The Best Episodes Written By Kip Koenig

Cristina is bothered by a new year's mandatory work limit. Izzie patient, Denny Duquette, wants two things: 1. a heart transplant, 2. Izzie. Addison detests Derek's trailer, Derek visits Meredith's mom, George treats a young teen hermaphrodite frustrated by her pre-pubescence. Other news includes patients doing uncanny things and relationship havoc being wrecked between the doctors, as per usual.

A traumatic car accident fills the ER. Izzie pushes the boundaries of her probation. Cristina has a crisis of conscience about her deceptive teamwork with Burke.

Derek and Meredith try (unsuccessfully) to be discreet as they spend the night together at Meredith's house, but their haggard appearance speaks volumes to everyone - including Bailey, who warns Meredith to end the relationship. Meanwhile George suspects an anesthesiologist of drinking on the job but is reluctant to speak up about it, Alex treats a former competitor who now finds honor in self-mutilation, Izzie has to deal with a patient who won't let go of his girlfriend - literally, and Cristina seems to be battling a case of the flu.
