Happy Birthday to you too, OnyxMoonBeam. I didn't know you are a Leo too!
"Tired...Sam..."
"I know, Dean. Let me finish this and then you can sleep. Can you put some pressure on here?"
"Owhh..."
"I'm sorry, it won't stop bleeding. Let me turn you...maybe I can elevate your arm..."
"No. Owhhh! Don't, S...Sam. It really hurts."
"I think you've popped your shoulder out as well. Don't put your weight on it. Okay?"
"Can't...too sore..."
"Lean towards me, I need to see if it came right through."
"Oh...Sam...Dizzy..."
"Sorry. Okay, lay back. It's not come right through. I'm gonna need to pull it out. Are you ready?"
"Be gentle with me, Sammy."
"Bite me!"
Hope it fits the bill, never done all dialogue before!
