  Lockhart did an odd swishing of his wand before it promptly fell out of his grasp and on the floor. He quickly made up some excuse picking the wand up and smiling brightly. Harry didn't pay much attention to that other than shake his head at Lockhart's terrible abilities. He did however notice Snape whisper something into Malfoy's ear, the boys smirk afterwards was enough for Harry to realize something was about to happen.
