Shake Your Groove Thing

Meredith realizes that she must take on a lot more responsibility when she is told that her mother needs to sign over all of her assets to her. As Izzie prepares to have a party for her boyfriend Hank (the scale of which is unknown to Meredith), Meredith participates in her first heart surgery.
