This, she went through all the trouble of organising what seemed to be the return of moriarty , pretended to be a stranger on the bus who fancied John to make him possibly cheat on his wife , pretended to be his therapist and shot him with aTranquilliser , pretended to be a client of sherlocks , blew up his house , nearly made John or mycroft kill an innocent man in order to spare his wife even though she killed the wife anyway , nearly made Sherlock kill Watson or mycroft ,threw John down a well , revealed she killed sherlocks other brother because they would not play pirate games with her and in the end it all seemed to be just because she wanted someone to play the violin with .
As as I said it was great for the first seventy minutes , outstanding probably but it lacked that moment in the end where Sherlock has it Sussed , I was expecting it to be from the bit where he first meets her and she asks him to look at her and he maybe noticed something which had him in control the whole time or the bit where he is knocked out to work out in his mind what the five minute conversation between her and moriarty would have been like or something
