How did it come to this? Faking smiles and awkward goodbyes? No, he and John were never supposed to be like this. But they were. It was their new chapter, after all. Minor spoilers for 3x03 - episode tag for the ending, but without major spoilers.
"I'm your best... friend?" Sign of Three character study for the corresponding part in the episode.
Sherlock's YouTubing serviettes. Sign of Three character study.
Sherlock's having a little trouble getting ahold of himself after Magnussen visits him in the hospital. His panic is muted, but it's there, buried beneath the hospital-grade drugs he's hooked up to. Thankfully, John's presence is always better than the sedatives, anyway. [Set after the HLV deleted scene, whump, h/c, rated T because of the general tone of the deleted scene.]
Sherlock. Janine. The bathtub scene. Spoilers for 3x03. Rated T for allusions to adult situations, but nothing too racy.
The Personal Blog of Dr John H Watson: Should I be worried? My best friend has taken my wife out on a date. A real date. At a restaurant. With a reservation. I've literally no part in this decision, but... at least it's for a case. It is for a case, after all. It sure better be a case, or, so help me, Sherlock...
If Sherlock and John were a couple, then Sherlock, John, and Mary must be a trio. Johnlockary (I don't know what it's called, so I'm calling it that! :D) domestic fluff.
"Brother? Other brother? There's more besides you and Mycroft?"
Me? A best man? ! Set during The Sign of Three but no spoilers that people probably don't already know.
There's one person who can put Sherlock Holmes in his place... and that person is his mother. Fluffy family!lock, featuring Mum, Dad, Sherlock, and Mycroft... and John to bear witness, of course.
He had told Jim to not mistake him for an angel. Funny that, as it turned out, he was. AU Wing!lock... sort of.
Really, he didn't know that tuna casserole could be toxic. Sick!fic.
His eyes turned to one of the pillows on the bed, his eyes flashed golden-brown, and the pillow shot the few feet from the bed to hit Arthur on the back of his blonde head. [Set in Series One/early in Two (because I've only seen one series so far).]
Sherlock cares for Mycroft. Of course he does. The "I hate you! I hate you, TOO!" is just what they do. But when Mycroft gets ill and ends up in hospital, Sherlock is, as Mycroft would say, incredibly transparent. Sherlock/Mummy fluff. John's there, too.
It was weird. But Sherlock was having a panic attack. Re-write of the Hounds of the Baskerville scene. Doctor!John.
After Mary dies, Sherlock is left to help John pick up the pieces. Which would be considerably easier if... he wasn't going to pieces himself. T for angst and topic.
Mycroft's sick. Really sick. While that isn't going to make Sherlock hit the floor and spew declarations of love for his brother, that isn't to say he isn't going to be there for him. Rated T for the topic, mild angst/trigger warning.
"... I'm detoxing." John didn't know if he was being thick or if Sherlock was trying to admit something to him. "From what?" he asked. "The morphine, John, obviously!" Sherlock swept to his feet, burgundy dressing gown spinning out around him. [Set in HLV, between Sherlock leaving hospital and Christmas. Rated M for material and occasional swearing. Trigger warnings as such.]
Sherlock's visited by an past acquaintance, a present one, and one from the future. Maybe it wouldn't be so strange... if all those acquaintances weren't already dead. [Sherlock/A Christmas Carol fandom fusion. No knowledge required of the book! Set immediately post S3, rated T for mostly later chapters.]
In which Sherlock is both John AND Mary's Valentine. [Platonic Johnlockary Valentine's fluff.]
