[@Erklings25] I also found the connecting plot between one and two to be lacking, despite it leading into Moriarty, I couldn't really see what he gained by getting the gadget at the end of the first film. So if we do start things off with Mary and John meeting, it would be pre-movies so we do have a chance to have Irene appear at some point, as John seems to already know her and Holmes' relationship quite well. I'd wager we could start in the year 1885 maybe?
