  Hermione was nose deep in a book about Herbology, she was adamant on getting a higher grade then him this year, and Ron was shining his wand. Hermione was the one who learned about proper wand care, not even Ron who was a Pureblood learned about proper wand care but then again considering the family he came from it wasn't surprising. Percy had already come to them with his nose stuck in the air as he looked at Ron as if he was inferior. He said something about how they were boarding the train and Ron could follow after.  Harry was about to punch the Perfect when Hermione stopped him, he was still about to break the no magic rule and send a Tripping Hex when the boy had left.
