On her last day as a medical student, Masters must decide whether to stay on with House's team as an intern or to join Dr. Simpson's surgical team. She initially opts to join the surgical team, but reconsiders House's offer after learning that the last patient she treated under House has taken a turn for the worse. While brainstorming the case alone, Masters believes Kendall has salmonella, and checks her bones for signs of infection. An MRI reveals a potentially fatal lymphoid sarcoma in Kendall's humerus. Masters tries to convince the patient to amputate the arm but Kendall refuses, and her parents refuse to overrule her. Unable to accept the patient's decision, Masters goes to House for advice. House suggests that she break the rules if it is so important to her, but she refuses. After talking once more with the patient, Masters causes Kendall to experience bradycardia and convinces the parents that the cancer has caused a clot to lodge in her heart. By pointing out that had this incident taken place at sea Kendall would be dead, Masters convinces the parents to consent to surgical amputation. After amputating Kendall's arm, Masters resigns her position at the hospital.
