"Sherlock."
"John? Where are you?"
"I'm here, Sherlock. I've been here for a while."
"Well, then, where-"
"Outside, Sherlock. You'll see me."
Minutes later, John saw Sherlock standing below, searching the crowd. "Up, Sherlock. Look up."
Sherlock's gaze instantly found his friend. "John, what the-"
"Sherlock, listen to me. It's time for me to go."
"What do mean, John?"
"I mean that you no longer need my help."
"Well, of course I still need your help; why would you thing of leaving?"
John struggled to keep his voice steady. "I've completed my soldier's duty. I'm being release."
"Released? Released from what?"
A deep shuddering breath. "Goodbye, Sherlock."
John saluted, then jumped off the roof.
The last thing John heard was Sherlock screaming his name, almost like a sob.
