so after scutinizing each and every clip of the final episode I have found that there are so many loose ends that there are many possiblities to where each one fits in the grand scheme of things. 
However, to me the thing that stood out the most was the clip where "sherlock" was being taken to the hospital. After speading some time trying to pause at the exact moment i wanted to see, i realiazed that the guy being taken into the hopital was not sherlock. he looked kinda like joseph gordon-levitt, but was definatively not sherlock. After reviewing the episode to find a person that kinda looked like joseph gordon-levitt, I found this person at the end, right after sherlock fell coming next to him with his hand suspiciously in his chest pocket, as some other person's reichenbach ideas mentioned. Now that same guy was seen taking the bed to the hospital, but his back was turned. it's hard to say whether anything of substance could happen withing that short amount of time, but it is quite suspisious about the not sherlock person. If anyone's ideas coincide with mine, please let me know.
Can't wait till season 3!!
