Alice recognizes that the monologue Lydia is rehearsing is about love. This would further imply that Alice is able to feel love despite losing so many of her other mental faculties—otherwise she would not have recognized the emotion. Alice once told Lydia to remember, in case Alice herself couldn’t, that she loves her. Her ability to identify love sends the message to Lydia that, even though she no longer recognizes her, Alice still feels that love for her.
