A/N - I’m certain most of you will love this story as from the feedback from the sibling stories. It’s something you’ve been waiting for. I kinda added some more things to eurus too. Enjoy. @redheaded-hobbit @fanfictionsilove love all u huge credit to @bakerstreethound for basically giving me an amazing dialogue and action scene with Moriarty and the shot, couldn’t have done any better. Check out her works if you love Sherlock ❤️
You skipped up the steps to Sherlock’s flat and burst through the door. He sat on his usual chair. John stood next to him, pacing. Your brother locked eyes with you.
“Did you know?” He asked.
You shook your head. How could you know you had a sister? You’ve had no memories. All you remembered were your brothers, much smaller.
“Did Mycroft tell you anything else?” You asked, walking closer to him. Sherlock’s eyes gave way into his thoughts. He was concentrating, processing a plan.
“I know where she’s at. I got a summary and went on from there.” He squinted his eyes. “Did you get anything else?”
You pursed your lips. “Maybe. Tell me what you have first.”
Sherlock breathed hard. “Master mind. She’s connected with Moriarty. Went to Sweden then the states on multiple jobs, developing a base. In prison now. She was a scientist, worked in chemistry.”
“Like you,” John said, looking at Sherlock.
“She’s involved with Moriarty, however I think he’s tricked. Multiple disguises. You’ve seen her already,” you faced John, “you have too.”
A confused look spread across his face. “I have?” He asked.
You nodded. “She’s good at this.”
“I don’t doubt that she was behind some of Moriarty’s plots. Lestrade has a hit on something else. Threats on the prime minister. They’re talking about a bomb. I went over and spoke with him. It’s Moriarty’s work.” Sherlock said, looking up at the ceiling. He was stumped, which was quite odd for him.
“We have to stop her. Break the connection. Find out her motives. We couldn’t possibly know.” You said. John sighed and lightly cursed under his breath.
“Threats to the government. Perfect,” John huffed.
“She’s using him,” you added. You already knew it. Moriarty was merely a puppet. His only flaw was his trust. It was too easy. She offered him momentary pleasure. He was easy.
“We’re going to go see her.” Sherlock said, standing up and walking to the kitchen. You followed him.
“You’ll see.” Sherlock said, putting on his coat. You walked out the door with Sherlock. John followed behind. He called for a taxi. One came sprinting by and you hopped in with everyone.
“Waterloo station.” Sherlock said.
The train took you from London to Wales. The skies were dark with dismay. John still looked confused.
“I’ll see you there?” You said to your brother.
He nodded. “Stay on time.”
“(Y/N)!” Sherlock called. You turned around.
“Be safe.” He said. You smiled at them. You weren’t exactly the best at being safe.
Danger was in your blood. You could sense almost everything, but you couldn’t always sense danger. Most times, you placed yourself in it. You didn’t know why, but thinking about it led you in a loop, undiscovered.
You continued walking onwards from the station and turned around. Sherlock and John went the other way, their bodies soon became lost with the people. You called for a taxi which took you further up the bay, closer to the water. You toyed with your nails, couldn’t refrain from thinking about Eurus. Did you share any traits with her? Were you similar? Was she like you? You knew about her disguises, but you never knew what she looked like. She was manipulative. You could only elaborate on that. You were eager to find out more, pieces together the missing remnants of your childhood. You hopped out of the taxi after paying the driver. You were much closer to the water now. Dark waves hit the stone supports harshly. Small boats were on the water. You scanned the abyss.
“Got it.” You said to yourself.
The small distinct cargo ship you were told to look for was parked and getting ready to leave. You quickly looked around and saw a construction vest and a few jackets hung over a rail near the ship. You walked to it and swiftly grabbed the vest, putting it on in one move. You messed up your hair a bit and shirt, trying to look worn. You were wearing a pair of black palazzo pants and heels which made you rethink your plan. You walked up to the side door of the ship. A man stood pacing around on his phone, smoking a cigarette. He looked up at you when you walked inside.
