[BEING REWRITTEN] to heal a wound

"When you begin to notice a wound, that's when it begins to heal. If a patient can feel pain, you'll understand that it means they're on the path to recovery."
"So this pain..." Naruto absently grabbed at his chest. "Will go?"
"Maybe." Tsunade shrugged. "Maybe it'll leave an aching scar. It's impossible to save everyone, but I can teach you how to try. Today, I'm going to teach you Iryo Ninjutsu. I'm going to teach you how-"
The corners of her mouth quirked up, but it looked more grim than anything else.
"-To heal a wound."
 
-"I believe that Tsunade-hime had fixed a wound that no Bijuu or Med-Nin ever could."-

(Or, Tsunade is forced back into Konoha and told to take an apprentice after a... let's call it a 'meeting' with the Elders. Hyuuga Hinata, Haruno Sakura, Yamanaka Ino... those are the suitable candidates. But Tsunade won't go for 'suitable', she's going for a challenge- someone who will be exceptional. She absolutely does not know how her presence and her words would affect the Konoha Rookie 9.)
