001: Captain
John bought Sherlock a pirate captain's outfit for his birthday - a joke. Sometimes Sherlock flops about in it in the flat alone - not a joke.
002: Servant
John always tips the waiters for both of them. Though he is furious when he steps outside to find Sherlock has not waited for him, never stops.
003: Inside
Sherlock hates the inside, whether its inside himself or inside his flat. The less things relate to him personally, the better. Outside, there's space to run away.
004: Outside
They have both always felt outside, different, but now their lives are full of inside jokes and inside glances.
005: Cold
Sherlock hates the cold ever since the front door of his house was slammed shut by his parents after his school report. On a winter's day.
006: Warm
A bath of a perfectly balanced temperature is John's necessary luxury; it is everything Afghanistan wasn't.
007: Book
When Sherlock mistreats a book, something inside John curls up. John loves books; Sherlock just needs them.
008: Drug
To ignore Sherlock's drug abuse would be immoral, to treat it would be against the doctor's code, to force him to get help from an outside source would impossible. John compromises by being there for Sherlock, quietly.
009: Dishes
Sherlock stops everything to watch John wash up, fascinated - he would throw the dishes into the wall. Or, if feeling polite, the bin. Or just not use plates. Or not eat.
010: Coat
Sherlock has been known to wash his coat in the sink. John doesn't point out the sink is for dishes, and the washing machine is right next to him. He just watches.
011: Cream
Sherlock notices that John suits cream clothes, drinks cream tea and has palms that turn cream in the cold.
012: Cane
John hangs his old cane next to Sherlock's skull; both are forgotten.
013: Cards
Snap! Sherlock tries to predict the next card whereas John relies on his physical speed. The game's a mess.
A/N: Thank you all for reading! 221 is not divisible by many things. Embarrassingly, I actually had to google 'what is 221 divisible by?'. Apparently a lot of people want to know the same thing. Anyway, 13 words per chapter in 17 chapter sounds good. Odd, Sherlockian numbers.
