Out of Body Experience
Ok this one didn't exactly involve a patient. A donor heart was attached to a machine to keep it pumping and then placed in a box. Cristina was tasked to keep an eye on it until a team showed up to take it away. Needless to say she wasn't that thrilled about the situation until Richard informed her that the heart was the key to everything she wanted. (Earlier, Teddy told Cristina to make a wish list of surgeries she wanted to perform). Cristina channeled the heart-in-a-box mojo and finalized the list she had been agonizing over.
