The man in the nightgown lives in the room next to Sasha’s at the hotel in Paris. He’s overly interested in her life and always tries to talk to her in the hall. He even knocks on her door late one night and just stands there smiling at her, but she pushes him away. He’s no longer friendly to her after this encounter, keeping track of her comings and goings and calling her a “dirty cow” in French when René visits her room. But after René tries to rape Sasha and then leaves, the man in the nightgown enters her room—despite her distaste for him, she pulls him to the bed.
