Sheldon attacks Penny one night after leaving a pub. Howard and Leonard walk past shortly after the attack and see Penny lying at the side of the road. Howard does nothing but Leonard, who is experienced in first aid, attempts to treat Penny but gives up after a few minutes because he is late for a conference. An unknown passerby calls for an ambulance but at the hospital, Dr Amy fails to spot Penny's head injury and assumes she is unconscious because she is drunk. Penny dies from her injuries two hours after admission to the Emergency Department. An inquest later determines that Penny would have survived had she received prompt treatment.
