2x19 What Have I Done to deserve This?
No one knows what transpired between George and Meredith but George and Meredith -- and they aren't talking, but everyone knows something happened. They suffer in silence over their transgression -- until everything bubbles to the surface, and once the secret is spilled, it's only a matter of minutes before George spills, too -- down a stairwell, where he dislocated his shoulder and then meets a fan of his. Addison suffers for her transgression, too, in the form of poison oak on her va-jay-jay.
