Radio Times just posted a slightly-maybe spoiler that Lara Pulver has hinted that we might not have seen the last of the Woman. Read: http://www.radiotimes.com/news/2013-09-09/sherlocks-lara-pulver-on-series-3-return-i-didnt-say-you-wouldnt-be-seeing-me
I have a theory that we’ll see at least a flashback with her and Sherlock when they’re both in hiding. They will be monitoring things on the outside world together. Would they be doing anything else? (Hint: Boink! Boink!) I guess we’ll have to wait and see.
Oh my poor Molly, this could not be good news for you :(
