Well, Sherlock knows that John's life is in danger as long as he himself is alive. He must make John believe he is dead. If John knew that Sherlock's still alive he might betray his knowledge to others because he's a very honest person and a very bad liar (e.g. at the end of SiB). 

In the end it doesn't matter if John believes him to be a fraud - he must believe him to be dead.

BTW, I see you're new here. It would be nice if you could introduce yourself in our introduction's thread. And if you look around you'll see that many of your questions may have been discussed and answered already. 

Thanks Susi, I introdced myself now. And I did read some of the post before I registered but not all of them yet.

To your theory: I don't find satisfying because I think if, as you said, in the end it doesn't matter if John believes him to be a fraud, then he wouldn't have made such an effort. Also I don't think he would have told anyone who shouldn't know but thank you for sharing your opinion with me

I think he had to give him some reason for committing suicide. Sherlock couldn't tell John that there was a threat to kill John, Mrs Hudson, and Lestrade. That would have been far too dangerous. 

Maybe he didn't expect John to arrive just the moment he was going to jump. And we don't know which preparations were made while he was standing on the edge. So he had to talk to John and play for time until everything was ready. And the logic conclusion was to give him a reason for his suicide and he came up with this story. 

Thank you, Tobe, canon is always a fine proof.

Well if it's form Canon than that'll probably be the reason the producers had in mind. But it's cruel. Do you think that in the series it'll be three year between season 2 and 3?

Oh please not! They can not be separated for longer than they have lived together!

18 months at the very most. This is the modern, digital world. With Mycrofts connections, it shouldn't take very long to dismantel the Moriarty web - or at least a good part of it.

I guess (and hope) that it'll be even less. As I already said in the "When does he come back?"-topic I don't think that the gunmen are still a thread. And I don't think Moriary has a big network anyway, but that's just a feeling, he seemed to me like someone working alone hireing people only when he needed them.

I think there still exists a serious threat to Queen and Country. Just think of the "flight of the dead" matter. Moriarty could be head of a terror cell of some kind.

I agree - he's definitely got a network.  Sherlock tells us that in court and it's canon (I'm just reading 'The Tragedy of Birlstone').  Moriarty does the planning, but as he's told us, he doesn't like to get his hands dirty.  He's got people.

I can't see him as part of a terror cell, however - I don't think he's that political.  In that way, I think he and Sherlock really are alike - it's about the challenge, the sheer fun of playing the game.  I would guess that the terrorists who were planning to blow up the plane are simply clients - or prospective clients.  Moriarty trades the information that the government has cracked their code for something else - money, a favour or something to be named when he needs it.  Maybe the terrorists already made the trade on their end - someone had to supply Moriarty with the semtex and know-how in The Great Game.
