So, I’m going to through my two-cents in for a Sherlock finale theory.
Here’s the latest hint we’ve gotten from Moffat, saying that:
There are two things that I find Sherlock did that were quite out of character.
1. He doesn’t talk for over two minutes
Sherlock usually never stops speaking. He talks a mile a minute even if no one is in the room. Yet, when he sees “Richard Brook” in the reporter’s apartment, he doesn’t talking for over two minutes. There’s no witty comeback. He doesn’t immediately say that he knows it even though, on the roof, he “of course” knew the origin.
This is a clue that Sherlock is on the game. When he first sees Moriarty as Brooks, his expression is of surprise:
but as the conversation goes on and we find out Richard’s name, he seems amused:
it isn’t until the end that he plays into Moriarty’s little game and has a very uncharacteristic emotional reaction to end their little game.
This makes me believe that he’s in on the little game that Moriarty’s playing and is encouraging the next step. He doesn’t shut it down when he easily could. He let’s the story play out and then acts crazy for no reason and never once defends himself.
Which makes me think that he’s planning the whole thing behind the scenes. He makes the story happen, since he’s the one that picks the hospital AND the rooftop.
and he knows that he has to die to end the story WAY before the morning building fall. He had plenty of time to make arrangements:
2. He plays dumb.
Sherlock would never intentionally look stupid. Never. But he does it over and over again. He doesn’t call Moriarty on the Richard Brook thing on the spot.
He played dumb with the Richard Brook situation, not immediately saying that the Reichenbach=Richard Brook thing was obvious and the whole thing was ridiculous.
Then, there’s the binary/computer code conversation. After Moriarty is released from prison, he goes to Sherlock’s apartment. Sherlock greets him with this song;
This song is called “Sonata No.1 for Solo Violin” by Bach. It is part of a set of six works written by Bach.
The Sonata No. 1 and the Partita No. 1 are closely connected…coming right after each other in the set of works:
So…how likely is it that Sherlock wouldn’t recognize the fingering for the violin part of the Partita No. 1?
But he willingly tells Moriarty that the tapping is a key code that he knows isn’t right. He’s not stupid…he knows a few piece of binary code isn’t going to do anything.But, he says it to make Moriarty think he has the upper hand.
Then, he makes Moriarty think he’s solved the key to calling off the assassins. He says that he can force Moriarty to tell them to go away and then does something very strange. He gives away his whole plan (instead of just doing it) and then brags about it. Sherlock would never do that…it makes him look silly:
He makes himself look dumb so he can let the story play out.
Now, I don’t know why he’s doing this but it’s definitely out of character. He’s not defending himself. He probably told Mycroft to tell Moriarty the stuff about himself to lead Moriarty on. He looks silly on purpose and plays everyone like a puppet.
To what point…I have no idea.
But, that’s what I’ve got! Do with it what you will :)
