The Prompt for this was - Depression. (don't make it about Reichenbach Falls, though) All honesty I dislike this one. Sherlock is too OOC in my opinion.
Whenever Sherlock does feel a slight ounce of, what we humans call, depression, he will hide. John will always know where to find him.
John took the usual walk through Hyde Park before turning a corner to come to a collect of trees. Though it was misty and he could barely see, he knew where to look. It didn't take him long before he was amongst the trees and looking down at the curled up man on the floor. "Sherlock?"
No answer.
"Sherlock, look at me." The man slowly uncurled and looked up towards John. His eyes no longer glistening but dull. Not rimmed with red like you would usually expect. Just dull. John sighed as the right side of his mouth slightly turned up. "There we go."
Sitting down next to Sherlock, John never lost eye contact. Knowing in some way it helped his friend. "Why did you come?"
"Why do I always come, Sherlock?"
"I don't know." Sherlock sulked, reverting back into a ball. How John had first found out about his old town hiding place as a child was beyond him.
John shook his head and placed his hand gently on top of Sherlock's curls. His fingers entwining with the silky black strands. "It's the same reason every time, Sherlock." They sat there for a while, the mist thickened and the day turned into night. John never tore his eyes away from the, still conscious, curled up detective. Leaning down, he placed a soft kiss on Sherlock's head and kept his lips there so only Sherlock could hear his whisper, "because you are a big child sometimes and you need me."
