Hey guys, i'm new here and i just wanted to get across some ideas that i had.
From reading all the posts i've noticed a few theories that have been backed up with fact before hand. For example:
The theory about: fake suicide.
As much as i love Andrew Scott as an actor, it surely couldn't of been two suicides. As stated before with a GIF of Moffat verifying that they didn't both fake suicide on the same roof, either it was truth or he was lying. I also have the idea that if Moriarty was laying there not dead waiting for Sherlock to jump, surely he would want to make sure he was dead and might pop his head over the roof to check? And he might of seen the movement from the homeless network and the big blue air bag.
Another thing that popped into my mind while watching series 3 (which could be the stupidest theory ever) is Sherlocks supposedly 'girlfriend' from The last vow, who is also irish. It could either be ironic but both her and Moriarty are irish and i think it would be cool to see her back an that in some way she might of helped Jim as a way to get back on Sherlock aswell as the newspaper lies.
I am also intrigued by Richard Brook's fast growing beard which is previously mentioned.
Either way i would love to see Andrew Scott come back in any form and they are just my opinions and thoughts...
