Sherlock: A Scandal in Belgravia
I thought that was handled rather well. A Scandal in Bohemia always intoned that Sherlock had some feeling for Irene, but I'm glad they didn't have him returning the advances in a sexual way. They also made several references to Sherlock and John being a couple, which made a good balance. I'm a little confused about that line where Irene said she was gay, though. She seemed very clearly bi. I loved all the canon in the beginning. The Greek Interpreter, The Speckled Band, Sherlock posing as a mugged vicar and John raising the fire alarm. I'd love to see fic about the cases they showed, but didn't delve into in the beginning.
