Alex just wants to tell the truth even if it hurts the patients. Derek has Bailey as an intern for a day. Cristina is given an advice by Dr. Webber to go back to the basics. With that advice, she was able to find a way to get Burke to kick George out of her apartment. Now she is able to walk around naked. Callie’s secret is out: she lives in the hospital.
