You're in for a long dramatic chapter here :)

John's senses kicked in as he saw his dead wife appear next to Eurus in the concealed box of hers, touching the blinking package.

"Sherlock," he said lowly. "Eurus has a bomb."

Sherlock's eyes widened slightly as the voice continued to speak in his ear, Eurus smiling happily at the thought of being reunited with another brother.

John turned to face Molly who had blood dripping slowly from her neck, Irene not leaving her unscathed by nicking it after throwing a small tantrum at not getting to kill someone.

"So, when's Crofty going to appear then?" Eurus asked, tapping the package.

"You know Mycroft. He loves making a dramatic entrance with that stupid third leg of his," Sherlock replied casually, referring to their brother's beloved umbrella.

Eurus clapped her hands gleefully, turning to the other person in the concealed box.

"How about that? We get two Holmes brothers to kill."

The person laughed, placing a ghostly white hand on her shoulder affectionately.

"That's good but I only wanted Sherlock."

"You're never quite satisfied with more, James."

Sherlock cut the phone call and stared back at his torturer.

"Moriarty," he acknowledged.

He knew that he was alive but he did not know how.

"Did. You. Miss. Me?" Moriarty drawled out, running a pale finger across Eurus' cheek, making her blush slightly at the touch.

"You already know my answer," Sherlock said, raising an inquisitive eyebrow. "How? I watched you die."

"You watched what I wanted you to..." Moriarty replied, flicking a piece of invisible lint from his shoulder. "Did you ever wonder why you felt a little dizzy?"

Sherlock laughed, realisation in his eyes. "You drugged me."

"Quite easily. It was all for this here moment. To mess with your head."

Eurus was now bored. "Let's play a game. Mycroft's taking his God awful time, isn't he?"

"What game do you want to play?" Adler asked, looking at Sherlock seductively.

The Holmes female smirked. "In this warehouse, there are many rooms. In these rooms, one of you will be placed in a room and sealed in with a code. If Sherlock manages to unlock his room and has just enough time to save one of you before my little package explodes then kudos to him, he wins the game."

"And you?" Molly dare braved. "Don't you win?"

Eurus laughed. "Of course, I win! My associates and I will be long gone before you can even say the word 'bomb'."

Sherlock now noticed that the three narcissists in the room were putting on gas masks.

"Goodnight, brother. For now..."

...

Sherlock woke up, gasping for air as he realised that he was alone in a room with a one-way window, coffin, dog bowl and a door.

"Finally!" He heard. "Wondered when you were going to wake up..."

He tried to look through the window but only stared at his depressive face as a result.

"Go on then, the first code?" Sherlock asked.

Eurus giggled. "Sherlock... there are two clues in this room. They're not necessarily going to help you exit this room but they are going to help you unlock the other two. You just have to decide which one you want to use and which door it unlocks."

"What about exiting this room?"

"That's another clue entirely."

Sherlock frowned when his eyes met the bowl then the coffin. Four words in total.

"I see the questions in your minding running. Who does the coffin belong to, Sherlock? Why does that bowl have 'Redbeard' written on it?" Eurus smiled.

Sherlock's hands brushed against the coffin as he sized it up and deduced which gender it was meant to belong to.

"Female. Unmarried. 5'4."

Eurus nodded, but he couldn't see it anyway. "Yeah and?"

"It's Molly's, obviously..." Sherlock mumbled. "What's this got to do with anything?"

Eurus giggled. "I know, Sherlock."

"Know what?"

"Everything," she whispered so gently. "Why don't you pick up its lid and read what it says, hmm?"

Sherlock hesitantly backed towards the lid and picked it up with ease.

'I LOVE YOU'

"I... love... you," Sherlock read out.

Eurus nodded. "That's her clue. Now, try and deduce John's. Pick the bowl up."

Sherlock placed the lid gently onto the coffin and picked up the bowl on the floor beside it.

"Bearing in mind, you have fifteen minutes until the bomb goes off. This clue isn't as easy as the first one."

His heart lurched. How was he going to do this? Now, he really wished that Mary was here to help him.

...

Mycroft barked orders as Sherrinford slipped into a disguise.

"You always were the one to call the shots. Even with our parents."

Mycroft glared at him. "You were too involved with the physicality of everything. Someone didn't need to get their hands dirty," he argued. "Now you know the plan?"

"From the back of my hand." Sherrinford rolled his eyes. "I still do not know why I aged quicker than you. I'm only three years younger,"

His brother chuckled bitterly. "Someone went and joined the Secret Service, didn't they?"

Sherrinford smirked. "But someone learnt how to correctly wield a gun of any type."

"Can you gentlemen not argue? We're kind of in a delicate situation here," Lestrade called to them.

