The needle went in and Sam sucked in a pained breath

"Sorry, Sammy." Dean gently pulled the needle through the torn flesh of Sam's arm, completing the stitch.

Twenty stitches later, Dean tied off the line. "Want a breather before I do the other arm?"

Gray-faced and hollow-eyed, Sam shook his head. "Finish," he said hoarsely.

Dean handed him a bottle of water. "Drink this while I re-thread."

Swaying slightly on the chair, Sam drank.

When the bottle was empty, Dean started to stitch again, keeping an eye out in case his brother decided to take a header.

Fucking ghouls.
