Hi,

what I have not been able to figure out, is what actually happened on the roof?  Morairty shot himself in the head.. he was dead.  Wasn't he?  In the other, he and Sherlock are enjoying and seemingly appreciating each other,and about to kiss.

I watched it a number of times,and Sherlock's explanaation.  Nothing explains it.  Is Morairty alive?  Are they developing an attraction and appreciation for each other?  Tha woud be an interesting twist.
