Holmes: Hello Moriarty.
Moriarty: Sherlock...
Holmes: You are exceedingly hard to find you know.
Moriarty: Not to difficult for you of course.
Holmes: Of course. It's a simple matter anyhow. So, how much longer until you give up? I'll beat you anyway.
Moriarty: Your exceeding arrogance amuses me to no avail, Holmes.
Holmes: While yours just simply annoys me, Professor.
Moriarty: I see your wit has yet to dull... No matter. It will all be over soon.
Holmes: Oh I think my wit has plenty to do with the task at hand. But you are correct, it will all be over soon.
Moriarty: Over in a sense of ending. The end being yours. Yours being death.
Holmes: It amazes me how you can be so ignorant, yet avoid capture for so long. Anyway, no matter how this will end, it with ultimately lead to your downfall.
Moriarty: Speaks to your own prowess doesn't it Holmes? Such blind arrogance. You no not of what you speak.
Holmes: Oh, I know exactly about what I speak, and I mean every word.
Moriarty: I suppose that must be true. A student of primary school could deduce your simple speech.
Holmes: I wouldn't know, I have deleted all that useless primary school information.
Moriarty: Pity, for that is all you had.
Holmes: Oh, your wit almost matches mine Professor. Almost sad such a comical personality had to come in contact with such a wicked mind.
Moriarty: Almost.
Holmes: Yes, almost. It's of little consequence now, the end is very near.
Moriarty: I had almost forgot how often you did love to repeat yourself. "If you repeat something enough it eventually becomes fact" eh, Sherlock?
Holmes: Well, you certainly have a fantastic memory.
Moriarty A man must.
Holmes: Indeed.
Moriarty: Where IS that infernal lapdog of yours?
Holmes: I assume you mean Watson, he is out at the moment.
Moriarty: Ah yes, Watson.
Holmes: It is of no concern to you anyhow.
Moriarty: I believe it is entirely my concern, dear Sherlock.
Holmes: How so?
Moriarty: Do you happen to know where he is? At this very moment?
Holmes: You haven't.
Moriarty: Haven't I?
Holmes: You do anything and you won't live to see the light of day.
Moriarty: Ah, the mutt's brutish nature is finally revealed! I can't say I'm shocked, old boy. And what will you do? Kill me?
Holmes: Well, that would just be too easy wouldn't it.
Moriarty: Wouldn't it. That's exactly what I thought.
Holmes: But you can only guess what I would do if you so much as lay a hand on him.
Moriarty: Perhaps, I am admittedly poor at predicting the thoughts of a child. Their thoughts as scattered as they are. Death would be to easy wouldn't it? You agree?
Holmes: I agree, you're not afraid of death.
Moriarty: Let us hope neither is your friend, Watson. For his sake.
Holmes: You won't kill him, not yet. You forget I know how your mind works Professor. No, you won't kill him.
Moriarty: "Too easy" to quote you.
Holmes: You do like quoting me don't you?
Moriarty: Only because it amuses me so. You're futility.
Holmes: Just let Watson go, he has nothing to do with this.
Moriarty: Doesn't he? scream of pain in the distance
Holmes: This doesn't involve him! Just let him go!
Moriarty: patience old boy patience. It will all be over soon. Scream intensifies
Holmes: You will be your own downfall and you know this. Why must you bring those who have done nothing to you into it?
Moriarty: My own downfall? Ha.
Holmes: Yes, you have created something that in the end will collapse around you.
Moriarty: ... What do you mean?
Holmes: Once I find your loose thread I can pull it until your entire operation unravels.
Moriarty: Unfortunately for you, I have no such threads.
Holmes: You have made mistakes, you are human after all.
Moriarty: I have surpassed such generalizations.
Holmes: You have not. You are, in fact, a monster but still human and all humans make mistakes.
Moriarty: You fear what you do not understand Sherlock.
Holmes: So do you.
Moriarty: There is little I do not understand.
Holmes: But the little you do not, you fear. I know you fear me Professor, or wouldn't have bothered talking Watson.
Moriarty: ...
Holmes: You know I am correct. So give up Professor, while you still have a chance of living.
Moriarty: I.. I... NO! I will not give in to your taunts!
Holmes: Ha, taunts. These are not taunts Professor, this is real life. It's how this little game of ours will end.
Moriarty: No... NO! I will not lose...
Holmes: You have already lost!
Moriarty: SILENCE
Holmes: NO! You must be silent now. It's over Professor, and you have been defeated.
Moriarty: No...No..
Holmes: Yes.
Moriarty: No!
Holmes: Now you are the one repeating yourself.
Moriarty: ...
Holmes: You have nothing, you are finished.
Moriarty: You may have bested me this time. But never again.
Holmes: This is the last time Professor.
Moriarty: Once again, proving your foolishness...
A/N: As for the physical actions, I'll let your imagination fill it in.
