((Oh, god, tell me about it. I'm going to go ahead and fast forward to the fluff nao. Besides, anything after Sherlock Holmes utters the words "bedroom is that way" are utterly superfluous, I think. XD))
So they don't actually end up helping Lestrade that night. In fact, any and all calls from said Detective Inspector are completely ignored by the both of them, John not even thinking could be important, could be about Moriarty, could be an emergency because the world has narrowed down to Sherlock and their (their, he notes with glee, not Sherlock's) bedroom and nothing else matters.
He wakes the next morning with his head pillowed on Sherlock's shoulder and his hand resting over his heart, Sherlock's arm around him, the two of them fitted together like puzzle pieces. He stays still for just a moment, eyes closed, enjoying the soft rise and fall of Sherlock's chest and the pleasant thrumming of his heartbeat. He feels so content that it's hard to believe the events of yesterday actually happened, and he takes a minute just to adjust to this new reality. When he's adequately prepared, he lets his eyes slowly flutter open and moves his head slightly to look up at Sherlock, and his breath catches in his throat.
Sherlock is asleep. Actually asleep. John is used to seeing Sherlock in constant action, a whirlwind of movement and words, never pausing, never resting. Most of the time he's still up long after John's gone to bed, and awake far before John comes down in the morning. And judging by the violin that sometimes wakes him in the middle of the night when he's having his worst nightmares, there's no telling if there's any sleeping done in between. Even when he finally crashes after a long, sleepless case, body too fatigued to continue, it's as often on the couch as in his own bed, and it's always accompanied by that slight frown, as if even in sleep he's annoyed at his body's failure to just keep going.
Not so now. His expression is utterly peaceful and relaxed, his lips even slightly quirked up as if he fell asleep mid-smile. His breathing is slow and deep, his face turned towards John, and all of the manic energy has drained out of him, replaced by a quiet relaxation. He's utterly, completely breathtaking, and John is struck once again by how very lucky he is to witness this. To be the cause of it. To have Sherlock. So he leans up very slowly, trying to disturb Sherlock as little as possible, and kisses him very gently awake. "Morning, love," he breathes, a blissful smile on his face. He could do this every morning of his life and never get tired of it.
