Christine Palmer is a Marvel Comics character that will appear in Doctor Strange, played by Rachel McAdams. Alongside Claire Temple, Christine Palmer is one of the Night Nurses. As such, she has dedicated her life to using her vast medical skills and knowledge of medicine to heal superheroes.
Not much is known about her personality, but since she's not a Netflix character, we can infer that she's more peaceful, kinder and less aggressive than Claire Temple.
Christine Palmer was created by Stan Lee and Al Hartley.
