JOHN: Hello?
SHERLOCK: John.
JOHN: Hey, Sherlock, you okay?
SHERLOCK: Turn around and walk back the way you came now.
JOHN: No, I'm coming in.
SHERLOCK (frantically): Just do as I ask. Please.
JOHN (turning back and looking around bewildered): Where? (Sherlock pauses for a moment while John walks back along the road, then speaks urgently.)
SHERLOCK: Stop there.
JOHN (stopping): Sherlock?
SHERLOCK: Okay, look up. I'm on the rooftop. (John turns and looks up, his face filling with horror.)
JOHN: Oh God.
SHERLOCK: I … I … I can't come down, so we'll … we'll just have to do it like this.
JOHN (anxiously): What's going on?
SHERLOCK: An apology. It's all true.
JOHN: Wh-what?
SHERLOCK: Everything they said about me. I invented Moriarty. (He looks around briefly at his enemy's grinning body lying behind him. On the ground, John stares up at his friend in disbelief.)
JOHN: Why are you saying this? (Sherlock turns back to look down at him. His voice breaks.)
SHERLOCK: I'm a fake.
JOHN: Sherlock …
SHERLOCK (his voice becoming tearful): The newspapers were right all along. I want you to tell Lestrade; I want you to tell Mrs Hudson, and Molly … in fact, tell anyone who will listen to you…(Sherlock knows he's lying, then realizes these are his last moments with John) that I created Moriarty for my own purposes.
JOHN: Okay, shut up, Sherlock, shut up. The first time we met … the first time we met, you knew all about my sister, right?
SHERLOCK: Nobody could be that clever.
JOHN: You could. (Sherlock laughs and gazes down at his friend, a tear dripping from his chin. Johns reactions break his heart).
SHERLOCK: I researched you. Before we met I discovered everything that I could to impress you. (He sniffs quietly.) It's a trick. Just a magic trick. (John has his eyes closed and is shaking his head repeatedly.)
JOHN: No. All right, stop it now. (He starts to walk towards the hospital entrance.)
SHERLOCK (urgently): No, stay exactly where you are. Don't move. (John stops and backs up, holding up his hand towards Sherlock.)
JOHN: All right. (Breathing rapidly, Sherlock has his own hand stretched out towards his friend.)
SHERLOCK: Keep your eyes fixed on me. (His voice becomes frantic.) Please, will you do this for me?
JOHN: Do what?
SHERLOCK: This phone call – it's, er … it's my note. It's what people do, don't they – leave a note? JOHN: a note?
Now, Sherlock sees that this is his last moment to say something to John. He pauses, eyes tearful, then finally speaks:
SHERLOCK: "So anyway I'm leaving… I thought you'd like to know… Your faithful come-what-may, But clearly I can't stay. We'd both go mad that way. So here I go… And anyway I'm leaving, I guess that you can see. I'll try this on my own. A life I've never known. I'll face the dread alone. But You'll be free…
(A tear falls from Sherlock's cheek, he breathes deeply) With you always beside me, To catch me when I fall, I'd never get to know the feel Of solid ground at all. With you always believing That we can still come through, It makes me feel the fool To know that it's not true.
(Sherlock laughs) What doctors call dysfunction, We tried to call romance, And true it's quite a trick To tell the dancers from the dance But rather than let chance take me I'll take a chance.
(Sherlock bites his lip, closing his eyes.) I'll take a chance on leaving, It's that or stay and die. I loved you once and though You love me still I know It's time for me to fly…
(Sherlock realizes what he's just said, but smiles, looking down at John) I loved you once and though I love you still I know… It's time for me to go. And so…goodbye."
