Cigarette Daydreams (A Teen!Lock, JohnLock Fanfiction)

Leaves fall delicately from trees. Birds chirp quietly in the distance. Laughing of babies out in the park.
All of these beautiful things weren't interrupted, but continued on as something else happened at the house at the end of the street, with the apple tree in the front yard.
This is the house of John H. Watson, who spends his days in his room with his music turned loud, trying to escape the sounds of beating flesh and cries of his mother.
His mother who is sending him away.
Worrying is John's specialty. So when John meets a new boy, the boy in question immediately has his heart.
Raven curls, beautiful deductions. Cigarette smoke, minty teeth and sharp bones. Adventure, danger, destruction. John is undeniably in love with this boy when he first laid his eyes on him.
But that isn't the problem.
People are dying around him. His pet. Someone who shook his hand. A boy they were chasing for a case. A close friend.
And he doesn't know how to feel anymore.
