John walked quietly down the stairs and into Sherlock’s room, the light was on and he saw Sherlock waiting, his eyes were bloodshot as if he’d been crying and he looked nervous. “Hey.” John spoke walking up to the bed.

“You don’t mind do you?” Sherlock asked looking slightly frightened.

Thank you, anon!

John is a mess. Sherlock can't fix him, but he tries. That's good enough, John thinks.

“You’re exhausted,” John said, his voice soft and compassionate. Sherlock nodded. “But you’re not sleepy,” he continued, noticing the tell-tale paradoxical signs of physical tiredness and mental alertness. These twin traits were the foundation of Sherlock Holmes.

Nightmares by trajektoria (T, pillow fight, not really sleeping)

John is not the only one who is tormented by nightmares. Even the great Sherlock Holmes needs support from time to time. And there's no better place to look for comfort than a bed. A bed shared with someone, preferably.

"Sleep," Sherlock tells him, sitting up straight and returning his eyes to the news, a small smile hovering on his face.

The Quiet Moments by belovedmuerto (T, cuddling)

Cuddling. Lots of it.

It started with the little things. A small touch, brushing up against him, Sherlock sitting closer when he was watching something or reading something. When they were both home Sherlock being in the same room, moving closer and closer until they were touching in some way, whether it would be their legs brushing against each other, or maybe their arms. A head suddenly resting on his shoulder. But it had gotten well... worse wasn't really the word for it. But it did increase. 

Bit by bit, Sherlock just didn't seem to ever want to be apart from him.  Offering to even go to the store with him. It was strange, even for Sherlock.  But John went with it of course.  He had to admit, having Sherlock Holmes come up to you and just curl into your side, who wouldn't want that? 

He would wrap his legs around him if he needed his hands, but if he didn't he would cling to him in anyway he could. One of the times he was worried his chair was going to fall because he had his legs on his shoulders and sitting on top of the chair. 

The behavior just kept happening, over and over again. Sherlock clinging to John until John soothed him enough that the overwhelmed detective fell fast asleep. 

He had been doing that as well- sleeping more often. But only when John was near. Something mumbled about nightmares once, but it was never mentioned again. As for the behavior, the cuddling part...

Honestly he had no idea where it came from. Sherlock just didn't want him to go, at least not go anywhere alone. Maybe it was because work kept taking him away? Or maybe it was because next month he was going to be gone, going back to the military so that he could talk to the new medical doctor recruits as a Captain. 

He had no idea Sherlock was worried about him. That while he was thrilled to see him in uniform he was worried about him getting shot again. Or maybe he was more afraid he would realize that being in wars was more exciting than Baker Street.... 

And leave him that way.
