Sherlock sits on the floor with his back against the wall, his legs bent up in front of him and his wrists rest on top of his knees. His head is lowered and staring at the floor in front of him, breathing heavily with a distressed look on his face.

Mycroft stands by the open door, watching his brother. You pull away from John's shoulder as he starts to walk across the room, avoiding the splintered wood lying around, and bends down to pick up the pistol from the floor.

He clears his throat and said. "Look, I know this is difficult and I know you're being tortured, but you have got to keep it together."

"This isn't torture; this is vivisection. We're experiencing science from the perspective of lab rats." Sherlock said, not lifting his head. John grimaces then turns to you then looks back at Sherlock. "Mycroft, I think we need to give them a minute, alone." John said to Mycroft, who nods, and they head towards the doorway, leaving only you and Sherlock alone in the room.

You look around the room before you walked over to Sherlock and squated down next to him. You place your hand over his and he lifts up his head to look at you. "I'm so sorry, (y/n). I...." He started to say but you shake your head. "Don't be sorry. You did what you thought was right. I'm not mad at you." You said. Sherlock stares at you for a moment and placed his hand on your cheek, his thumb stroking it.

"I don't deserve you." He whispered.

You chuckled and said. "That's funny."

"Why?" He asked.

"Because that's how I feel everytime I look at you. I feel like I don't deserve you." You replied.

The two of you stare at each other for a moment before you stand up and hold your hand out to him. He swallows and looks up at you and said. "Soldiers?" You smile and nod. "Soldiers." You stated. He smiles and takes your hand and you help him to his feet.

He takes your face in his hands and leans down and gives you a soft, sweet kiss. "I love you." He said, softly. "I love you, too." You said and the two of you walk towards the door.

"Tick-tock, tickets please!" Moriarty's voice said over the speaker as the four of you walk into another grey walled room with a screen and John hands the gun back to Sherlock.

The strange thing about this room is that there was nothing in this room. "Hey, sis, don't mean to complain but this one's empty. What happened? Did you run out of ideas?" Sherlock asked. The screen flickers on and show Eurus's face.

"It's not empty, Sherlock. You've still got the gun, haven't you? I told you you'd need it, because only three can play the next game. Just three of you go on from here; your choice. It's elimination round. You chose two and kill the other. You have to choose family or friend or love. Mycroft or John or (y/n)?" She said as Sherlock turns to face the three of you and the lights go red again and Moriarty's face appears on screen and he makes ticking sounds again.

"Eurus, enough!" Mycroft shouted as the lights turn white.

"Not yet, I think. But nearly. Remember, there's a plane in the sky and it's not going to land." Eurus said as she appears on screen again, smiling. Mycroft rubs his hands over his face and lowers them and steps forward towards Sherlock. "Well?" He said. "Well, what?" Sherlock asked.

"We're not actually going to discuss this, are we?" Mycroft asked him. He turns his head towards John and said. "I'm sorry, Doctor Watson. You're a fine man on many respects." Then he turns back to Sherlock and said. "Make your goodbyes and shoot him." Your eyes widen and you look over at Mycroft as he points at John and shouts. "Shoot him!"

"What?" You and John asked as John walks closer to him.

"Shoot Doctor Watson. There's no question who has to continue here." Mycroft said.

"Hang on a moment, doesn't John get a say in this?" You asked as Mycroft looks over at you.

"Or you could shoot her." He said.

"What?" John asked, angrily, as you stare at him.

"Whatever lies ahead requires brainpower, Sherlock, not sentiment." Mycroft said.

"What the hell, Mycroft?" You said, angrily.

"Today, we are soldiers. Soldiers die for their country." He said.

"Shit. He's right. I'll do it. I'll take the bullet." John said.

"Are you mad?" You ask him.

Mycroft gives a small smile, turns to Sherlock and said. "Good. Make it swift. No need to prolong his agony. Get it over with and we can get to work." John shifts on the spot and straightens up, bracing himself. Sherlock lowers his head and half-turns away.

Mycroft scoffs and starts to chuckle, sarcastically. "God! I should have expected this. Pathetic. You always wear the slow one....the idiot. That's why I've always despised you. You shame us all. You shame the family name. Now, for once in your life, do the right thing. Put this stupid little man out of all our misery." He said. John bites his lips but Sherlock doesn't move.

