Y/N's P.O.V.
You want to work with me?
Meet me at Westminster Street Station.
30 minutes.

As soon as I received the text, I knew it was Sherlock and I couldn't help but feel excited. I got ready to leave immediately, knowing that it would take me at least 25 minutes to get there. Traffic was awful in London, it would be much quicker if I walked, so that's exactly what I did.
"You came." A monotonous voice spoke from behind me as I made my way down into the underground station. I turned my head to see the two familiar men behind me.
"Evidently." I replied.
"You must be John Watson. Y/N L/N." I introduced, holding my hand out. He shook it, clearly confused.
"Sherlock? You invited someone else along?" John asked as we walked.
"Yes, John. Y/N is my new flatmate." Sherlock explained, John looking at me in shock.
"I assume this is important?" I asked.
"I don't know, do you consider stopping a terrorist network working in the London Underground important?" Sherlock asked me.
"I don't have anything better to do." I shrugged and Sherlock smirked a little at my answer, whereas John just looked shocked.
"So, underground terrorist network. That's what Mycroft was talking about, right?"
"You know Mycroft?" John asked me, but Sherlock and I both ignored him as the curly haired man caught me up with what he knew about the terrorists.
"So it's a bomb, then? The tube carriage is carrying a bomb?"
"Must be." Sherlock sighed and John pulled his phone out of his pocket.
"What are you doing?"
"I'm calling the police." John muttered.
"What? No!" Sherlock protested.
"Sherlock, this isn't a game, they need to evacuate Parliament." John looked at his friend.
"Evacuating parliament is a terrible idea." I began to explain.
"If the terrorists realise something is up, they won't wait to set the bomb off. With the police involved, more people will get hurt."
"Besides, they'll just get in the way. They always do." Sherlock muttered.
"This is cleaner. More efficient." He discreetly broke the lock on a door that we definitely shouldn't be going through.
"And illegal?" John asked.
"A bit." Sherlock shrugged, opening the door and holding it open as we asked though. He closed it behind us and we made our way through the dark tunnel. The two of them seemed to come prepared with torches, whereas I just used my phone torch.
"So how did you meet Sherlock and Mycroft?" John asked as Sherlock walked ahead.
"I've known Mycroft Holmes for a long time and for the past 2 years, I've been saving his little brother's arse." I replied.
"You have not." Sherlock spoke up and I nodded my head mouthing the words 'I have'.
"Oh, so another person knew you were alive, but not me?" John asked him.
"Don't take it personally, he didn't know I was there until Mycroft showed up to bring him back. And I honestly didn't know he was alive until I found him attempting to take down the same part of Moriarty's network as me." I gave John a small smile, before we reached the station that was never officially opened.
"I don't understand." Sherlock spoke, looking both ways.
"Well that's a first." John sighed and I smirked a little.
"There's nowhere else it could be." Sherlock put his fingers against his temples as he closed his eyes and tried to think.
"Oh!"
"What?" John asked as Sherlock ran towards the tracks, jumping down.
"Hang on, Sherlock?"
"What?" The taller man looked at his friend as I climbed down onto the tracks.
"Isn't that... live?" John asked carefully.
"Yeah, probably." I nodded.
"It's perfectly safe as long as we don't touch the rails." Sherlock continued walking and I did the same as John followed, muttering to himself.
"Look at that." John said, shining his torch towards the abandoned carriage.
"John..." Sherlock shined his torch up and we all looked to see a whole bunch of explosives leading up through another tunnel.
"Demolition charges." I sighed, before we continued onto the carriage. I opened the door carefully, the two men following me inside as we all looked around, looking for any sign of a bomb.
"It's empty. There's nothing." John sighed, but out of the corner of my eye I saw something.
"Don't be so sure." They both turned to look at me and I lifted the seat cushion up, revealing part of, what I guessed was, a very big bomb.
"This is the bomb." Sherlock whispered, removing the next seat cushion.
"What?" John asked, clearly confused.
"It's not carrying explosives, the whole compartment is the bomb." Sherlock muttered as we began removing the seat cushions. I carefully touched one of the wires, shaking my head as Sherlock removed a piece of the flooring, revealing the centre of it all. John took shaky breaths as Sherlock looked at me, as if asking what to do now.
"We need bomb disposal." John murmured.
"There may not be time for that now." I sighed, running a hand through my hair.
"So what do we do?" John looked between us and the bomb.
"I have no idea." Sherlock admitted.
"Well, think of something." John shot back.
"Why do you think I know what to do?" Sherlock almost seemed offended and I rolled my eyes.
"Because you're Sherlock Holmes, you're as clever as it gets." John glared at him slightly.
"It doesn't mean I know how to diffuse a giant bomb. What about you?" Sherlock looked at him and they started to bicker. I moved back to one of the bombs that was hidden away under the chairs, looking at it carefully.
"Y/N? Do you know how to diffuse a bomb?"
"I'll admit that I'm smart, not as smart as you, but I'm smart. I could maybe diffuse the detonator charges out there. Maybe. But I don't have the tools or the time." I shook my head and Sherlock sighed, seconds before the lights flickered on and the bomb became active.
