In the season finale, Addison and Sam finally get together while Charlotte and Cooper get engaged much to Sheldon's dismay. Pete and Violet work over their issues, while Dell and Maya get involved in a car accident and the severity of Dell's condition is overlooked while Maya was being attended to in the operating room. Dr. Amelia Shepherd, younger sister of Derek Shepherd (Addison's ex-husband), operated on him but was unable to resuscitate following Dell's heart failure. Maya survived her operation to save her spinal cord and prevent paralysis while at the same time she gives birth to a girl, who also survives the ordeal.
