Millie reflects on Nina’s erratic behavior and the chaotic state of the master bathroom as she cleans, disgusted by recent discoveries like a used tampon on the floor. Wondering about Nina’s mental health, Millie debates whether to look in the medicine cabinet, then gives in to curiosity.

She opens the cabinet and sees numerous prescription bottles, noting one for Nina Winchester labeled haloperidol. Nina’s voice calls from the hallway, forcing Millie to shove the bottle back and compose herself just as Nina enters and questions what Millie is doing.

Nina fixates on Millie’s cleaning methods, criticizing the nonorganic sink cleaner and implying Millie slacks when unsupervised. After observing a demonstration and offering backhanded feedback, Nina leaves, having sown doubt and asserting control.

Alone again, Millie resists petty retaliation and instead looks up haloperidol, learning it is an antipsychotic. The discovery validates her concerns, leaving her ashamed of snooping yet increasingly uneasy and fearful about Nina and the household.
