Harry then demonstrated the charm. Out of his wand came a ghostly white stag. I remember seeing it in third year, but it still amazed me. The safe aura it gave near it was noticeable. What I did not expect was to see my ability to show the purple outlines around the Patronus. They didn’t go farther than that, but I was not expecting to see them around this spell. While I was focused on the Patronus, Harry had everyone separate around the room to give them enough space.
