He cried.

I`m pondering on who phoned John Watson that Mrs Hudson was dead? Its part of Sherlocks plan to get him out of the way maybe? And Watson would have surely mentioned if it was Moriarty. Maybe it was Mycroft, and maybe he has something to do with this?

Was it the fact that he asked molly for help?

Remember he said “thats what people do….leave a note…” perhaps he saying that watson needs to find something out, perhaps something to do with the science equpiment sherlock had that mrs hudson talked about?

what we missed:
Sherlock put his arm to his mouth briefly, a few minutes before the fall. Any sgnificance, perhaps?
His crying?
Leaving a note?

And you know how the little girl was terrified of Sherlock, maybe Moriarty used a mask of Sherlock. Mask of sherlock?

The last three are ones I’ve seen a lot on the internet. BU-BYE!

Crying, i’m sure.

Does anyone think that Moff would actually admit if anyone came up with the right clue?  I wonder if he is just doing his usual chain-jerking routine.

Just before his final confrontation with Moriarty, Sherlock meets with hospital pathologist and recurring character Molly Hooper. Molly has an unrequited love for Sherlock and everyone, including he, knows it. He tells her he thinks he’s going to die and asks her if she would still help him even if all his greatness turned out to be a lie. She agrees. Molly is the ace up Sherlocks sleeve because she’s loyal to him despite the careless and often cruel way he treats her. This means that even Moriarty doesn’t consider her someone he cares about which keeps her safe from his gunmen. This blind spot is all Holmes needs to prepare for his little fall.The next two parts of the puzzle come during the final scene and are a bit trickier. When Watson arrives at the hospital and see’s Sherlock on the roof he tries to get to him but Holmes tells him to go back to where he got out of his taxi, ostensibly to stop the gunman from shooting him. What this actually does is place another, shorter building between the two, so Watson can still see Sherlock jump, but not land. To do that he has to round a corner onto the street. Next clue is the easiest to miss but possibly most revealing. As Watson rounds the corner to see Sherlock’s body, a flatbed type truck with an open back full of what appears to be bags of rubbish pulls away from a parked position right in front of the body as a team of strangely fast doctors and nurses rush over.I know it’s a hospital, but they do seem to arrive almost instantly and cart him back inside with ridiculous speed.Thus I surmise: Sherlock knew that Moriarty intended to leverage his friends against him to make him die in disgrace and therefore engineered the entire rooftop encounter. He knew Moriarty would sooner die than let Sherlock beat him which is exactly what he did. He showed Moriarty that as long as Moriarty was alive Sherlock had another option to save his friends without killing himself. He even let Jim believe he had fallen for the computer key code even though a basic binary translation of the code resulted in the message “there is no key”. This explains why he seemed to have been beaten when in fact he was just playing dumb. The next part is the jump. I believe that Sherlock arranged to have the truck full of bags be parked outside the hospital so that when he jumped he could land in it to break his fall, he could then jump out and onto the pavement where he could bash his head and play possum. This is backed up by his not wanting Watson to see where he would land. Another thing backing this up is the fact that the truck drives away from the scene fairly quickly. I don’t know about you but if a body landed beside my truck and a crowd started gathering I’d get out to see what the hell was going on.I believe that Sherlock convinced Molly, possibly with the help of Mycroft, to help him survive a suicidal jump by way of padding his fall, then using her influence and Mycrofts resources, get him declared dead and buried. That just leaves the Why. That’s not so difficult. Moriarty may be dead but his network still exists and poses a threat to Sherlocks loved ones. The gunman with Watson in his sights has a good view of Moriarty blowing his brains out but still keeps his sights trained on his target, Watson, until the all clear. Sherlock still needs to be presumed dead so he can go about dismantling any systems Moriarty had in place and to ensure his friend’s safety.

A few musings: 
Possibility that kids were pointing at John not Sherlock.Donovan in bed with/blackmailed by Moriarty. Or else, what’s her problem.Sherlock made the tea Sherlock doesn’t/and didn’t drink tea,Their Final Problem is being alive, they both have to appear to die to continue the game. Living creates an interesting situation, Sherlock has been exposed as a fraud and has staged his own death, it will get the papers and nation’s back up as he has made everyone look stupid (again!) So all the pieces move back to square one.Sherlock get’s it wrong/is one step behind Moriarty  ie: the key/no key business…nope I don’t buy it he set everything up and I believe they both know it, they are playing out the game to it’s natural conclusion. Therefore Moriarty isn’t dead either.” It’s a magic trick”: Misdirection, distraction, suggestion, everything’s staged, John’s time of arrival and  viewpoint, lorry = soft landing, the bike stalls John and possibly he is drugged so he expects to see dead Sherlock, rubberball slows pulse. Molly in morgue duties death forms etc.Don’t believe he asked Mycroft for help unless he’s going to be forever in his debt in next series, it would ruin the dynamic of their relationship.SH cried out of vanity

Moriarty says he’ll ‘burn’ sherlock, could that be as in ‘copy’? But, please God not a ‘face-off’ type idea.

Having watched over and over again, is it the fact that Sherlock was actually calling John on his mobile, he prefers to text, his own words from series 1, episode 1, after watching both series, the only time he does is when he is called on the pink phone in the great game, he doesn’t make any calls. Is it possible Sherlock recorded the conversation he knew he was going to have with John and had the double in his place, (the person who kidnapped the children), convincing John that he was speaking to Sherlock and thinking it was him on the roof?
We’ll find out next series I guess!
