Mary was revising over her charms book with Remus in the courtyard when Mulciber and a few of his friends run past. Mulciber snags the book from her hands and tosses it to the side with a smirk before running into the castle. She closes her eyes for a moment to calm down before reopening them after hearing students talking among themselves, saying things like, "Is that smoke?" and "What do you think is on fire?"
Remus was staring in the direction that everyone else was pointing. "Mary… I think that's the Green Houses…"
Mary looks up at him then toward the direction he was looking. She automatically knew the direction and takes off toward the smoke; leaving Remus is the courtyard to pick up her charms book. The screechsnaps screamed so loudly that she could barely hear them, Fang however could hear them clearly and his barking could be heard from Hagrid's hut across the grounds.
By the time Mary finally reached the Green Houses she was outraged. The flame had already engulfed two of the houses and was starting consuming another. Professor Sprout and her current class were trying to keep the fire at bay without much luck. After yelling at a few of the students who were just watching (she scared them into helping), Mary also took out her wand and casted Aquamenti at the fire. When the fire was out, Mary walked past everyone - or rather they moved out of the way with fear that they would get stabbed - and into the burnt houses to inspect the damage.
The Green House that the fire was started included the Venomous Tentacula and the Self-Fertilizing Shrubs. It was also the Green House in which she kept her baseball equipment. It was all ash. She bends down and picks up a handful of the ash, letting it fall through her fingers as she fumes to the point that she was shaking with anger. She was way too pissed to even think about crying about it. She hears a quiet screaming in the second green house and walks over to find a screechsnap trying to find something to make it happy. She quickly runs to an untouched Green House and grabs a small pot and fills it with fertilizer. Returning to the surviving plant she gently picks it up and places it into the pot after cleaning it of ash. Mary returns to the untouched Green House and waters the Snap until it calms down. Walking back outside, she hands the plant to Sprout and leaves without a word. She storms past Remus and into the castle until she finds Mulciber in the Great Hall.
"HOW COULD YOU!?" she screams, "YOU UNCULTURED PURE BLOOD, SUPREMACY SWINE OF AN APE?!"
Mulciber simply smirks which made Mary even more pissed that she was almost turning red.
"Is the little psychotic bitch, having an episode?" He muses. "Should I go get your blood traitor boyfriend?" he sneers, "How about your mudblood of a friend?"
She jumps at him, screaming. "YOU ARE GOING TO REPLACE EVERYTHING THAT WAS BURNT!"
Mulciber falls backwards onto the ground, just trying to avoid getting punched. Mary feels a few hands pull her off of the Slytherin, but she doesn't notice who as she struggles and tries to escape from their grasp. "LET ME GO! HE BURNT DOWN THE GREEN HOUSES! HE DESERVES TO BE STABBED WITH A FORK AGAIN!"
"Mary!" Someone shook her and Mary blinks a few times before she focuses on who was in front of her, Lily. It was then that Mary actually looked around. Students circled them, the younger ones trying to strain their neck to see what was going happening. McGonagall, Sprout, and Dumbledore were on the other end of the room, letting Lily calm her friend down. Remus and Charlotte were the ones holding Mary back. Mulciber was laughing as he stays pinned to the ground by Sirius and James – who both wanted to beat him black and blue but resisted as they only cared about Mary's safety at that point as well as the fact that there were Professors around and they didn't want to risk him getting away with it this time. "Don't let him have the satisfaction. Sprout and McGonagall have witnesses see him leaving the Green Houses right before they caught fire. He won't go unpunished this time."
Mary jerks free, turns around, and walks out of the Great Hall. Ignoring all the eyes on her and blocking out Mulciber's laugh. She had to clear her head and she couldn't tend to the Green Houses or even transfigure a baseball to look like Mulciber's head and swing at it until it fell apart, so she walks straight directly to the hidden room (the same hidden room that started her close friendship with Sirius the previous year and that she loved to be in if not in the Green Houses) to let out her anger. Once inside the room she yells in frustration and throws a vase at the wall. The vase shattered on impact so she threw another. She smirks as each broke and scattered on the floor around her - more vases, little toys, and even a few books. She threw anything that would break or give her a satisfying thump. Mary then picks up a ball and starts to throw it against the wall, but stops mid swing and looks at it. She sinks to her knees, letting the baseball roll from her hands and across the mess around her. She felt empty as she stares at her hands resting on the ground in front of her, every inch of her body shaking. Even though she knew everything was replaceable she couldn't help but feel like she had lost a huge part of her life. She could owl her parents to get a new bat and a few baseballs. Sprout could order more Tentacula and Shrubs. They would never be the same Tentacula and Shrubs that she took care of since seedlings. The new bat will not feel the same to her or will hit the balls the same way as the one she had almost worn out during games with her dad at home. Mulciber's laugh echoes through her head and unable to hold it in any longer she pulls her knees to her chest, put her head in her arms, and cried.
