Invasion Wiki

Ailsa Chapman is a character featured in the Apple TV+ series, Invasion.


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.[1]

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.[2]
