"My name is Poitr, what's yours?" Finding something to say makes him feel better. He barely expects any response; the child looks to be in shock. 

"An ambulance is on the way. Can you tell me anything else about your location? A cross-street or business?"

Poitr describes what he can see from the alley, not wanting to leave the girl. The operator relays this to the ambulance.

"How did she get hurt? Are there any threats still there?"

"I don't know, but there's no one else here."

"Do you have any first aid training?"

"A long time ago. No."

"Is she alert? Breathing?"

"Yes. I'm not sure how alert, she hasn't said anything."

"But she is conscious?"

"Yes."

"Okay. Don't move her. Ask her some questions - where she is, what day it is, what her name is, how old she is, If she's alright with receiving first aid, then get back to me."

He thinks that she can hear the operator, so he turns to the girl and returns to his earlier question.

"Hey. What's your name?"
