He experiments some more and describes some of the successes to her but as he questions how she is feeling, Georgiana begins to suspect that Aylmer has been experimenting on her the entire time without her knowledge and consent. One day, she follows him into his laboratory, and on seeing her there, Aylmer accuses her of not trusting him and says that having her birthmark in the room will foil his efforts. She professes complete trust in him but demands that he inform her of his experiments. He agrees and reveals that his current experiment is his last attempt to remove the birthmark, and Georgiana vows to take the potion, regardless of any danger it poses to her.
