The answer to the question: Whose wife thinks he's a doctor? is inside the article: Paige Collins and her husband Leo come out of a movie theater. On their way home, at a stop sign, Paige unbuckles her seatbelt to lean over and kiss Leo. At that very moment, a truck rams their car from behind and Paige crashes through the windshield. Both of them are rushed to the emergency room, and as Leo, in a voice-over talks about how "moments of impact help in finding who we are" the movie cuts to how Paige and Leo first met. The scenes of how they courted, became engaged and married at the Art Institute of Chicago and share a kiss under the Cloud Gate are interwoven with the present. When Paige regains consciousness, she thinks Leo is her doctor, having lost all memories of the past few years. When her wealthy parents, Bill and Rita Thornton, learn about this, they visit her. This is the first time that Leo meets them, and they do not appreciate Leo taking their daughter, and not being informed. Paige does not understand why he would not have met her parents, after having been married to her. She finds it even stranger that he did not know why either. Nor did she understand why she left law school, broke her engagement with her previous fiance, Jeremy, and why she has not been in touch with her family and friends. Her parents insist on taking her home with them and Paige agrees, thinking she might have married Leo for some mutual benefit. She seeks evidence of the marriage. Just as she is about to leave, Leo comes running to play her a voice message in which she sounds very happy and romantic. Paige decides to go back with Leo, hoping it will help her regain her lost memory. Paige is welcomed home with a surprise party by her friends, but as she is not able to remember any of them, she finds it overwhelming and is extremely confused., can you guess it ?
The answer to this question is:
Leo
