This scene confirms the fact that Lauren is in even greater danger in the outside world than Harry or Zahra are because of her hyperempathy. At the same time, Lauren defies Keith’s prediction that she would be weakened by her hyperempathy to the point of not being able to survive. In actual fact, Lauren’s condition often makes her behave in an even more fierce and ruthless manner than she otherwise would. She cannot survive around people in mortal pain, and thus has no choice but to kill the man she has injured.
