I'm just going to let you read this for yourselves, Enjoy!
"Regan, He's dead. He was pronounced dead, no pulse" He says sympathetically.
"The only reason I'm telling you this is because I know I can trust you" She stands, "Did you see his body being lowered into the ground? Because I sure didn't. You can't truly be sure until you check for yourself" she says slyly. She then shows herself out.
Regan arrives home that night to Sherlock bustling about, shrugging on his coat and scarf, and shoving Regan's gun in his pocket, "I've done it, I've found him!"
"What? Sebastian?" She is startled.
He rolls his eyes, "Of course, Sebastian Moran, the final gunman".
"You're going to kill him now?"
"Yes, I'll be back soon" he opens the window.
She closes in on him, "Let me come. It could be a lot more dangerous than you think".
"No. As you said, it could be dangerous, I don't want you to get hurt. I'll be back soon" he winks and climbs out the window.
Sherlock creeps through the dark building, as he climbs the stairs he comes across a windowed room overlooking the building next to it, unlike the one he's in, it is well furnished. He goes to the open window and looks across through to the other building's window.
"Sherlock, I've been expecting you" comes the harsh voice behind him.
Sherlock raises his head noticing the gun pointed at him, with a straight face, "Well" he says as he draws his gun hurriedly.
Sebastian moves closer towards him, the windows now between them. "Stupid girl, Regan, stupid enough to follow you here".
Sherlock looks around and then out the window to the other building where she is searching franticly. "Don't even try to yell" he moves his gun so that it is now pointed at Regan through the windows, "Do and she dies. Shoot me and she dies. Move and she dies".
He stands there as still as a statue, he then follows Sebastian's aim at Regan and pulls the trigger, Regan is pegged in the left side of her chest and is taken to the ground. Sherlock then fires another shot at Sebastian, who was still shocked at Sherlock's action, and hits him in the heart.
Sherlock stands there for a moment, taking in everything that just occurred, he then rushes downstairs and to the next building over. He finds Regan a short moment later on the floor bleeding. He rushes to her side.
She coughs up blood, "You shot me".
"Yes, I did. If I didn't you and I would surely be dead" he consoles her.
"I'm dying" she whispers.
"No, I'm a great shot, an inch to the right and you would be" he grins.
She spits up more blood, "Give me the gun. I called an ambulance, you need to go and you were never here" she repeats, "Give me the gun".
He does as she says and hands it to her. He's kneeled at her side, "You'll be okay".
"I know, now go, go to my flat and wait for me there" she removes his hand from her forearm.
Sherlock stands and turns to leave, twirling his coat like batman in the process, and then vanishes.
A minute or two later an ambulance and Scotland Yard have arrived. The EMT's are putting her on a stretcher and a police officer comes to talk to her.
"Detective Inspector, there's no one over there, nothing" the young man says.
"What?!" she starts panicking, "Officer, send a car to 221B Baker Street for Dr. John Watson, immediately, tell him it's life or death" the officer nods and then starts to leave, "Wait!" she continues, "Send him to the hospital to meet me".
The officer nods for the last time and runs off.
John knocks on the hospital room door, "Regan?!"
"John! Come in!" Regan invites.
He strides to the door and takes a seat in the chair next to her bed, "Life or death? Are you the one dying?" he asks concerned.
"No. You are" she says as the nurse enters the room.
"Sorry but Ms. McKeller needs her sleep" the nurse tells John.
"Alright, just a minute more" Regan suggests. "John, go to my flat. There's a key under the mat. I can't explain, you'll be safe there".
"You have to leave now" the nurse pushes.
John gets up and walks out of her room.
Sherlock is sitting on the couch, he is worried. He hears the front door open and close, "You're back!" he yells.
John walks into the living room with a perplexed look on his face.
Sherlock stands at the sight of John.
John steps closer to Sherlock, he takes his last step and they are now only a foot apart.
"John-" Sherlock starts but is interrupted by John's hard fist meeting his jaw.
