The first time they arrive on a crime scene after consummating their relationship, Sherlock isn't entirely sure how to act. Does John want him to stake a public claim? Is he the type who enjoys public displays of affection? Why is this so infuriatingly confusing? As they walk under the tape he places a hand protectively on the small of John's back, but hesitantly pulls it away, shoving his hands into the pockets of his coat.
However, when it's John who notices the abnormal and unexpected bruising around the victim's torso, John who finds the clue that makes the case, Sherlock can't resist grabbing him and kissing him fiercely for all the Yarders to see.
"So, you and John, huh?"
Sherlock glares at Lestrade, managing to look down his nose despite the fact that he's squatting on the ground next to the corpse.
"What are you implying?"
"Well, that kiss was quite something. You guys finally realised what the rest of us figured out months ago?"
"Why do I need to announce it? John completes me. He is, to make a ridiculously heliocentric metaphor, the sun around which I revolve. I cannot begin to explain the depths of the connection between us. However, I suppose if it will make your sadly pedestrian little department happy, yes, he is now my boyfriend."
