Sympathy for the Devil

I'll try not to spoiler it too much so it will be a little vague in places.

The story of our death row inmate continues and he discovers he's a match for the dying boy. But will Sheppherd allow him to die?

Meredeth meets Derek's mother and Mark 'fess's up to his affair with Lexie. Alex and Izzie get a little closer and Izzie has to face some home truths about her relationship with Denny. (If she doesn't want him can I put in a bid?)

Mark has some words of advice for Callie and I think George has one line, possibly. And Christine gets closer to Hunt?

Actually, for all my terse summing up, this is a terrific episode. I feel some conclusions to some story arcs approaching and the beginnings of others. As an episode, a solid 7.5 out of 10.
