This is a great example how to do an interview. Interesting questions, witty comments (love the thing about Steven going on holiday while Benedict keeps talking).
The best thing for me is Benedict saying that for him the most interesting part is not the survival as such but how Sherlock copes with coming back into a changed world. I am really excited to see him doing that. 

Solar, one request - could you put the spoiler warning in the title as well? Thank you.  

Exactly. And I think this might show what Benedict does so very well - ambivalent feelings, a mixture of sarcasm and vulnerability and a bit of humour. 

Thought this article was brilliant.  I'm excited about the fact that the focus of S3/E1 will be on getting the boys back together.  I also liked that Ben said Sherlock has 'regressed' without John there to put the brakes on. And ohhh...he comes back to an empty flat.  Now we know John did leave and apparently Mrs. Hudson didn't rent it out.

Agreed.  The solution of how he survived will be fascinating I'm sure and I am looking forward to it;  But the heart of our story is our boys.  What happene after Sherlock fell, what happens now?  This is what makes me shiver with anticipation..

A very good interview with new questions and new answers.
We wondered about Sherlock and vanity in a thread here, too. And Mr Cumberbatch's answer is not something we thought of.
