
Linda’s story is departure from the usual flow of many MC stories because in most of such stories, the control is not consciously registered by the victim - or the victim just could not help him/herself. In Linda’s case, her agency is imperfectly preserved and hence there is internal conflict. To better represent that conflict as part of the story, there's need to show Linda's thoughts - this is different from the original text where most of Linda's conflicts are only mentioned in narration. Some license is necessary here.
