Bailey is adamant that Burke and Cristina should be punished, Derek doubts his abilities, Izzie tries to take a stand against Mark's patronizing behavior, and Meredith deals with family in two very different ways.

Patients include Meredith's half-sister in labor that puts a strain on her personal needs in the family department. George's needs in the family department include a couple of brothers who don't respect him. Richard's needs in the family department include his desire to retire, but Preston's tremor and deception puts the ability to satisfy those needs on hold. Izzie needs to face up to Mark or become his personal slave. And Miranda tries to help Derek get back in the surgeon saddle when he questions his ability, thinking he failed Burke.—Moviedude1

Dr. Weber finally confronts the issue of suitable punishment for Burke & Cristina. Burke contemplates how to heal his hand tremors. Over Derek's initial objections, much of the staff participate in a tricky separation of adult conjoined twins, who spend much of their screen time in entertaining bickering. Sloan continues his professional and sexual harassment, but finds Izzy isn't taking much of it. George is angry at everyone in sight, but shows late hints of returning to his former self. His father gets a new heart valve via Dr. Hahn and Cristina. Bailey maintains her own standards while questioning Richard's discipline. Meredith's half-sister, Molly, comes in for an emergency C-section; Addison taps Mere as the liaison to Molly and her mom as Addison operates on the baby. Step-mom offers to be Meredith's extra family, but Mere rejects her, having enough trouble with her house-mates ... not to mention Ellis, who is ranting about Richard returning to his wife. Mere and Ellis finally meet in the present for a moment. Mere also begs the gang to let Cristina "off the hook" for her transgressions, reminding them that they've all fallen far short of ethical standards at one time or another.—norcekri