Mycroft rolled his eyes and turned to face his trusted assistant, Anthea, who had just come back from time off sick.

"Any details on the whereabouts of our targets?"

Anthea nodded, pushing her hair back from her face as she inspected the red dots on the tablet that she held. "Eurus is on the top floor, Moriarty's doppelganger is in a room - waiting, I assume - and Adler's on guard. There are two other guards and Sherrinford will intercept the one on the left wing for easier and sleek access."

Mycroft inspected the positions and turned to face his brother.

"You hear? Intercept the left wing."

Sherrinford rolled his eyes. "I am not deaf, although I do have selective hearing." He slipped his helmet on and holstered his rifle, petting down his bulletproof vest. "I may not be as clever as you, Sherlock and Eurus but I do have my own talents. Coordinating a highly protected asylum and conducting an extraction operation are two of them."

"Too bad your security measures failed." Mycroft snapped.

The other brother chuckled. "That was the governor's fault. Can't I enjoy a little holiday once in a while with my latest gold digger?"

"What you do in your spare time should not put everyone else at risk. And inform your governor that the next time I see him, his contract is terminated."

...

Sherlock inspected the bowl.

"So, Eurus... I don't remember much about our childhood let alone you. Why don't you shed some light?"

Eurus's eyes lost their sparkle a bit as she bit back a sad smile. "We used to play, Sherlock."

"What did we play?"

She chuckled softly. "You remember."

"Pirates."

He heard an applause and he tilted his head in reply.

"Well done. But we never played together. You were always playing with him. He's one of the reasons why you're like this. Why you can't conduct any emotional feelings. Like me,"

Sherlock placed the dog bowl down. "I remember, Eurus."

"Do you really?"

"We had a dog. I named him Redbeard. I adored him."

Eurus shook her head, knowing that he couldn't see her. "You adored Redbeard, all right. He was your best friend."

"One of the only two that I have in the world," Sherlock replied.

"Redbeard was the reason why you never played with me. How could he hold more value than me? Your sister."

Sherlock closed his eyes. "We were diff-"

"We were the same!" Eurus cut him off. "The same."

"Mycroft told me little about you."

Eurus sighed. "Did he tell you that he faked my death and told Mother and Father utter lies?"

Sherlock stayed nonchalant. "Mycroft likes keeping his secrets."

"Did he also tell you that Sherrinford long since quit the SS and has had me trapped in an asylum for these past decades?"

Sherlock remained unfazed. "Again, each brother is entitled to his own secrets."

"But they hurt me, Sherlock! You're the only one I could have trusted!" Eurus screeched. "But you hurt me too when you put that irrelevant before me!"

"Eurus... I am running out of time, I need this clue."

Eurus giggled. "Indeed you do."

Sherlock clenched his fist and inspected bowl once more.

"Redbeard was so handsome, wasn't he?" Eurus said nonchalantly.

Sherlock halted, turning his head to face the window. "What... did you mean by that?"

"That he was handsome. Annoying but handsome. Wouldn't have minded a bit of that when we grew up."

Sherlock's face contorted into shock. Redbeard... no, wasn't a dog... but, a little boy. Victor Trevor. My best friend. My first best friend.

"Mother always knew what child grew up to be such handsome little things."

"Wh-what did you do to him?"

Sherlock remembered wandering through a farm as a child, in front of a great big stone house, calling for Redbeard.

"He... died, Sherlock."

He closed his eyes as the painful memory emerged. They did say that once children experienced traumatic things, they tended to block them way out.

"I..." He gulped. "Was Yellowbeard and he was... Redbeard. You killed him..."

Eurus nodded. "So, who's John to you now? Redbeard's taken, darling."

Taken. It meant so many things. Taken by the Lord... Taken as a name... The list went on.

"Bearing in mind, it has to fit your little pirate theme. You were so immature."

"So. Were. You." Sherlock gritted out. "And he's Blackbeard."

Eurus gasped. "Seven minutes. Boy, those eight minutes flew by so quickly!"

Sherlock glared at the window. "The clue?"

"Blackbeard is inside the clue," Eurus replied, yawning. "You may proceed to the next room."

Sherlock tried the door but it wouldn't budge.

"Oops... How about I make this easier, hmm? I'm giving you twenty-three minutes back. That's me being kind, brother mine."

He sighed, leaning against the door. He wasn't sure whether it was out of relief or out of fed-up-ness.

"Your clue."

Eurus smiled. "What is my name, Sherlock? Who am I?"

"Eurus..." Sherlock said, trying the door. "Is that it? Is that the code?"

Eurus shook her head, resting her feet up on the small desk that she watched behind from.

"Try again." She said. "What is my name?"

