Dr. Chapman is the on call neurologist at the hospital when Trevante, Caspar, and Jamila arrive, seeking help. They want her to induce a seizure on Caspar, in hopes of it giving him better in sight on how to stop the invasion. She is initially reluctant, but eventually agrees.
Dr. Chapman runs tests on Caspar, who apparently collapsed just outside the hospital. Unfortunately, she reveals to Trevante and Jamila that Caspar has no brain activity.
