Nurse Hammer watches in amazement during the Mercy Heights Hospital talent show when Hiro creates an illusion of Emma disappearing. She then takes Hiro back to his room and forces him to stay in his hospital bed, as he was not supposed to be up. Emma supports Nurse Hammer's judgment on this.
Nurse Hammer responds to the influx of patients after a New York train crash. When she assumes that the hospital employees don't know what "seriously injured" means, she offers to give them a hands-on example.
"You understand the meaning of 'seriously injured'? 'Cause I can happen to give you a hands-on example."