"Eurus..." Sherlock's eyes widened. "Greek for the east wind is coming."

The door clicked open.

"You may proceed."

He didn't waste any time in leaving the room before she changed her mind but he stopped when he realised that he didn't know which door to open first.

"You have a choice," He heard on the tannoy. "The left for Dr Hooper. Or the right for Dr Watson. Who do you value the most?"

Mary's appearance suddenly stood beside him. He never felt so relieved for his subconscious.

"Who are you going to choose, Sherlock? I can't help you decide this. You need to let one go." Mary said gently, a sad look in her eyes. "The mother of your unborn child to carry on the Holmes legacy or my wonderful husband, your one and true best friend other than that poor little boy, Victor to remain the only constant in your life other than your family? The one who taught you what love is."

She was not helping. He valued them both. John was a father and Molly was a mother-to-be. They both had people depending on them.

"Tick-tock, Sherlock."

Sherlock started towards the left, making Mary gasp but he paused and turned to the right door.

"I'm sorry, Molly."

Sherlock made his way to the right door and whispered to the voice activator, trying every possible phrase he could think of containing the word 'Blackbeard' in it.

"You have fifteen minutes instead, Sherlock." Eurus smiled.

Sherlock glared at the camera, knowing that she was seeing. He continued to try new phrases, wasting more time. He almost hit his head at knowing the most obvious one.

He cleared his throat and spoke, "You are my Blackbeard, John Watson."

The door beeped and John looked up to see Sherlock.

"You did it," he said in disbelief. "Where's Molly?"

"I could only save one."

John frowned and exited the room. "What do you mean?"

"We have to leave, John."

"No! Do you know how much that woman has done for you? She let you use her and now you're abandoning her-"

A bullet shot past them and they turned to see a guard.

He took his helmet off and gave them a smile. "Anyone order a saving?"

"Sherrinford," Sherlock smirked.

"Follow me, gents."

John stood his ground. "We have to save Molly."

Sherlock groaned and turned back to the door on the left. He could see Molly anxiously sitting down on the floor, biting her nails.

"Eleven minutes," Sherlock whispered to himself.

Molly's clue was 'I love you' but he did not love her, did he? He knew she loved him, probably worshipped him but after what had happened between them, her hostility came through strongly.

"Sherlock," he heard Eurus whisper. "You have to make her say it."

Sherlock's breathed hitched as he forced himself to knock on the door.

"M-Molly? Hello."

"Sherlock?"

"B-Before I open this door... I need you to say something."

Molly stood up and walked over to the door, pulling her jacket's sleeves down. "What is it?"

"'I love you'."

Molly scoffed, shaking her head. "You have got to be kidding me. This isn't a joke, Sherlock. There is a bomb and there's a timer inside this and you want me to tell you that I love you so you can open the bloody door?"

She didn't understand. She had to do the work in order to open the door herself. He couldn't do anything.

"Please, Molly. I need you to say this, to mean it. For me."

"Bullshit, Sherlock. You know I would mean it but I can't say it. You don't love me so why should I humour you and get my heart broken in the process? You're a real piece of work, you know?"

Sherlock almost cried out in frustration. "Please, Molly. Look, I'll say it."

Molly's eyes darkened. "Don't you dare, Sherlock. You have to mean it."

He knew that he was getting nowhere with this so he turned to face John and Sherrinford. "Leave, I've got this."

They nodded and Sherrinford led the way out, back the way he came from.

Sherlock pressed his hand on the door and closed his eyes.

"I mean this when I say it."

"You don't," Molly cried. "Don't say it, don't bullshit me."

Sherlock took a deep breath. "Molly... I love you. You are the mother of my unborn child and that makes me love you even more than I do right now. You have to believe me."

He felt sick like he really wanted to throw up. He remembered loving Victor.

Molly shook her head. "I don't believe you but... I love you and I hate that-"

The door clicked open and Sherlock breathed out a sigh of relief, bringing her to his chest, tightly.

"I... I was standing in the way of my own saving..." She realised, mumbling against his chest.

"It's quite all right. Look, I need you to go okay? I'll be right behind you. John will be in front of you. There's an exit it's just straight ahead, turning into the left. I need you to continue down that path and do not stop until you've exited the building and stay back."

...

"Where's Sherlock and Dr Hooper?" Mycroft asked, walking up to John and Sherrinford who were starting to get people behind the perimeter of the building.

John turned to the middle Holmes brother to reply.

"Inside. The woman wouldn't cooperate."

Mycroft's eyes widened. "You don't understand, 'Ford."

John's interest peaked. "What?"

"Molly's pregnant. With Sherlock's child."

John gasped and Mary's presence stood beside him, excited.

