It took a few minutes, but with a patient hand, Snape healed every single cut of abrasion on the bottom and side of her foot before sitting back to look it over. Satisfied, he stood and held out a hand to help her stand. She stood with both feet planted firmly on the ground and looked up to see Snape was relieved. After he used his wand to clean up the bathroom and fix the tiles, he gave her a light nudge on the back to precede him out of the bathroom and inclined his head just a little before turning to head down the hall and downstairs.