“I left a few tools in the back from before. Management asked me to get them real quick.” You looked at him and smiled, trying to radiate your charm.
“Sure, sweetie. We leave soon, just so you know,” The man said.
“I’ll be out before you know it.” You winked at him which caused him to shake his head and blush.
You began walking around near the back, pretending to know where you were going. You opened another door, which lead to a series of steps to the keel. You closed the door and walked down. There was ship machinery in every corner. You wiggled through some engines and sat down on a spot between two. You were certain no one would see you here. You waited six whole minutes until you felt the ship start moving. You sighed in relief and patiently waited. Trying to pass the time, you tried to envision Eurus which was difficult. All those deceptive things she did made you question your lineage. You were nervous for what you were about to do. Spying, solving cases, software, criminals - it was all in your blood, but you felt particularly nervous today. You hadn’t done anything like this before. Your mind went over to Mycroft. You decided that he wouldn’t be much help to this. Thinking about Sherlock and how you were on the same waters now comforted you. You leaned your head against the engine behind you. Your eyes closed, but your unconscious intuit didn’t subside.
You woke up from a quick doze, hitting your head on the engine you were against. The ship stopped, causing you to move forward.. You quickly stood up and walked up the sharp stairs. You had to be careful. You couldn’t be seen.
You opened the door and poked your head out, scanning your surroundings. Seeing that no one was nearby, you walked out and opened the main side door. No one was outside yet, which gave you time to run out. You sprinted across the sand and nudged your body on the side of a cliff, hidden. You took off your vest. You didn’t look at the prison in details, but you noticed the sad stone walls. The prison was on top of the mossy stretched cliff.
You peeped your eye out of your hiding and saw a man walking out of the ship. You didn’t see him before. He carried boxes and wheeled a larger box out. You knew they were all supplies. The man boarded back on the ship which started the journey back under watchful eyes from the security. You put half of your body out of the cliff and waited until a few men walked out to pick them up. They were security, but acted casually, now that the ship was out of sight. They walked up the steps. You sneaked up behind them and stepped to the side before they stepped in. After the last man walked inside, you grabbed the door handle right before it closed. You angled your body to reach the combination code pad. You squeezed it a certain way, just how you’ve done countless times before, which enabled it to open and reveal the colorful wires activating it. You stretched your body further to spark two wires. Immediately after doing so, red lights and a light buzzer began flashing and going off inside and outside. You opened the door and walked inside casually. A few security guards jogged down the hall. You walked past offices and an occasional guard, who paid no attention to anything except his cell phone. You maintained a confident posture and gaze. No one even saw you.
You didn’t know where Sherlock was, but by analyzing the design and structure of the building, you had an idea where Eurus’s cell was. You walked down the staircase and through the hallway. As you were walking down, a door slammed open immediately and out came Sherlock and Mycroft - Mycroft? A second later came John and a man with a suit. Sherlock noticed you first.
“Well done. I was getting worried. As soon as I heard the alarm, I knew.” He said. Sherlock was in a better mood. You knew he was alert. Highly alert. He was excited. It was as if he was almost built for this, and you as well. The red lights and alarm stopped.
“Mycroft? What are you doing here?” You asked, trying to maintain your composure. He wore a suit, directly coming from the London.
“Enough with that. He had full intention to come here on his own to handle this situation by himself.” Sherlock said.
“You’re unbelievable. You don’t trust us. What would your plan be to get around this?”
“This is what I was trying to avoid. I am the government who is taking great care of those threats. How did you even get in?” Mycroft asked you, scoffing.
You rolled your eyes at him. “Do you not know anything about me? You always do this.”
Mycroft sighed and seemed sincere. “I’m sorry.”
Although Mycroft and you were different, you still shared similarities, and it wasn’t only blood. He was always tender to you and didn’t usually yell, like Sherlock. Mycroft never really treated you like mutual. You were still trying to find out why, possibly because you were merely his sister.
“There are memories.” You said.
“Blank ones. I’m aware. I’m sorry. Surely, you can try to understand why.” He replied, rubbing his temples.
