(A/N) For my dear Watson as always. You've inspired this story which is starting to get slightly out of hand I think. Another update after copious amounts of tea to keep me awake.

Lady A: I'm sure it is brilliant as always. *sips her tea*

Lock: *shrugs* Quite possibly. You'll have to be the judge though. *sits back in her prayer pose*


Third Person POV

"Wait hang on, are you two actually going to look for an Angel?" Amy asked the consulting detectives as the others caught up with them. "You have been listening right?" The Scottish woman asked them as they walked through the halls of Buckingham Palace as if they owned the place.

"Yup," Lexi said, throwing a grin over her shoulder at the redhead.

"Then why would you be looking for one?" Rory asked them in confusion and the two detectives stopped walking and turned around to look at the others. Mycroft had followed after them as well and he had a deep frown on his face as if he didn't approve of the situation.

"For the same reason we look for serial killers and other murderers, to solve the case," Lexi told them and Sherlock sighed beside her. They weren't being serious right?

"Obviously," Sherlock said, looking away from them and Lexi patted his arm which seemed to get him to calm down from whatever… thing that was going on with him.

"You can't go looking for the Angel!" The Doctor shouted as he pushed past Amy and Rory to the front and stared at the two detectives, Lexi raising her eyebrow. "Angels are bad. Bad, bad Angels. We stay away from the Angels," The Doctor told them waving his hands around.

"I must say I agree with him. I forbid you two from going to look for the Angel," Mycroft told them and the Doctor turned back around and pointed at Mycroft and then the detectives, nodding in agreement.

"You forbid it? Going to tell Mummy?" Sherlock snapped and Mycroft sighed as the Doctor and his companions watched the brothers in confusion.

"Boys," Lexi warned and they both snapped their heads to look at her. "Fighting isn't going to fix things right now, only make it worse. You two get along or I will be calling Mummy," Lexi told them and they watched as the brothers paled slightly and backed down before Lexi turned to the Doctor. "The Angels are behind the killings, right?" Lexi asked him and the Doctor nodded in confirmation. "Then we need to find the Angel and stop it," Lexi told him and the Doctor shook his head.

"A Weeping Angel is the deadliest, most powerful, most malevolent life form evolution has ever produced and you want to go looking for it?!" The Doctor asked the Irish girl incredulously as River smirked beside him, impressed.

"Well like you said, they're stone when you're looking at them," Lexi said as the Doctor looked back at her blankly and she sighed. "There are more of us then there are of them. We take turns all staring at the statue to keep it as stone and then someone destroys it. Case closed," Lexi told them as Sherlock smirked beside her when the Doctor opened and closed his mouth like a fish.

"Yeah, why haven't we thought of that Doctor?" Amy asked him as she turned to him and grinned when she saw the Doctor's impression of a goldfish.

"Because…because…," The Doctor said before he threw his hands in the air. "Because that's not how it works." The Doctor finished, pointing at the detectives who smirked back at him.

"Are you sure, cos that sounds like it would work," Amy said, grinning at the Doctor who was getting flustered by the two detectives. She hadn't seen anyone actually do that to him before besides River. The Doctor pointed at Amy and sputtered as the two detectives turned around and started walking again. Mycroft looked at the group and nodded one before he brushed past them and followed after his brother and the Irish girl. "Are you Mr. Grumpy Face again today?" Amy asked the Doctor who did in fact look grumpy.

"Yes, Amy, I'm definitely Mr. Grumpy Face today. The last time we faced the Angels we lost people, good people," The Doctor said looking off down the hall that Sherlock and Lexi were still walking down followed by Mycroft. In truth, the Doctor didn't want to lose anyone else. He could see that Sherlock and Lexi were both brilliant people, good people. "Come along Ponds," The Doctor said with a sigh as he followed after the two detectives. If he couldn't convince them to not go after the Angel he could at least make sure that they didn't get into trouble. They both seemed rather stubborn. "Alright fine, we'll look for the Angel," The Doctor said as the group caught up with the detectives. "But no wandering off. First rule," The Doctor warned them and Lexi grinned slightly and nodded.

"Croft can you control the situation while we take care of this?" Lexi asked Mycroft who looked at her for a long moment before he nodded and walked away.

"Do be careful, won't you?" Mycroft asked her and Lexi nodded, smiling at him softly.

