S3E18 Aphrodite / Dr. Jekyll and Miss Hyde

In "Aphrodite," Professor Blair jeopardizes both his sanity and life in pursuit of an enchanting woman embodying flawless beauty. Meanwhile, in "Dr. Jekyll and Miss Hyde," Dr. Griffin, a rather plain and unremarkable female psychiatrist, uncovers a startling revelation about her true nature and hidden instincts.
