"Oh boy...that looks like a really bad scrape, l-lets go wash it off"
He nodded
After a little they we're at a shower, he didn't really want to go in with him so he just turned on the shower and opened the door
"Just umm...go ahead and stick your shoulder in there?"
He nodded and stuck his shoulder in
The sand and blood washed away, He genlte scrubbed his shoulder with a rag since he wanted to get all the sand off
He winced, it hurt a bit
"S-Sorry...I just have to get the sand off..."
He tried to smile at him a little, fighting through the pain
"....A-Alright, your g-good!"
He smiled for real, trying to show his thanks