"Always," She told him as Sherlock nodded curtly. The British Government left them after one look over in the Doctor and his companion's direction. The Doctor pulled out his sonic screwdriver and flicked it on. Find the source of the signal and most likely find the Angel as well. "What is that?" Lexi asked him and the Doctor looked over at her briefly as she gestured to his sonic screwdriver.

"Sonic screwdriver," The Doctor told her and she giggled causing Sherlock to look down at her fondly. It was apparent to the Doctor that Sherlock and Lexi were fiercely loyal to each other and that Sherlock loved nothing more than making sure Lexi was safe and happy.

"Who looks at a screwdriver and thinks, 'this could use a little more sonic'?" Lexi questioned him with a snort and the Doctor looked over at her and opened his mouth before closing it, his face screwing up in minor offense.

"Don't dis the sonic," He told her, pointing at her and she raised an eyebrow. "Now, the signal is originating from somewhere…there," The Doctor said, pointing down the hall before he looked back at the Ponds. "Amy, Rory, stay close," He told them and they both nodded as River took out her blaster and dialed in the settings grinning slightly back at the Doctor. The group moved out, following the signal until they made it to some stairs. They started down them together, the Doctor going first and closely followed by the two detectives. As they walked down lower it started to get darker. The two detectives pulled torches out and turned them on as they walked out to an eerie cellar. Apparently this was the part of the tour they didn't tell you about. The dark cellar that could potentially contain a deadly Angel statue. The Doctor stopped them from going any further, not liking this situation. He was getting too many flash backs to the dark catacombs and all of the statues that were actually Angels. "Ah ah, bad, very bad," The Doctor said, scanning again. The signal was coming from somewhere ahead of them.

"Afraid of the dark?" Sherlock asked the Doctor with a slight smirk. "How very telling," He continued and the Doctor looked back at him as Lexi gave him a pointed look and raised her eyebrow.

"Lock," She warned before she looked back at the Doctor. "What's wrong with the dark?" She asked the Doctor, but River was the one who answered her as the woman moved closer to the front of the group.

"It's not the dark sweetie. It's what could be in the dark," River told her and Lexi nodded and pulled her blaster from her leg and held it up.

"Then we should go first," Lexi said and both the Doctor and Sherlock shouted "No!" at the same time. "Do you have another suggestion then?" Lexi asked the Doctor and Sherlock, looking between the two of them.

"You give me the gun and I go," Sherlock told her and she shook her head at him.

"No, I've been trained how to shoot, you haven't," Lexi told him and Sherlock sighed loudly. "This isn't Moriarty," She told him and the Doctor watched as Sherlock growled slightly at the name.

"You are not going in there without knowing what we are up against," Sherlock told her and Lexi sighed as everyone just watched their argument. They argued like and old married couple.

"You're the ones who wanted to go after the Angel," Amy pointed out and the two detectives turned and looked at the Scottish woman. "Well you are," She said when they both gave her a look.

"Yes, well…," Sherlock said as Lexi nodded.

"Exactly. So, River," Lexi said and the blonde moved forward to Lexi's side and pointed her blaster forward. Lexi raised her own and both women started forward, side by side, scanning the dark cellar. The Doctor and Sherlock exchanged a look before they followed after the women, Rory and Amy carefully following after them. The girls covered the room and the Doctor was slightly amazed with the fact that Lexi was standing it a stance similar to River's. It showed she had training like she said. He directed the girls forward and they all froze in place when something crossed in front of the beam of light in front of them. River and Lexi's fingers tightened on the triggers of their guns as they readied for a fight. "What was that?" Lexi asked River and she shook her head.

"I don't know," River told her as they scanned the room carefully. "Keep your gun ready," River told her and Lexi nodded.

"Planning on it," Lexi told her as both women took a few cautious steps forward. They saw the thing move again and River and Lexi both fired at it, missing it.

"Dear God its fast," River said as the Doctor raised his hands and pointed behind him as Amy and Rory backed up slightly behind him and Sherlock.

"Maybe we should," The Doctor suggested but River and Lexi advanced forward, Sherlock carefully following them, keeping close to Lexi. The girls moved and blasted again as soon as something moved again in the shadows.

Suddenly they heard a loud noise, almost like the buzzing of insects and Lexi dropped her blaster and torch. They crashed to the floor as she turned around and everyone saw these silver bug like things crawling up her chest. She tried to shake them off but they clung to her and kept moving. Sherlock moved towards her but River quickly grabbed him and pulled him behind her as she trained her blaster on Lexi just in case. The Irish girl threw her head back and groaned as the buzzing sound grew higher pitched to sonic levels. She jolted forward and they all saw the metal components on the right side of her face that had blue lights flashing on it every few seconds. They heard Lexi laugh breathlessly as the Doctor waved his hands in the air.

