Izzie has gone absolutely crazy. I could see Cristina acting so irrationally with Burke because they actually have a legitimate relationship, but she has no reason to put everything at risk to save this guy.
I love how Richard sent Cristina to run Trauma 2 and kept Burke in Trauma 1 to avoid her finding out about him. It’s amazing he can keep such a level head in these types of situations.
People at this hospital fall in love way too fast. Derek with Meredith. Meredith with Derek. George with Meredith. Callie with George. Alex with Izzie. Izzie with Denny. Burke with Cristina. Cristina with Burke. I mean SERIOUSLY!!
