  • The problem with your daughter isn't her bed, it's her brain.
  • (Trying to give Regan a needle) This is to help you!
  • (Referring to Regan) Her condition isn't quite what it seems, Ms. McNeil. Nobody knows what the cause of her hyperkinteic behavior is.
  • Lesion in the temperal lobe. It's a kind of seizure disorder.
  • (In a deleted scene after getting hit in the face) HELP ME! HELP ME!
