Narcissa was glad that Hermione was the first to leave, entrusting Mallett with her tranfiguration notes as Severus sent word by his Patronus that there would be a surgery in Granger Hospital this weekend. The process seemed simple enough, once everyone got over the idea of what muggle surgery entailed. Once all of the questions were answered and Fleur agreed to let David keep her wing (who has hopes to replicate it, I daresay) the teaching staff began to follow in her wife's footsteps and made their way back to the castle.
