"More than one, I imagine." McGonagall rose to her feet and pulled her shoulders back, revealing her still impressive stature. She looked down at Hermione and gave an apologetic smile. "Watching Dumbledore, I always imagined my duties were confined to drinking tea and paging through ancient books. Apparently I was wrong." As the Headmistress moved past, she put a hand on Hermione’s shoulder. "Stay as long as you like, Miss Granger. Or take your leave before I’m back. I know there’s a certain wayward Gryffindor waiting for you at home." She winked, then followed Madame Pomfrey out the door in a sweep of sage-green robes.
