Plot summary
Patrick Jane and the CBI are joined by scientific criminal profiler Dr. Montague ( Linda Park ) to investigate a double murder, which appears to be the work of a serial killer named Caveman. For Jane, it becomes a competition to prove that his methods are superior, and Dr. Montague learns that statistics are not everything, while they discover that the two murder victims did have a connection - they rode the same bus. However, after going on a date with Rigsby, she informs him they have a small chance for a successful relationship because it is clear that he is still in love with someone else. Dr. Montague and Jane strike a friendship and, as a gift, she gives him a profile she put together for Red John.
