A/N- Hello! I thought I'd attempt a bit of a John/Lestrade fic. I was listening to The Scripts album – Science and Faith and it gave me an idea. I put the songs in a different order than the album so I could use them for each individual chapter. 10 songs, 10 chapters. A song per chapter! I don't know if it will work as well as I think it might so any form of feedback is welcome! Enjoy! :)

Chapter 1 – 'Long Gone and Moved On'

Sherlock and John pulled up in the taxi to the crime scene at Lauriston Gardens. John, still confused on why he was there, hobbled after Sherlock who was already bounding ahead. He managed to catch up with him as a woman at the tape stopped him. Just as he caught up she was about to let him through but then looked towards him. Sherlock explained that John was with him and then she gave in and let him through.

After a brief encounter with Anderson, with a few deductions here and there, Sherlock and John made their way in and bumped into Lestrade.

'Ah Sherlock, your here. Who's this?' He said turning towards John.

John was about to answer for himself but Sherlock got there first. 'Dr John Watson, my new colleague and flat mate as I am sure you noticed when you came and asked for my assistance.'

Lestrade nodded his head slightly. 'Right, well. You boys will have to be quick. I'm breaking the rules just letting you in here Sherlock!' John smiled towards the silver haired man. Lestrade smiled before quickly turning towards the stairs.

They all headed upstairs and went into the room; the room where a woman dressed in pink, lay dead on the floor. John looked at the body before looking away again, then looked back again. Lestrade stared at the man before asking 'You ever seen a dead body before?'

'Plenty, I was in the army.' John answered.

'Oh, an army doctor. How come your back in London then?'

'I got shot.' John looked at him and then to the body.

Greg looked down biting his lip. 'Sorry, bit of personal question.'

John looked up at Lestrade trying to grab eye contact. When they did he said 'Not really, no need to be sorry.'

John didn't know what it was but he saw trust in the older man. Whether it was because he was a member of the Met or he was just a friendly guy he did not know.

'So you haven't known him long then?' Lestrade said nodding his head towards Sherlock who was trying to deduce the woman.

'We met yesterday.'

'And your already flat mates?' Lestrade said looking astonished.

John laughed shaking his head. 'I needed a flatmate, so did he. He seemed to know enough about me, so I googled him.'

Lestrade laughed. 'Good idea, least you knew roughly what to expect. Although good luck, looks like you'll have your hands full.'

John frowned slightly, still smiling not knowing what to do with that comment.

'If at any point you want to shut up for a moment Lestrade to let me think I would be more than grateful.' Sherlock said. Lestrade just rolled his eyes.

Sherlock stopped for a moment and looked up at Lestrade. 'It's a month today isn't it?' Sherlock said.

'What is?'

'Since your divorce was finalised.' Sherlock pointed out.

Lestrade sighed. 'Yes, it is. Thanks for pointing that out, I would never have known.'

'Sarcasm doesn't bode well with me Lestrade, you know that.' Sherlock said raising an eyebrow.

'I know, that's why I do it.' Sherlock turned around and started saying his findings.

John was still standing there, not looking at the body this time. No, this time he was looking towards the Detective Inspector. The man clearly kept himself well groomed. He looked a lot younger than what he probably is. John felt as if Sherlock was looking at him so he forced himself to look towards the body.

Lestrade had been doing the same thing but in a less obvious fashion. He'd known Sherlock for 5 years so had a better idea of making it difficult for Sherlock to infer. Difficult, not impossible.

'John, can you please identify how the victim was killed.' Sherlock said.

'I thought you said you knew?' John looked puzzled.

'Yes, but they will obviously want a medical professional to declare it.' John nodded and bent down towards the body.

John declared the cause of death and with knowing everything else Sherlock made a dash for it. He was left at the top of the stairs next to Lestrade.

'So, he's gone?' John asked Lestrade.

Lestrade nodded. 'Looks that way.' John looked confused. Greg took a breath in 'He always does it.'

'Right. Well I best be off then.' John stood up straighter and turned to walk back down the stairs. He turned back to Lestrade. 'So, I will probably see you soon?'

'Most definitely.' Lestrade smiled. John smiled back heading towards the stairs.

'Dr Watson?' John looked back, again. 'You might as well have my number, I mean, Sherlock, any problems with him just give us a text or ring.' He said to John handing him a bit of paper he scribbled his number on to.

'Thanks, will probably come in handy.' John smiled this time making it all the way down to the bottom.

Lestrade watched the ex Army Doctor, until he could no longer see him. He breathed in again. Something about John made him feel... happier? He was smiling to himself as Anderson came out.

'Sir, your needed.'

'Right, yeah coming!' Lestrade looked down the stairs once more, then went back to work.

'Sherlock? Where are you going?' Lestrade asked as he walked off after describing who the mystery gunman would be.

'I need to discuss the rent...' Sherlock said starting to wonder off again.

'I still have questions!'

'Not now, can't you see I'm in shock! Look, I have a blanket.' Lestrade raised his head then nodded.

'Right, we'll bring you in tomorrow for further questions.' Sherlock smiled and walked off, throwing the blanket away as he did so.