“There are more important things to do. I know,” You added.
“I’m leaving.” Sherlock called out. You looked at Mycroft again, then ran up to Sherlock and followed him. He walked up the staircase and down the hallway, making a turn to the right. He opened a door which led to a blank room. Your heart began to beat faster. You knew what was through the other door. You beat him to it and swung the door open. There, in a glass wall was your sister, Eurus, playing a violin. You stood still, wrapping your head around her. Your mind naturally tried to analyze and inspect everything, but you couldn’t figure anything else out about her. Sherlock moved you aside and walked inside, next to you.
John came inside, but Mycroft wasn’t here. Eurus stopped playing and looked at everyone. She locked her eyes with you.
“Sister,” She said. “How much you’ve changed.” Her voice was soft. She possessed a kind demeanor, but underneath it, you sensed desperateness. Evilness. Intellect. Eurus looked at Sherlock.
“Hello, Eurus,” Sherlock said. Eurus’s expression didn’t change.
“Where is Mycroft?” She asked.
“Not here.” Sherlock said.
“No, silly. I know he’s here.” Eurus turned around and began walking in a circle.
Sherlock walked closer to the glass. “Eurus, what are your plans?”
Eurus walked closer. “Don’t you know them?”
“You’re with Moriarty. Why? What can you give him?” Sherlock asked. He thought hard. “I know about your plans with the government.”
Eurus looked at him. She wasn’t surprised. “It’s mutual. I gave him ideas.”
“Are you thinking about Redbeard?” Eurus asked. Sherlock didn’t say anything.
You were finally starting to understand everything. “You can give him something else.”
Eurus looked at you and smiled. You knew it all.
You walked out of the room and began running as soon as you entered the hallway and sprinted up another flight of steps. You passed by a glass office, covered by an entirety of glass walls and windows. The abyss of the ocean lay idle in your vision. There, you saw Mycroft sitting on a chair. You opened the door. He looked up at you, but didn’t say anything. Something’s wrong.
“What is it?” You asked. He didn’t look up. You walked closer to him and breathed hard when you saw what was on the floor. A man, recently shot, was dead. Blood poured from his stomach.
“What happened?” You asked him. Mycroft stayed silent. You put your hands on his shoulders and shook him. He looked up at you finally and stared you in the eyes. Then you knew.
You turned around. There he was. He wore a casual silver suit and had a glimmer in his eyes. He was confident, ready, excited. He stood by the door straight up. You scanned him without even moving your eyes. He had a gun, but he didn’t hold it.
“It’s so great to see you here!” He exclaimed. You didn’t say anything. Your mind moved quickly, planning your next move. You knew his intentions.
“I’ve finally outsmarted you.” He said.
You stood up and walked closer to him.
“(Y/N),” Mycroft said. You ignored him.
Moriarty adjusted his shoulders and stood up straighter. You kept eye contact with him.
“What are you going to do?” You asked him, trying to make him think you were ten steps behind.
“What would be the fun in giving that away?” He leaned closer to you, touching your neck.
You opened the door and walked out. Just like that. You knew he wouldn’t shoot you. He was enjoying this. You walked by an alarm and stopped. You opened the alarm case and sparked two wires, the same process you did earlier. You punched in a code. An alarm went off, fulfilling your next plan. You ran downstairs and walked into the room where Sherlock and Mycroft originally were. You knew there was a weapon somewhere. Emergencies. You looked up and down everywhere. You placed your hand under the table and smiled when you felt the cold metal, just where you thought it would be. You hid the gun in your waistline then walked into Eurus’s room. Sherlock rushed out, almost bumping into you, but stabilized you with his arms. A worried look spread across his face when he looked into yours. He didn’t have to ask you anything to know what was going on. He ran out with John.
You opened the door to see Eurus standing in the middle of the room. You knew what you had to do. Your mind was thinking. You acted fast and quick. No emotions played through you. You opened the glass door and entered her room.
“I never got to know you.” She said.
