I wrote this one on a bit of a whim, the writing style seems a bit unusual to me but I hope you guys like it, enjoy!
"So how did you do it?"
John looked up at Sherlock, the tall man in the good coat walking alongside him. That long eventful day was finally over. Sebastian Moran was in handcuffs, Sherlock's name was cleared, and the world knew that Moriarty was real.
Somewhere during the assassin's arrest Sherlock had started walking, and it was no surprise that John followed. They walked in silence through the nighttime mist, John taking extra strides to keep up with the taller man and Sherlock slowing to accommodate the limping man's pace.
"Do what?" Sherlock asked, his eyes searching the night.
"Survive, you sod. How did you survive?" John meant this question in two ways and Sherlock knew it, so he thought of his two answers carefully before replying.
"Well the trick on the roof was actually quite simple, but I don't think I'll tell you about it just yet. It's better to wonder." He smirked.
"You're just saying that because it sounds cooler than what actually happened." John accused, chuckling at his friend's dramatic tone.
"Maybe." Sherlock admitted. "As for surviving after my fall, that was a bit more difficult."
"Did you go back to using?" John asked with a dry mouth and dread in his stomach. Sherlock answered that question immediately.
"A few times. I'm clean now."
"Oh."
They walked down a few more streets, not really noticing where they were going. For a moment John worried that this was it, that Sherlock had come back from the dead to save him and now he was walking off to melt into the darkness and leave him alone again. That idea scared him so he grabbed Sherlock's hand. The detective didn't seem surprised by this, just gave John's hand a gentle squeeze in return.
"I lived off Mycroft's charity for awhile. When I wanted him to stop tracing me I stopped. Joined my own homeless network for a year." He continued.
"I can't imagine you homeless you're too..."
"Clever?"
"Clean."
Sherlock chuckled, brushing lint off the sleeve of his doubtless expensive trench coat. He'd left that coat with John the whole time, and first thing he did after revealing himself to John was to grab the coat and swing it over his thin form. He'd looked too thin without it, like a skeleton. Not threatening or impressive at all. Putting the coat on had been a huge improvement.
"Did you eat well enough? Sleep?" John pressed.
"Always the doctor, John." Sherlock sighed. "No, not most of the time."
"That has to change."
"Doesn't it always?"
They had come to a park by this point, and John felt himself struck with the sudden childish urge to sit down on the swings. For a second he pictured what Sherlock must have looked like as a kid and couldn't help but laugh. He was probably the one child sitting on the bench with a mold sample and a chemistry book while the other kids ran around pushing each other and playing football.
Sherlock sat on the swing next to his, giving him a curious smile.
"So...will you move back in to 221B?" He asked tentatively, kicking at the ground with his feet. He looked ridiculous with those long legs on a children's swing.
"I don't know." John stared at the sky. "Should I? Aren't we getting a little too old for this?"
"John! I'm appalled!" Sherlock smirked. "I suppose you plan on getting married and leaving me to solve crimes on my own then?"
"That was the plan..." John watched Sherlock's smirk melt away. "...now I think plans have changed."
"Have they?" John was having too much fun watching Sherlock go from frowning to hopeful all at once. He really was so easy to figure out sometimes.
"You'll have to make a few changes yourself." John insisted.
"Like what?"
"No more smoking. No more skipping meals. No more running into my room in the middle of the night when you've made a discovery that you think I need to hear about." John gave a stern face.
"You'll be the death of me!" Sherlock exclaimed dramatically. John's face grew dismayed and Sherlock hurriedly looked at his feet.
"Too soon." They both agreed.
"So, do you agree to my terms?" John stood, reaching out a hand in order to shake on it.
"We'll see." Sherlock shrugged, pulling himself up with the proffered hand. He held onto John's hand, pressing a quick kiss against his knuckles before they walked off towards 221B together.
