Being a cold and gloomy day at Hogwarts, nothing much was happening. All out door classes had been cancelled so most students were sitting indoors, happily playing games, doing homework, and chatting amongst themselves. The teachers were all in their staff lounge just chatting amongst themselves about classes, certain students, and above all just enjoying each other's company with the free day that they were having. Only two teachers were doing any work and they were the Headmistress, Amy Wilkinson and the Potions Master, Professor Severus Snape.

While the whole school was indoors in the warmth of the school buildings, Amy and Severus were out in the grounds, near Hagrid's hut. They were both practising spells and having a major duel against each other. After being out there for about 6 hours so far, Amy and Severus were soaked from the rain and looked like drowned rats. That didn't stop them though. Severus had challenged the Headmistress to a duel after they had an argument about who was better with using their wands. Being very competitive since a young age, they had always challenged each other even when they were students attending Hogwarts.

Thunder struck across the grounds, most of them being real, with the occasional one or two coming from the wands of Amy or Severus. The duel was full on and neither of them would stop for anything.

"Expelliarmus!" Snape screamed. A bright blue charge came from his wand and hit the Headmistress' arm. Her wand went flying out of her hand and through the air until it hit the floor a few metres behind her. She smirked and turned, running towards her wand. Once she had picked it up she looked at him and yelled. "Crucio!" Snape was immediately hit with a red charge and fell to the ground. He could see strong visions of his past, which including him seeing his father fighting Voldemort. After about a minute Snape stood up again and aimed his wand at Amy. "Furnunculus!" He yelled. A bright yellow charge came from his wand and hit Amy causing her to brake out in boils. He laughed. "That's a good look Headmistress." He said sarcastically. She frowned and then before long the boils had gone and she was back to her normal looking self. Snape scolded. "Immobulus!" He said sternly. He knew that this spell would turn Amy into a stiff board if it hit her. She watched it come towards her and just before it hit she yelled. "Impedimenta!" As soon as she said this spell, Severus' spell completely stopped only inches from her. "Damn!" He said stamping his foot. She smiled at him and then placed her wand by her side. Severus wondered what she was doing and soon after he placed his wand also by his side. She knew this was the way to get him and to win the duel. Standing there looking at each other, they both watched closely for any movement of their opponent. Before they had started the duel, they had both put a spell on themselves which would able them to use the killing curse Avada Kedavra on each other. The spell would make the curse powerful enough to knock their opponent out, but wouldn't be enough to kill them. Amy desperately wanted to beat Severus, as they always challenged each other and Severus seemed to always win. As a surprise attack she quickly pulled her wand up and screamed. "AVADA KEDAVRA!" The powerful bright pink charge came from her wand and knocked her backwards onto the cold wet grass. Severus watched in shock as the spell came towards him and before long the spell had over taken him. His eyes rolled back into his head and he blanked out. He was knocked off his feet and straight into the air. Amy watched in horror as Severus' limp body headed straight towards the Whomping Willow.

CRASH!!!!!!!!!

Severus' body hit the Whomping Willow with such a force that it created a loud piercing noise throughout the grounds. The Whomping Willow swung him around and smashed him into the ground a few times. He was certainly out of it and probably had no idea what was going on. After about 5 minutes of being smashed and crushed in the Whomping Willow, he was thrown back into the air and he hit the ground hard, metres away from the tree. When Amy saw him hit the ground she gasped and ran towards him. His body was limp and bleeding from many cuts and scrapes which had come from the curse, the tree and hitting the ground. She bent down beside him and held his limp body. Trying not to hurt him she lifted him up using a spell which made him hover and carried him up to the castle's hospital wing. "You will be ok Severus. I promise." She said softly.