"Ah ah, very not good, very, very not good. Very bad,' The Doctor said, pointing to Lexi who wasn't moving.

"What is that?" Amy asked the Doctor as River continued to hold the struggling consulting detective back.

"You can't!" She finally told him and Sherlock stopped struggling and glared down at her.

"Why not?" He snapped and River put her arms on both of his and looked up into his eyes, not at all fazed by his attitude. She was used to the Doctor getting over emotional in situations like this.

"Because right now that isn't Lexi," River told him calmly before the Doctor took over and answered Amy's question at the same time.

"Cybermites, components of a Cyberman, they've taken over her brain," The Doctor told them as Lexi suddenly lifted her arms and looked down at them before touching her face.

"Oh lovely, incorporated. Yes. Ah. Nervous system is hyperconductive. Remarkable brain processing speed to. Woo hoo this is amazing. Not your average human. Brain is far more advanced," Lexi said quickly in a voice not her own before her head snapped to the side.

"Get out of my bloody head!" Lexi cried her voice becoming her own once again and taking on her Irish lilt.

"That's not possible," The Doctor said, pointing to Lexi. "She's fighting against it," He said as Lexi's head snapped forward again and she rubbed her hands together as Sherlock watched her carefully, his face pale as he looked at the girl that looked like Lexi but wasn't acting like her.

"Oh, this is brilliant. I'm so clever already, and now I'm a million times cleverer. And what a brain. Human, but not like a normal humans. So much raw data. Deductions and deceptions. She is rather clever, solving all those cases. And ho ho…," Cyber Lexi said before her head snapped to the side again.

"No, that you don't get to see. Stop rummaging around in my mind," Lexi said as the Doctor, the detective, and the companions watched her in confusion.

"Just try and stop me," Cyber Lexi said before Lexi took over again.

"I sort of think I am already," Lexi said and the Doctor's mouth fell open in shock. She shouldn't be able to block the Cyber components out, to take over control for however brief a moment. The Doctor suddenly remembered the scans he had taken of Sherlock and Lexi earlier. Their neuron activity was far faster than any human he had ever scanned before. It was like their brains worked faster. The Cyber component said her brain was far more advanced than a normal humans. Maybe that was how she was controlling it.

"You only think you are. Fascinating. A complete mental block. Hiding away your , relax. If you just relax, you will find this a perfectly pleasant experience. You are being upgraded and incorporated into the Cyberiad as a Cyberplanner," Cyber Lexi said and the Doctor frowned. That was very not good and potentially very bad.

"Get out of my head!" Lexi said as she took control over again before the Cyberplanner took over again.

"Oh, Sherlock. You are think about him a lot. Why?" The Cyber Lexi asked and Lexi took over again.

"Enough," She managed to get out before the Cyber Lexi took over again and chuckled.

"Poor little Lexi. Someone has had it hard. Nearly died several times too," Cyber Lexi said and the Doctor looked slightly surprised by that. She just didn't look like the sort of person who would be in danger despite her job as a consulting detective whatever that really was. "Moriarty. You're afraid of him. It appears we are at a stalemate, then. One of us needs to control this head. We're too each control forty nine point eight eight one percent of this brain. Point two three eight of the brain is still in the balance. Whoever gets this gets the whole thing," Cyber Lexi said before Lexi took control again.

"I propose a takes all. Nobody can access that portion of the brain without winning the game. I win you get out of my head," Lexi said before the Cyber Lexi took over again.

"And when I win I get full control over your brain and body. You can't win," Cyber Lexi said and then the real Lexi took over with a look of determination on her face.

"Try me. There's one thing no one ever puts in danger if their smart and that is the people I care about," Lexi said her eyes flashing up to Sherlock and she nodded at him. He nodded back at her and a wordless understanding passed between them. "My mind against yours," Lexi told the Cyber Lexi who took control over again.

"It's like you are letting me win then. This is going to be the most efficient Cyberplanner. Not a great name, that, is it?" Cyber Lexi asked, looking up at the group who was staring back at her. She grinned and held her hand out. "Hello, I'm Miss Clever," She said before laughing as Sherlock, the Doctor, and the Ponds looked at her in horror, the consulting detective wondering if he had lost the girl he loved.
