Sakura knelt down in front of him and looked at his foot from where she was, naturally not really noticing anything odd about it; but if it hurt then it hurt. She gently lifted his foot into her lap and did not look at him at all, wanting to keep a professional vibe around her. If this was happening when they were younger and Sakura had all her knowledge of healing, she probably would have taken every chance to help Sasuke in order to impress him with her abilities, but that was not as important to her anymore. What was important was to be serious about all of her healing requests, remembering how Tsunade had taught her to never take any situation lightly, no matter how mundane or "easy" a subject was to fix.
Gathering some chakra into one hand, she held the foot steady with the other and then slowly placed the green aura of light healing-chakra against his ankle. Finally looking up to him, she attempted to begin her distraction, starting off with a very small smile.
