Dr. Frost assigns Carol to be her attending physician while the rest of the interns are working on other injured marathon runners; Carol decides to take it as an opportunity to ... (more)prove to Dr. Jacobs that she is deserving of her respect. Daniel and Lexie discover that Caleb has an irrational fear of feet, preventing him from helping them deal with the massive backlog of patients. They put him through exposure therapy, which allows him to overcome his fear. Carol finds that Dr. Jacobs is stubborn and refuses to take her advice or let her help, which she takes as a sign that Jacobs is unwilling to acknowledge her as a doctor. However, Dr. Jacobs explains that, being a black female physician, she has to hold herself to higher standards in order to be taken seriously. She then tells Carol that she does, in fact, respect her.
