I think,what we saw in these two episodes,is what was going on in Sherlock's mind the entire time since him and John become friends.He just never felt the need to express his feelings because he never thought he would be separated from him and other people he carred about.But then,of course,everything changed after he come home after TRF.I have a feeling that new Sherlock i kinda like new Doctor.We just need more time to get used to it.After all it has been only a week since TEH.
And we should really brace ourselves because an impact is coming and it's gonna be bad....it's gonna be Moffat bad.

Is nobody going to mention Mycroft exercising?I almost fell out of my chair laughing. :D

First one was better,but still...Amazing episode.I think that we can really see Sherlock has changed very very much in two years time.He realised everyone around him has moved on and found somene except him and it's really bugging him.Our poor Sherlock finally realised he's lonely.
