If there is, were are damn lucky. However, Martin and ESPECIALLY Benedict are ridiculously busy, and their fame levels are shooting up quickly. They’ve both made it to the big screen in some very big films in some very big roles, and I don’t know if series four is doable. My guess is they will end it at series three, episode three. There will be no cliffhanger, we will just be left to assume that things go on as usual: Sherlock and John solving cases, Anderson lowering the IQ of all within a mile radius of him, Lestrade not giving a fuck, Mrs. Hudson being awesome, and tons and tons of subtext.

Now I actually want Harry to become part of the show. When reading Performance in a Leading Role, she is the only person I could imagine as Harry.

He can barely cope without a case. He will have gone (potentially) three years having to lay-low; no cases, probably no London, no John. In an instant, he had the three most important things in his life completely stripped away. I’m thinking he will be on very hard drugs, more addicted than ever, and he will probably on them almost constantly. Drugs were a bigger part of Sherlock’s character in the original canon and knowing the fanboyness of Moffat and Gatiss, they’re going to work it in even more. With the ACD canon, if his mind was not running at a million miles a minute, he was on cocaine. Cocaine or not, I think it will be something extreme— it’s not like he would have anybody around to stop him. Unless he is, for some reason, still seeing Mycroft regulary, he will not be able to control himself. That’s why Mrs. Hudson, John and Mycroft were always trying to help him quit his smoking habit, and it had been implied that it used to be something stronger than cigarettes. Although he has always been so logical, brilliant, and composed, addiction is his weakness. Like I said, I think he is going to be in a terrible state that takes him a long time to recover from, and it is going to be very hard on John who will have to (and want to) be the one to help him through it. If this does happen, I think it will be very sad. 

I don’t think Sherlock was able to predict what was going to happen on the roof. I believe he spoke to Molly beforehand because he thought he could jump as a last resort. He must have known the exact height of the building and some certain ways to fall which, if mimicked correctly, would allow him to possibly survive. As many of us noticed, he fell in a very strange manner, almost as if he was flailing. He most likely used one of the hinted-at methods for stopping his pulse which have been very popular theories on Tumblr (i.e. the rhododendron ponticum or the rubber ball trick). Molly would have prepared everything for his fall, and been ready to nurse him back to health to the best of her ability and help him escape if he lived through it. He knew that if worse came to worse on the rooftop and he was about to be killed, he could have thrown himself off of the building and tried to fall correctly while having his pulse stopped. Moriarty killing himself was a huge surprise to him and he truly was at a loss at that point. I’m assuming everyone who brought him in was in on it, homeless network or not. I think everything on the roof— the panic, the tears, and the willingness to die for his loved ones was all real. He probably knew that he had about a 50/50 chance of survival, if not much less, and that he was really saying goodbye to John either way. I think so many of the other little things, like the biker, for instance, were honest-to-God accidents thrown in there by Moffat and Gatiss (but mostly Moffat) to have us do exactly what we’re doing and theorize WAY off track so there is more of a surprise when season three comes around. I think 90% of it is still a huge mystery (what is throwing me the most is what happened to the body of Moriarty and why it isn’t in the news, and whatever the hell happened when they were locked in the cell together),  but this is my general idea of what happened. 

Food for thought.

Why did he act so frazzled when Moriarty said he picked the perfect place to do it? And he was all “Do it? Do… do what?” He obviously knew and it is not like him to be frazzled.

Why wouldn’t Sherlock check his phone in the beginning when he always answers texts immediately? 

When he found the camera in 221B, why did he look so sad about it when John wasn’t looking? Also, why did his own image come up on his computer when he was holding it?

What is the point of IOU and is it connected to John saying “I owe you so much?”

Why is nothing ever said about the body of Moriarty being found?

And, somebody already addressed the fact that Sherlock was hyperventilating on the roof and that could have been significant and even helped save him. It’s quite unlike him.
