Maybe I've just gotten used to the voices now, but I think the doubles did a great job. I like Moriarty's voice much better this episode and John's double made me tear up, which is hard to do since I normally feel a bit disconnected from the plot when the voices don't match. I always feel like there's a distinct layering over of the voices, rather than the characters actually speaking the words. But John's double's little whimpering made my heart break a little.
- Sherlock informs Lestrade that Miss McKenzie will need 'an oxygen mask', rather than to breathe into a bag.
- He also calls Jim Molly's 'fiance', instead of ex-boyfriend.
- I was wondering how they were going to handle the IOU thing, but they just put a little subtitle translating what it meant every time it came up.
- The translation of 'the side of the angels' thing is kinda of nice in French. 'I may be on the side of the angels, but don't think for a single second that you have an angel in front of you'.
- I also like that rather than calling him a machine, John tells Sherlock he doesn't have a heart. Which is a nice call back to The Great Game when it's Sherlock himself who says that he doesn't have a heart.
- For the curious (read: me) Sherlock and Moriaty call each other 'vous', which seems a little weird on Moriarty's part considering how intimate he considers himself with Sherlock. Maybe it's a sign of respect. John also calls Mycroft 'vous'.
One thing that I've never understood: why does John go back to Baker Street when Mrs Hudson has been 'shot'? I know he needs to go there plotwise to see that she's alive and well and he's been tricked, but if she's been shot, why isn't he going to a hospital? Or does he think she's dead?