You pulled out your gun. She didn’t react when she saw it. You held the gun up at her.
“We were never similar,” you remarked. “I don’t want to know anything about you. I already know what I need.”
Eurus laughed at you. “You won’t win this. You do realize that?”
You shook your head. “I’ll win. I know that it comes with a sacrifice.”
She scoffed. “You give up that easily? You never did know how to think, did you?”
You walked closer to the glass and kept your gun to your side. “I know more than you think I do. You wouldn’t have a slight idea. Here you are, thinking you’re a mastermind. A perfect place to be, a prison, filling everyone with delusions. You call that winning?”
Eurus walked in another circle. “It’s working. Isn’t it? If you kill me, you’ve still lost.”
You opened the glass door and held your gun to the level of her head.
“You’re insane. Does it look like I need you? You think I do, but that’s great, cause I don’t.” You pulled the trigger, shooting her in the head. Instantly, a red dot formed and grew larger. Her lifeless body fell down immediately. Eurus underestimated you. Although you seemed more human, you weren’t. Your mind was full not even near capacity of concepts and secrets she wouldn’t be capable of attaining or understanding. She was confident you wouldn’t kill her. That’s where you outsmarted her. You knew where Moriarty’s was and his next move, but you were right before. Sacrifices had to be made. Just thinking about it caused your stomach to twist in knots.
You put the gun inside of your pants, on a hinge of your waistline and ran upstairs. You walked up the steps to see Sherlock standing away from Moriarty. Moriarty was saying something. Mycroft still sat down on the chair. John stood behind Sherlock. The alarm wasn’t on anymore.
Moriarty turned around to face you. “The gang’s all here!” He said cheerfully, pulling his gun out casually.
“Each one of you has ruined my chances of success and hadn’t even thought twice about it.” His voice shrilled. “That’s it.” He was right. We have. Delusional. You saw how Eurus messed with his head.
Moriarty walked around in a circle. “Who wants to die first? I have all the time in the world!”
“Moriarty!” John cried out. Sherlock placed an arm blocking him.
“Mycroft, stand up.” Moriarty demanded. Mycroft slowly stood up and walked out of the office, cautiously. You knew they didn’t know that Eurus was dead. You would shoot Moriarty now, but there wasn’t any more bullets left.
“I’ll save the best for last,” he said. Moriarty pointed his gun to John. Sherlock couldn’t do anything. Mycroft wouldn’t. John shrunk down in horror.
“You don’t have to do this,” John said. He was terrified. You couldn’t take a chance with your gun.
You were the smartest one to initiate the approach. John dying first would mess it up. Without any hesitation, you began running to Moriarty. You jumped up on him and tried to throw him on the ground. He overpowered you and swung you across himself hard, throwing you down on the cold floor. Your body ached, but this was the first step.
“Don’t do that again!” Moriarty screamed. You lied on the ground, motionless.
Moriarty looked at you, shocked. You were pleased. “What did you say?”
“She’s dead. Are you....slow?”
Moriarty gripped his gun tightly and pointed it to everyone. He grew angry and looked at you with pure resentment in his face. He fled down the stairs, not looking back. Sherlock ran to your side. John stood near you. Mycroft walked closer, but he began pacing.
“I have a gun.” You said.
Sherlock didn’t speak. He pulled it out of your waistline. He sighed.
“None left. It might help you”
“I’m lost, but I’m thinking,” Sherlock said.
“We’re all dying today,” Mycroft added.
“Sacrifices. You know what to do. You all do. Go,” you demanded.
Sherlock was puzzled. “Sacrifices? You can’t surely mean-.”
You rose your voice. “I know. I do. It will work. You know what to do. You have time, just go.” Your voice was soft, full of reality.
“Don’t talk like that,” Mycroft said.
“She’s right,” Sherlock added. Mycroft didn’t understand nor did John. It was as if you and Sherlock shared thoughts. He got up from your side and kissed your head before he left. He motioned the others to follow him. You leaned against the glass window. The waves smacked against the cliffs hard.
