As gifted a doctor as Stephen Strange may be, he still needs some medical help when he's the one who needs to be operated on. The honor goes to Dr. Christine Palmer (Rachel McAdams), a colleague, friend, and former love of Stephen Strange who has clearly put their romance
behind them - refusing to date coworkers due to her "Strange Policy." For those diving into the character's comic book history, the source material may not be a perfect match, because Christine is actually a combination of two different characters.
There is a character in Marvel Comics known as 'Christine Palmer,' but she's the star of her very own solo "Night Nurse" comic book series. Though that version of the superhero-healing nurse has little ties to Doctor Strange, the prior version, 'Linda Carter' (not that Lynda Carter) has plenty. In fact, one famous scene between Linda and Stephen is recreated almost completely in the film, with Christine subbing in for Linda.
