i look at professor slughorn and shake my head. i do a backards sumersault and dodge the stupefy spell. then using my broke arm , as though it was fine, i did a one hand sumersault to dodge the fire coming at me. i go behind the tree where slughorn was and yelled langlock .
i yell " Confundo!" thus hoping that slughorn would be cunfused. then i silently climb a tree far away from slughorn hoping that he didnt see me climbing