"How wonderful!"

"How? When?" John asked.

Mycroft shook his head. "Now is not the time. We need to make sure that they leave this building. Alive. Anthea, the tablet."

Anthea handed her superior the tablet and told him about Sherlock's and Molly's positions.

"One is moving towards the exit."

"Molly," Mycroft nodded. "Sherlock?"

Anthea shook her head. "Still in there."

His heart dropped and he looked at the building which was to be in pieces very soon.

...

"Why did you make me say those words?" Sherlock asked, storming back into the room with the bowl and coffin.

Eurus giggled. "Six minutes, brother mine."

"Why?!" He roared, smashing up the coffin. "You knew! You forced me to s-say those words!"

Eurus rolled her eyes. "You sure do dramatise! Then again, you've always have been the more emotional one out of us four." She sighed, shaking her head. "But boy did that change after Vicky's death."

Sherlock smashed the bowl too for good measure. "You're demented."

"Says the guy who has not noticed that I had since left. Better yet, I was never here."

"W-what?"

Eurus laughed loudly, clapping her hands as she looked lovingly at her violin. "Visit me some time, huh? We can play together. Like old times."

"But Moriarty, Irene!"

Eurus picked up her violin. "Hologram. Irene... she just happened to be passing by. She's gone now." She started to play. "This is yours. Hear the tune? This is what I will continue to play as you die."

She then stopped talking and let the violin speak for her.

Sherlock stumbled out of the room, the familiar child's song ringing in his ears.

"Four minutes."

Sherlock leapt into action, standing up and running out of the room, following the same instructions that he had relayed to Molly minutes before.

He was surprised to see her waiting for him.

"Took your time," she breathed out, taking his arm as they continued down the hall.

"Why did you wait?"

Molly sighed, "As much as it hurts me to love you and hear you lie..., you are still going to share something with me."

They continued down the path which felt like forever.

As Molly's eyes narrowed to a sliver of daylight, she tugged on his arm harder and ran out just as the building exploded behind them.

They were flung into the air and the people outside ducked back, shielding their own bodies as everything exploded into pieces of metal, glass and wood.

Sherlock and Molly landed on the ground with a thud, their hearts beating loudly as their ears rang.

Molly's body stilled once she realised that she landed on her front, not back or side. The tears came as the pain slowly made its presence known.

Sherlock turned to face her, his hand reaching for her but she didn't take it. Giving up, he succumbed to the darkness.

...

Everything was moving. Annoyingly bumpy.

He groaned, lifting a head up to his head but not opening his eyes yet.

"Sherlock?"

"Mycroft..." He responded, finally opening his eyes. The light blinded him and he used his arm to shield his eyes.

Mycroft used his umbrella to steady his body in the bumpy ambulance ride. "You have suffered some minor burns. A horrible concussion. I can tell you more?"

"Molly..."

"I cannot disclose on her well-being just yet. I chose to ride with you."

Sherlock took a ragged breath. "You know that she's pregnant. Why didn't you prioritise her?"

"Because John made the decision for me."

"He knows?"

"Everyone does. I had to inform them of the severity we were dealing with. Children have lives that matter, you know?"

Sherlock wished he could open his eyes just to roll them. "I know. Rosie matters. This baby matters."

"Glad you agree. How about I check on her as soon as we get you medical attention?"

"Please," Sherlock begged. "If anything were to happen to her or the baby... I couldn't live with myself. All of this happened because of me."

Mycroft sighed, pinching the bridge of his nose. "Sherlock, all of this happened because of me. Not you so do not blame yourself. My lies nearly cost your life."

"Are you... being sentimental, brother mine?"

Mycroft shared his brother's smirk and opened his eyes. "I'm being... emotional, as you put it. Someone has to be strong in this time of need."

"What happens to her?"

"Sherrinford is dealing with that. Do not worry, my little brother. Everything will be back to normal."

Sherlock shook his head. Nothing was ever going to be the same. "What about Mother and Father?"

The elder brother winced. "I am working on that. Mother surely did not waste any time in berating my and 'Ford's actions. She is not a happy woman."

"I should believe that she is not. Do they know about Molly?"

"I thought that it would be best to speak to Molly before entrusting anyone else with the news. After all of this, she may not wish for you to be near the child."

Sherlock nodded. "I would expect nothing less and nothing more. I deserve everything that I have coming."

"You are a good actor, brother mine but, sometimes your persona slips. I know you really love that woman."

"I can't. Loving people gets them killed. Remember Victor Trevor?" Sherlock snapped. "You hid his death from me-"

"Now is not the time. I will explain all once you've recovered. Now sleep..."

Sherlock felt himself getting drowsy and slurred out, "What did you give me?"