Mycroft rolls his eyes then turns to you. "Fine. Don't shoot Doctor Watson but how about you shoot (y/n)." He said. Sherlock looks over at his brother and glares at him.

"She's nothing more than a distraction; a little scrap of ordinariness for you to impress. And the child she's carrying will be a disgrace to the family name." He sneered.

"Please, for God's sake, just stop it!" Sherlock said.

"Why?" Mycroft asked.

"Because, on balance, even your Lady Bracknell was more convincing." Sherlock said.

Mycroft blinks and lifts his head, looking a little disappointed. Sherlock turns his head towards you and John and said. "Ignore everything he just said. He's being kind. He's trying to make it easy for me to kill him. Which is why this is going to be so much harder." He turns to Mycroft and raises the gun, pointing at him.

"You said you liked my Lady Bracknell." Mycroft said with a smile.

"Sherlock. Don't." You whispered.

Mycroft turns to you and said. "It's not your decision, (y/n)." You and John look at him as he turns back to Sherlock.

"Not in the face, though, please. I've promised my brain to the Royal Society." He said.

"Where would you suggest?" Sherlock asked him.

Mycroft starts doing up the top button of his shirt and straightens his tie as he says. "Well....I suppose there is a heart somewhere inside me. I don't imagine it's much of a target but....why don't we try for that?" He lowers his hands and looks directly at his brother as John holds his hand out towards Sherlock and said. "I won't allow this."

"This is my fault." Mycroft said as he turns to face you and John. Then he turns back over to Sherlock and said. "Moriarty."

"Moriarty?" Sherlock asked.

"Her Christmas treat: five minutes conversation with Jim Moriarty five years ago." Mycroft replied.

"What did they discuss?" Sherlock asked as he lowers the gun.

"Five minutes conversation....unsupervised." He said.

John's mouth opens and he stumbles back a step as you look over at him in shock. Sherlock sighs softly and raises the gun again. "Goodbye, brother mine. No flowers......by request." Mycroft said as he straightens up and puts his hands behind his back.

"Jim Moriarty thought you'd make this choice. He was so excited." Eurus said, breathlessly.

Then the screen switches to Moriarty's face and he begins to speak. "And here we are, at the end of the line. Holmes killing Holmes. This is where I get off." He said woth a small smirk then the screen switches back to Eurus as Sherlock, looking grim, glares at his brother.

"Five minutes. It took her just five minutes to do all of this to us " He said, through clenched teeth.

He turns his eyes towards John then over at you and the two of you lock eyes for a moment. Sherlock returns his gaze to his brother, then raises his eyebrows and shrugs, pressing his lips together for a moment before lowering the gun and turning away.

"Well, not on my watch." He said.

"What are you doing?" Eurus asked as Mycroft looks over at him startled.

"A moment ago, a brave man asked to be remembered." Sherlock said and you and Mycroft look at him, alarmed.

"Sherlock, no, please." You begged as he looks over at you and said. "I'm remembering the governor."

Holding the pistol in both hands, he lifts the muzzle and presses the end under his chin. "Ten..." He said as Eurus frowns and shouts. "No, no, Sherlock."

You place your hands over your mouth as John looks over at Mycroft then back at Sherlock.

"Nine....Eight...." Sherlock continues.

"You can't!" Eurus shouted.

"Seven...." Sherlock said.

"You don't know about Redbeard yet." Eurus said, urgently.

You, John and Mycroft stare at Sherlock in horror as he lowers his left hand, continuing to hold the muzzle under his chin with the other.

"Six...." He said.

"Sherlock!" She shouts, anxiously.

"Five...."

"Sherlock, stop that at once!" Eurus shouted in a panic.

As she yells, a small dark whizzes out of a round hole in the wall and impacts the back of Sherlock's head. He jolts and reaches his left hand round to it.

"Four...."

Another dart hits John in the back of the neck and a third one hits your neck as well. You and John reach around for it while Sherlock pulls the dart from his neck.

"Three...two..." He said, weakly, and he slowly falls backwards, pistol falling from his hand.

You and John pull the dart out of your own neck and you immediately follow suit with Sherlock and fall backwards into darkness.
