Meanwhile, Hal, one of Robert's former students, searches through the late professor's old notebooks. He hopes to find one last piece of hidden genius. Soon, Hal discovers a notebook containing an important mathematical equation. Shockingly, Catherine claims she wrote the complex work herself. However, neither Hal nor Claire believes her.
