Heart beating at its full pace, João had just stopped and turned around to see if the plant had really moved when he was hit from the behind quite forcefully. He shrieked this time, and fell on his back with whatever hit him under his body. In the meantime, with that fear and confusion, his wand had fallen from the wrist holster into his hand and shooted some spell in some direction he couldn't even control. Whatever done was done. Rolling quickly to get up, face all flushed red, he directed the wand at the thing that caught so much commotion. The Ravenclaw girl had beaten him to it though and she was already getting... oh. It was a little boy. João lowered his wand quickly not to be misunderstood as if he had intended to shoot him. Well, he had, and he would have, but for the professor right there who demanded to know what was going on. He, himself, didn't know it exactly either, to be honest. All he knew was, that plant did move, and this boy hit him.

Although, that girl had got him up almost caringly. She also knew his name. To make it worse, the boy was a Slytherin. Why hitting another Slytherin, in front of a PROFESSOR, who was sure to deduct points for disturbing the class?! His confusion turned into anger. Putting more distance between himself and the plant and that over-excited ram-like boy; he said, in an attempt to beat them to answering Professor Bentley: "She--she made fun of my obvious reservation about this plant and he hit me on purpose from behind. So my wand shooted blindly." A quick, effective summary. See? He was COMPLETELY innocent!
