Ruby Redux

S11, E19: Eighty-five-year-old Jules "Ruby" Rubadoux (recurring guest star Academy Award winner Red Buttons - "Sayonara," "The Poseidon Adventure") is wheeled into the emergency room and erroneously accuses Carter of killing Ruby's wife 10 years ago. Although Abby believes Ruby is too old to undergo surgery to correct a heart murmur, the attending doctors opt to perform the operation. Meanwhile, Pratt treats a domestic violence victim and makes a date with the social worker assigned to the case. As Pratt arrives for the date, he realizes he has gotten himself into more than he bargained for. Former series star Paul McCrane directed the episode.
