Ari took stormed off, back to the castle after her and Snape's equal duel, there she caused much chaos, things hadn't gone far enough until she found Mrs. Norris... Ari looked at Mrs. Norris; she found herself a perfect opportunity to get back on Filch for the amount of times he'd caught her out of bed, walking about the corridors at night and being in forbidden parts of the castle. She drew her wand, "Larcarnum Inflamarae." she muttered and the tip of Mrs. Norris' tail caught fire. She skipped away as though this was nothing and stuck a few firecrackers into a suit of armour nearby. She walked away as though nothing had happened as the suit of armour exploded with fireworks exploding in many different directions.

Mrs. Norris's eyes widened, almost popped out of her head, as she leapt in the air, a moment of silence when suddenly, "BREEEEEEEEOOOOOOOOWWWWWWW!" the cat screamed louder than she ever had and bolted down the corridor.

Filch was in the dungeon sweeping the floor when he looked up, in the direction of the door to where the cat's cry had come from, "Mrs. Norris...?" he heard another shrill scream and hobbled as quickly as he could out the door. "My sweet!" he cried.

He ran towards her when he saw the jet of orange flee down the corridor, leaving a trail of thin smoke behind her. Argus quickly grabbed a bucket from one of the classrooms, filled it with water and hobbled after the flaming cat as fast as he could, chasing her with the bucket of water. He threw water everywhere in attempt to try hit her with it to extinguish the flame. The water finally hit her, her tail made sort of a sizzling sound as the flame went out; the corridor was a complete mess, with water everywhere.

Ari ran from the scene in hysterical, evil laughter as she heard all this going on; she couldn't help herself; her acts were legendary afterall.

Mrs. Norris leapt in the air, "RRRRR-EEEEE-OOOOOWWWWW-GRRRRR-EEEOOOWWW!" She screamed, landed on her feet and hissed at Filch, completely sopping wet. Her eyes narrowed and she bolted off down the corridor, veered off around a corner and disappeared.

Cassandra-Rose, who happened to be walking about the halls, heard the commotion, upon seeing the water on the floor and Mrs. Norris on the run, she looked at Filch, "FILCH! What on Earth are you doing? CLEAN IT UP!"

Argus didn't want to anger Cassandra as well as Mrs. Norris; if only he'd realized the mess he caused before she pointed it out. He stopped and looked down the corridor, at the water on the floor. His eyes popped out of his head and he quickly hobbled off to fetch a mop. When he returned, he quickly mopped what he could up, but his eyes quickly fell towards him as he saw Mrs. Norris fly past the end of the corridor, "my cat's tail was on fire... MRS. NORRIS!" he yelled and ran down the corridor, the mop trailing behind him. He was, indeed, in Mrs. Norris' opinion, chasing her with a mop.

Mrs. Norris knew no different when she saw her master run towards her, carrying a mop. 'I need DRYING! Not mopping!' she thought to herself in alarm, 'HE'S MAD! THE BLITHERING IDIOT HAS GONE MAD!' she looked down the corridor and saw he was catching up to her, she let out a might screech, "REEEEEEOOOOOOOOWWWWW!" and darted off.

Argus flailed the mop in the air in rage and despair, "BUT MY SWEET!" he threw the mop behind him and hobbled after her, both hands outstretched before him.

"FILCH! YOU BLITHERING IDIOT! IF YOU DON'T CLEAN THIS UP! YOUR CAT IS NOT GOING TO BE THE ONLY THING ON FIRE!" Cassandra yelled after him.

'HE'S GOING TO STRANGLE ME!' Mrs. Norris yelled in her mind but all Filch heard was another loud, "!" she looked behind her and saw him gaining on her, 'HELP! HE'S TRYING TO KILL ME! MAD! HE'S GONE MAD!' again, the only thing Filch heard of this was, "BREEEEEEAAAAAARRRRR!"

"Mrs. Norris! Please come back!" Filch begged as he continued hobbling after her, his hands remained outstretched; not just to her, but many others who saw the sight, would agree Filch looked like a half-dead zombie, with his water-splattered filthy shirt and messed up hair, not to mention his bulging insane eyes and his menacing facial expressions.

Mrs. Norris stopped dead at the end of the corridor, her eyes widened at the sight of him. Fear ran through her, she pushed her ears back and raised a paw threateningly. Her braver disappeared when she saw Filch hobbling closer. "REEEEEEEEEOOOOOOOOWWWW!" she screamed and ran off, 'HE'S NOT HUMAN! Someone!' she yelled in her mind, "REEEEEEOOOOOWWWWWW-OWWWW... BREEEEOOOOWWW!" she screamed loudly and darted under his legs, running towards the other end of the corridor, 'HE STINKS TOO!'

Filch tripped and fell on his arse as Mrs. Norris flew through his legs. He stood to his feet, shaking, "THAT. HURT!" he spat. His eyes bugged out of his head, he looked more insane than he had when he was hobbling after Mrs. Norris zombie-style. He was deeply scared of losing her, which would explain some more of his quivering, however anger was a big part of it, at whoever set her tail alight and caused this mess in the first place. He started after Mrs. Norris again, tripped on some water; he realized he'd done a complete circle, chasing Mrs. Norris. He scrambled to his feet and hobbled back over to the mop as quickly as he could.

Mrs. Norris watched on, terror in her eyes as she saw the sight, 'HE'S DRUNK! HIS LEGS ARE ROTTING... HE'S GOT THE MOP AGAIN!' she pushed her ears back as far as they could go, her sopping wet tail, though thinned out from the water, still obviously fluffed up; her sopping fur, though thinned out, still obviously stood on end. Her droopy face would have reminded anyone of angry Professor Snape in cat form.
