I'm so happy you enjoyed the episode. :-) I think some of my favourite moments were the scenes Mycroft and Sherlock shared. A lot of fans have issues with the way Moffat wrote Irene Adler, but I really liked Lara Pulver's portrayal - and not just because she reminded me of Fräulein von Hoffmanstal in The Private Life of Sherlock Holmes. *g* I think you hit the proverbial nail on the head with your analysis of the Sherlock/Irene relationship. They do seem to need each other on a cerebral level. They each feed off each other's brilliance.
