January 8 1989

A thick blanket of snow covered Hogwarts school and all it's grounds. The cold winds that accompanied the most recent fall of snowflakes did not stop the students from bundling up and going out to play in the vast white like children half their age. It was time for the students to return from their Christmas holidays and the grounds were ripe with snowball fights. Teachers had been sent out to supervise the students, it was certainly needed when snowballs mixed with magic.

Three sixth year girls strolled along the edge of the black lake, giggling happily as they shared tales of their activities during the break. They had their black and yellow striped scarves drawn tight around their faces and necks, matching thick black robes also helping to keep them warm. Hufflepuffs. One girl stood out from the other two, despite their identical outfits. Nymphadora, don't call me Nymphadora, Tonks. With her vivid, bubblegum pink hair. she was the loudest out of the three but also the clumsiest, probably the clumsiest girl in the entire year. She had already tripped several times over rocks of varying sizes and even over her own feet, she had a shockingly colourful vocabulary. To avoid too many of these accidents, her best friends would often walk either side of her when they were outside, ever since she broke her wrist in second year. Amelia Brown and Rachel Sherlock, the three had been best friends since their first day of first year and that showed no signs of changing.

The trio stopped as two seventh year boys walked past them. One winked at Amelia, the other at Rachel which sent the girls in a squealing frenzy as soon as the boys had moved on. Tonks grinned as she stepped back so they could talk. He loved seeing his friends so excited, even if it was over a boy just winking at them. Not one of them ever got jealous either so that helped strengthen their friendship. Her eyes widened with shock and horror when she realised that there was no ground beneath her feet, She was falling into the lake! Letting out an ear piercing scream, she scrambled to find something to grip onto as she sunk into the murky depths but to no avail. She merely ended up hitting her head and knocking herself out on the way down. Amelia and Rachel lunged forwards as they desperately tried to grasp onto their friend before she completely vanished beneath the surface of the ice cold lake but they were too late, she was gone from sight.

"Get a teacher!" Amelia cried as she knelt at the edge, reluctant to dip her bare hand into the freezing water, even to try and save her best friend. Rachel nodded and sped off, adrenaline fueling her sudden burst of speed. It also helped that she was the fastest runner in the year. She had absolutely no idea where the nearest teacher was, perhaps she would get lucky. Sure enough, within a short while, she collided with the back of the youngest teacher currently on staff. Severus Snape. Rachel let out a small grunt as her entire body crashed into him, sending the tall Potions Master stumbling forwards a few steps.

"What the hell do you think you're doing?" Severus snarled angrily once he had turned to face the panting girl, shooting her a cold glare which had become his signature. He had a reputation cruel and hateful to students and adults alike, especially if the students weren't in his own house. Slytherin. A small frown appeared on his face when he noticed how panicked she looked. "What is it?" His voice was now softer. He knew fear when he saw it.

Rachel struggled to catch her breath, desperately trying to get a lungful of air so she could tell him what had happened. "Tonks.." She gasped, "Fell into.. The lake." She managed, turning and taking off again before she had even finished speaking. Severus' eyes widened with shock and he immediately ran after the girl at full speed. by the time Rachel had returned to the point where Tonks had fallen in Severus had caught up and was right on her heels. His coal black eyes scanned the water in the hope that he would see her but to no avail. He wasted no time in stripping his thick black cloak and matching scarf, also stripping his black overcoat which left him in just a white shirt. The discarded items would just weigh him down once he was underwater. All thoughts of using his wand left him as primal instinct to save the girl kicked in. Taking a deep breath, he dove in.

The water was absolutely freezing and the shock of it enveloping his entire body forced most of the air out of his lungs. He tried to open his eyes but it took several attempts due to the stinging of the cold. Once he had managed to keep his eyes open, he used his hands to push against the water and spin himself around a full 360 degrees to search for her. Second after terrifying secong beat past until he finally spotted her several feet beneath him. She was floating amongst some plants that seemed to be gripping onto her ankles and holding her in a watery prison. It scared him to see that her skin was blue and she wasn't moving of her own accord. Was he too late? He turned his body and started swimming down towards her, drawing level within a few more seconds. Despite the cold water all around them, she felt like ice when he cupped her cheeks with both hands. He needed to get air into her so, knowing the rules didn't apply in this situation, parted her lips and covered her mouth with his.

It took a moment before the air that Severus had so desperately tried to circulate around her body had the desired effect. She started to come around, her eyes opening now. She pulled away from the figure who had given her the air she needed to survive, not knowing what was going on. The coldness of the icy water stung her at first, but she soon familiarised herself with the biting coldness, forcing her eyes to stay open. She didn't know if her unconsciousness had forced her to imagine things. Severus Snape, saving her? It was part of his duties she thought. She gave no more thought. She needed to work fast. She started to quickly pull at the plants that held her captive in the nurky water, wanting to ensure she never surfaced again. Time was running out. It truly was a race against time, and Tonks wasn't one for losing. She was considerably weaker than before when she had first attempted to free herself, but she still pulled with everything she had, needing to free herself soon.

Severus pulled back once he felt her moving, relief flooding through his body. The relief was short lived as he realised that they were both rapidly losing precious air and she was still very much stuck. He gripped her shoulders to try and get her to concentrate on him and not her underwater captors. She immediately stopped her fruitless tugging and looked to his face. He made a besture to tell her he was going down before he forced himself lower down into the depths of the lake. He was now level with her ankles and the plant that gripped her tight. Taking a firm grip with both hands, he tugged sharply and the thin leafy string snapped. One down, one to go. Filled with a new hope, he quickly released her other foot and pushed her up. It took a moment but Tonks soon realised that she was free and used what litte energy she had left to swim to the surface, Severus following close behind.

The moment Tonks broke through the once calm surface of the lake, she was gasping for air. She took in huge lungfuls of oxygen which seemed to sting as she did so, but she tried to ignore it. She couldn't feel anything. The coldness of the water had numbed her body. Severus surfaced nearly a metre away, taking in a big gasp of air in an attempt to stop the pain in his lungs. The cold air burned his throat as he breathed it in casing him to cough at the feeling. Each breath that he took felt like his lungs were being stabbed. Tonks coughed up all the water she had swallowed as Severus located her and wrapped his arm around her middle. It burned her throat as it made it's way up, but it seemed to go unnoticed by her.

Her whole body ached and she had no energy to help Severus as he slowly dragged her to the shore. He could feel his energy ebbing away with every small movement he made. He doubted he would even be able to make it to land. Each time his head bobbed above the surface he could see the crowd that had gathered, a very worried Dumbledore standing at the front. After several long and painful seconds he finally made it to the edge of the lake. The crowd split and he hauled a now unconscious Tonks onto the edge. She was whisked away by Madam Pomfrey. He slowly started to sink into the lake once she was safe, he no longer had the energy to keep himself afloat. Suddenly he was flying out of the water and the sensation of the bitter cold wind beating his frozen body made him painfully awake. He landed on the ground with a gentle thud and a loud groan. Dumbledore stood over him.

"You've done well Severus. The girl is safe." The Headmaster smiled warmly before all went black.

I hope you enjoyed! Certainly more to come, I know there isn't much right now. Give me time.
