Molly Grue is a major character in the story and the film. She isn't beautiful, but she is soft-hearted and cares for others' pain. Tammy Grimes did her voice in the film. Her biggest dream was to see a unicorn, but had lost hope as the years went on, until she meet The Unicorn.
Molly shows exceptional wisdom. She identified Schmendrick as a wizard when first meeting him and even commented on him keeping the unicorn in a cage. She served as the moral compass for Schmendrick and a listening ear for Prince Lir. She is also the common-law wife of Captain Cully.
