After the incident with Cho the school staff had their eyes open for anyone displaying sadistic or sociopathic tendencies. Sadly they couldn't find anyone and even the victim didn't even have memories of any event that would lead them to someone... Well, with the exception of the many, many people she had aggravated directly or indirectly by her scheming. Indeed Professor Flitwick was horrified to additionally find that she was also selling her body to someone for them to complete her assignments for her. This person's name being Roger Davies, he was promptly reprimanded and given a daily does of a potion called "Labido Blocker", to prevent him taking advantage of anyone else. The only thing that prevent further punishments was his status as a Pure-Blood, something that had some of the teachers fuming as he had been having sex with Cho since she was a second year.
But, as it happens, not all teachers are as ethical as some would suggest. This was seen when information about Roger Davies actions towards Cho was released among the students, causing him to become a social outcast and while being branded a Pedophile in the Muggle world was career destroying, in the Magical world it had different implications due to the low birthrates and how much people valued children as a whole.
As such, the next day a Daily Prophet detailing everything that'd happened on the second page had him sobbing into the pages, the same thing was observed the next day when Howlers from almost the entire country was sent to him, causing most of the Hall an ear ache.
This however wasn't the end for Roger Davies troubles as after a couple too many grief fuel'd mid-day butter beers he ended up asking Fleur Delacour out to the Yule Ball in-front of a large portion of the school as they were leaving the Great Hall.
Roger "F-Fleur! Please go out with-Come to the ball with me!" he shouts, correcting himself half way through his sentence.
Fleur scowls at him and crosses her arms, "You? Are you not ze Pedophile I 'ave been 'earing so much about?" she says, imaging someone attempting to do the same to her little sister and almost bursting into angry flames.
Roger "It's all lies! Cho was making it up!" he says loudly and stubbornly.
Fleur looks a him like he's a clown, "I never zaid anyzing about Cho... I zink we are done 'ere Mr Pedo." she says, quickly turning and walking away.
Roger grits his teeth in anger, his life had thoroughly been destroyed by whoever had cast the Imperious on Cho and everything had been going wrong for him. This was his last hope at getting his reputation back, after-all, why would he go for anyone younger if he could land Fleur? Unfortunately his drunken reasoning and eloquence didn't translate into words.
"Don't turn your back on me! You'll be coming with me!" he shouts, knowing full well that he'd bribed a few seniors in Ravenclaw to avoid her, increasing the chance in that she won't have a date.
Fleur herself knew that she needed a date but the person she'd set her eyes on was already competing for someone else, she found herself struggling to contain herself when around his aura and even found herself daydreaming about him on occasion. She's been asked by many, many people to the ball but everytime she considered accepting them she always thought back to "him"... She continues to ponder this while ignoring the shouts from the angry Roger who's quickly approaching her.
Roger grabs her wrist which shocks Fleur as she had never expected him to lay his hands on her, "Unhand me pedophilic swine!" she shouts, starting to lose control of her Veela side.
Roger "No, you'll be coming to the ball with me, and you will like it." he gets in her face, "Do you understand me!"
Fleur "Non! I am going with someone else!"
Roger growls "Who is it! Ah, I bet it's that fucking freak that you've been staring at all lunch!"
Fleur halts, did he just call Reima a freak? Her composure finally breaks as a fireball appears in her hand, she slams it into Roger's face while a large group of students watch. The boy falls to the floor screaming and writhing as the flesh on his face melts and his hair burns away. The surrounding students shout and scream for a medic as Roger's screams echo throughout the castle, eventually leading to Professor Flitwick appearing and almost vomiting at Roger's new visage. It looked as if he'd held his face in fiendfyre fora couple seconds!
Flitwick "Oh my! Who did this! Who is responsible!" he shouts while looking over the victim and trying to heal as much as he can before Pomfrey get's here courtesy of his Paronous message.
Fleur stands proudly with a scowl, "It waz me."
Flitwick "Why, why would you do something like this!?"
Fleur "He attacked me!" she exclaims, rage in being questioned on her actions apparent.
Flitwick is almost intimidated by the furious girl but continues to try and tend to whoever this is... He's currently unable to identify them due to how horribly mutilated his face is.
Eventually Pomfrey and a few other teachers get to the scene, a few gagging at the stench of burnt flesh while others at the sight of Roger's face. She immediately transports him to the infirmary while Madam Maxime takes Fleur away in order to find out what happened. Leaving all the students behind still gossiping on what'd just occurred
