Draco came to the party fashionably late. Instead of the polyjuice, he took his own potion. He was pretty proud of it. Draco could turn into anyone he wanted by just looking at himself in the mirror and imagining how their face and body should look. It was helpful because he didn’t have to look exactly like the other person, but as much alike as he wished. Additionally, he didn’t have to use any of the other person’s body particles and, frankly, his potion tasted much better.
