two days later
Sophia ducked as Sherlock twitched his wrist, making the silver blade slip out of its sheath on said wrist.
"Stop twitching or I'll never get it to fit" Sophia scolded him, retracting the blade and adjusting the straps accordingly.
"It's not as comfy as you promised, I have reason to squirm. Ow!" Sherlock shouted as John kicked the back of his leg.
"You're lucky she's helping you at all, especially after you almost shot her when she tried to teach you how to use the hidden gun" the werewolf informed the Hunter.
"As for it not being comfy, I told you it was a prototype, but I've seen you fight and you need one, especially with your love of disguises and the inability to always carry your normal knives or a gun" Sophia added.
"I can fight well thank you very much" Sherlock replied.
"From a distance, yes. You're the best at throwing knives I've ever seen, but once you throw them you don't have any to defend if a wolf pounces and tries to rip your throat out. Yesterday's fight proved that an this is the counter-measure" Sophia retorted as she fastened the final strap. Sherlock snapped his hand back and the blade slid out of it's place, resting against the palm of his hand.
"Now, do you think you might beat me today?" Sophia questioned with a smirk as she pushed the coffee table back, making room for her and Sherlock to move. John folded his newspaper over and watched the sparring match with interest, even Eve walked away from the microscope to watch.
Three minutes later Sophia floored Sherlock and had her own hidden blade at his throat with her gun over his heart. She radiated smugness as she let the Hunter get to his feet, quickly deflecting his wild strike with his normal knife and returning with a jab to his arm.
Sherlock dodged quickly and tried to take Sophia's legs out from under her, but only succeeded in knocking himself of balance. He fell into his armchair with an 'oomph' and Sophia laughed at his shocked expression.
"She's lived around werewolves Sherlock, she knows how to hold her ground. We trained her after all" John muttered as Sherlock got to his feet again and started to circle Sophia.
"Thanks for the reminder John, not that I needed it" Sherlock attacked as he spoke, but Sophia dodged it easily and pulled her sword out of the folds of her coat, using it to split the back of Sherlock's shirt as his momentum carried him past her.
"Not in the rules Sophia" Sherlock said as he turned to face her. He pushed her sword tip off his chest and she brought it up to deflect the knife he pulled out of his pocket. John and Eve grinned as they watched the fight progress and become more dangerous.
Sherlock proved this point when he threw a knife at the opening door and it embedded itself in the wooden frame not two inches from Mrs Hudson's face.
"Sorry, instinct" Sherlock muttered. This distraction was all Sophia needed and she placed her sword at his throat and her gun directly in line with his heart.
Sherlock smirked and hit the back of Sophia's hand, causing her to drop her sword. He caught it and turned to her, only for her to knock him on the ground mid-turn. Sophia placed her foot on his chest as she regained her sword and slid her gun out of it's holder on her wrist.
"I win, again. How many times must I beat you before you learn, you can't touch this" she told him with a cocky smile as she walked away. Sherlock grinned and grabbed her ankle, pulling her to the floor.
"Never turn your back on your enemy unless they're dead" Sherlock lectured as he put a knife to her throat. Sophia's shock evaporated and she began to laugh.
"Okay, I deserved that. And you're finally learning! You win this one, now let me up" she told the hunter. Sherlock grinned like the Joker and got to his feet, putting a foot on her shoulder to keep her down.
"Oh no, you're not going anywhere, not yet anyway" Sherlock told her. Sophia winced as she tried to lift his foot.
"Let the girl go Sherlock, you've won" Mrs Hudson ordered. Sherlock shook his head and grinned down at Sophia.
"You are going to tell me how you hid your weapons so cleverly, only when you agree will I let you go" Sherlock explained to the teen grimacing under his foot. Sophia nodded quickly and Sherlock released her, allowing her to sit up. She put a hand to her shoulder and hissed in pain, pulling it away to show it covered in blood.
"Bugger, I thought as much" she grumbled to herself as she pulled her coat off, followed by her small black waistcoat to reveal the blood soaking the pink shirt underneath.
"Did I just do that?" Sherlock questioned, looking rather guilty. Sophia shook her head and got to her feet.
"No, you didn't damage the stitches or pull the bandages off, I've done that myself in the past few days. I managed to stop the bleeding last night, but it looks like our little sparring match has started it off again" Sophia explained as she walked into the kitchen. She grabbed the first dark and uncharred tea towel she could find and placed it on her shoulder, applying pressure to it as she dropped onto the sofa.
"I will teach you how to conceal your weapons in your clothes like I can, it works best in jackets and suits. That waistcoat is an example, be careful when you pick it up" Sophia told the Hunter as Eve walked back to her microscope and John looked back to his newspaper.
Sherlock picked Sophia's small black waistcoat up carefully and placed it flat on a pile of clutter on the coffee table. Sophia pointed to a practically invisible pocket on the waistcoat, which held three extra blades for her wrist devices.
"The ones I have... Well lets just say I've had to pull silver alloy blade slices out of my wrist before, along with a silver bullet, so I learned to keep a few spare. The blades are pretty easy to change actually when you get used to doing it" Sophia answered Sherlock's questioningly raised eyebrow. Sherlock smirked and handed her one of his knives.
"Replace it if you wish, I know you put a silver blade in mine, but yours will still- wait a minute, did you just say you pulled a bullet out too?" John raised his eyebrows at Sherlock's offer to Sophia, but he almost laughed at the drastic change in Sherlock's thought. Sophia only nodded and pulled the Hunter's wrist closer, almost causing him to collapse on the table.
"When it is hidden in it's sheath it's pretty much bulletproof, with the right blade anyway" she explained as she took it off the Hunter's wrist. Sherlock nodded and pulled the coffee table back into it's normal place.
