To prevent myself going into Lestrade withdrawal after seeing the miniepisode, I have to ask, is there much Sherlock/Lestrade interaction in the episode. I'm a big fan of their father/son vibe that shines through occasionally(ie, Study in Pink).
Also, for my inner Mycroft fangirl, does Mycroft show any genuine emotion in this episode, to anyone? And do he and John have any interaction at all?
Feel free to ignore these queries if they're too spoilery : )