'I know it was you John.' Sherlock said when John caught up.

'Know it was me?' John said trying to look confused.

'Who shot the cabbie. I'm not stupid.'

John sighed 'Is there any point in arguing?' he said facing the way they were walking.

'No. Dinner?'

'Starving!' John replied.

'Chinese down the road from us, will pick some up and eat back at the flat.' Sherlock said, John following his lead.

It was late when they arrived back, Mrs Hudson had obviously gone to bed. So the two men walked quietly up towards the flat. John went into the kitchen and grabbed some plates. Both of them sat on the sofa seeing as the kitchen table was occupied with a number of different pieces of science equipment.

'So you like him then?' Sherlock asked breaking the silence as John returned with some plates. Ones that didn't look like they were about to shatter.

'Like who?'

'Lestrade.'

'He seems a very pleasant chap, yeah.' John nodded handing Sherlock a plate and taking a seat next to him.

Sherlock shook his head. 'Yes, but I mean you 'like him' like him.' John felt himself going crimson. 'I'm never wrong John.'

'Well, after your speech earlier I'm surprised you noticed.' John said trying to buy himself time before admitting it.

'Just because I consider myself married to my work it doesn't mean I don't notice it. Anyway it was obvious from how much you were staring.' John put his head down, staring at his food. He was pretty sure he was all red now.

'Are you going to admit it John?' Sherlock said smiling at him.

John looked up.'He is good looking yes, but I don't know him. Anyway you said he was divorced. Presumably a woman, so he would never be interested in me.'

'You like males and females John, as does Lestrade. Anyway he is interested in you. As much as he tried to hide it, I didn't fail to see it.' Sherlock was looking at John still, who was looking down towards his food again.

'Can we talk about something else?' John eventually said.

'Sure.' Sherlock said. They were silent for a moment, so John asked him where it all had started. Flat mate bonding and all that.

It was about 9am and John just finished his toast and tea and was about to to go off and collect the rest of the very few belongings he had from his old flat.

'I shall meet you back here later then. Lestrade has summoned me. Need to answer some questions.' Sherlock saw Johns eyes light up ever so slightly at the mention of Lestrade's name. He made a mental note to ask Lestrade when he got there. After all it was unlikely he would answer any of the questions. He has wormed his way out of them before.

John set off first back to his old flat. He was going to walk it there and get a taxi back instead of paying for two taxi's. That would be pushing it on his army pension. Soon after Sherlock grabbed a taxi and was on his way to Scotland Yard.

When he got there he walked straight past reception up to Lestrade's office. No one questioned him any more. He knocked and entered Lestrade's office without waiting for a response.

'Had to be you, who else just knocks and walks into my office.' Lestrade said. 'How are we today Sherlock?'

'Good thanks. Did you sleep all right? Miss John too much?' Sherlock said taking a seat opposite Lestrade.

'What?' Lestrade looked at Sherlock, frown on his face.

'Don't be dim Detective. You like John don't you?'

'If I do, it's none of your business.' He replied, not denying it.

'Your in luck, he likes you too.'

'Sherlock what are you on about? I asked you in for questioning.' Lestrade demanded.

'I will if you answer mine first.'

'Blackmail Sherlock? Really?' He said raising his eyebrows up at him.

'Yes, and you know it works. So do you like John?'

Lestrade sighed and looked down at the pen he was fiddling with. 'Fine. I do. He's hot. You happy now? Can you answer my questions?'

'If you ask him out just don't make it awkward okay? He will still be coming along as my assistant from now on.'

Lestrade sighed. 'Whatever. Can you answer my questions?'

Sherlock took his phone out of his pocket. 'Would you look at that. I'm needed sorry Lestrade must dash.' Sherlock said rising and walking towards the door.

'It didn't even make a noise. Sherlock, come back!' He shouted after him.

Just as Sherlock walked out the door he said, 'It's on silent.' and hurried along down the corridor.

Lestrade sat there one hand on his head. He got up and closed the door, Sherlock never bothers. As he sat back down his own phone went of twice. The first message was from Sherlock.

You were right. It didn't make a noise.

It's not on silent either.

-SH

He shook his head at it and deleted it. The next message was from an unknown number.

Any tips on how to handle Sherlock?

John Watson

This made Lestrade smile. He saved the number and re-read the text. He then replied.

Don't let him talk to people.

Don't let him call you an idiot all the time.

And don't ever feed him while on a case.

-GL

Comparing him to a Gremlin are we?

-JW

Well, he doesn't exactly act human.

-GL

Point taken.

-JW

Lestrade sat there grinning to himself, reading through the texts one more time. There was a knock at the door.

'Come in.'

'Did you get answers of Sherlock?' Sergeant Sally Donovan asked.

'No, as always.' He said, still smiling.

'Your in good mood sir.'

'Aren't I always?' He said laughing.

'Of course, but you won't stop smiling.' Donovan said. She smiled back, as if it was contagious.

'Better than frowning all the time.' Sally nodded and walked out shutting the door behind her.

'God help me. I've fallen for Dr John bloody Watson!' Lestrade mumbled to himself. Not once did that smile leave his face.