You heard quick foosteps up the stairs. Moriarty came up. Anger filled his eyes.
“You didn’t think I would do it.” You said.
“I don’t need her,” he replied. He tried to make himself believe that. Moriarty grabbed your neck, but only lightly squeezed it.
“I was saving the best for last,” he said. It was all working.
“If you kill me, what will you accomplish?” You asked, going along with your preset plan.
Moriarty chuckled. “You’ll find out.”
“Will I?” You stalled. You saw out of your eye, Sherlock’s shoes come into your vision. You didn’t look away. You stared into Moriarty’s eyes.
“You killed everyone here, for what? Eurus is dead. You want to kill us. Solid plan.”
He shook his head. “I don’t understand you. You were always there, silently judging me! You ruined me! It was never Sherlock, it was you! Justice for what?!” He screamed.
“You’re weak. You rely on others to do your work. You can’t even manipulate anyone, you’re so bad at it. You are an awful criminal.” You spoke nonchalantly which angered him even more. As much as you were scared, you felt brave.
Moriarty snarled, cocking the gun, the hot metal pressed against your skull.
“You’re no smarter than you sound.”
You swore you could feel your heart rate spike as you saw Sherlock’s shoes moving quickly met your eyesight in the split second. He stood to the side of Moriarty, behind him, working efficiently. You felt he was far away, but trusted him. Silence passed but for a moment, a silent bomb ticking with each breath that exhaled. Finally, as if it were a fine orchestration, a man you knew all too well sprinted, his mass of curls wild as he bolted to you, not before the shot rung out, slamming you harder against the wall, aiming the gun away from your head. Your mind began to spin, pulling your hands away only to look at the crimson coating your hands. Your eyes fell on your stomach, now a pool of redness. Your life played in slow motion. You saw Sherlock’s body move through the air and slam Moriarty into the glass window, causing it to shatter in pieces. Your body began to fall backwards, but strong arms pulled you back up. As your body twisted in the moment, you saw Moriarty’s body fall through the opening. Your senses came back to you. Pain filled your mind.
“(Y/N)!” Sherlock screamed. You met his eyes. He was panicking.
You looked into his eyes. “We did it,” you said. The shock numbed your pain. Mycroft and John ran to your side. Their voices were all mixed together. You felt blissful. Your mind flooded with happiness and peace. Is this really death? You doubted it felt like this. You went in and out of your senses a few times. Sherlock picked your body up, your head was snudged in his elbow. He ran fast. The ceiling changed from glass to stone as he ran quickly. Rain droplets fell on you as he ran outside.
“Where’s the boat?” Sherlock cried out. His voice was scared and cracked. You couldn’t see Mycroft. “It’s supposed to be here!”
“Where is the helicopter?! You had precise instructions!” Mycroft’s voice boomed through the phone. Your vision began to blur. It was weird. You didn’t know how you felt about this. You had no control over your body. Memories from your childhood, high school, college rushed through you. Sherlock placed you on the ground and firmly pressed on your stomach. You felt John do the same.
“(Y/N), I’m sorry. I’m so sorry.” Sherlock cried. You heard the others sob. You tried to say something, but you couldn’t. You were in bliss. You managed to move your hand and squeezed Sherlock’s jacket. He held your hands. Someone else hand your other; you couldn’t tell who. Everything happened so quickly. Memories of crimes, computers, spying, all came flooding back. Exciting times of your life - moments where you almost died, you remembered it all now.
Your vision started to turn bright white and by doing so, your body shifted through a trance of euphoria. You felt proud. Dying with dignity - it never sounded as good as it felt. You accomplished what you needed. You knew there had to be sacrifices. The whiteness grew brighter, almost as if it was blinding you. You felt welcomed as if you belonged here. Your body was gone, but your mind was undecided. You chose to stay in this state for a bit longer. You continued to hear your siblings cry for you. Sherlock slumped his body over you and hugged you tightly. In the distance, you heard a helicopter. You didn’t know how you were doing it. If you hadn’t been the person you were, you could never manipulate death.
