whocameos: My absolute favorite thing about BBC Sherlock is how in series 1, you think it’s a show about a bunch of normal people living with a sociopath; but by series 3, you realize it’s about a clever landlady who used to work in a drug ring, a pathologist who convinced the world’s most terrifying criminal mastermind to watch Glee, an ex-CIA assassain trying to rebuild her life, an ex-army medic with an adrenaline addiction who laughs at crime scenes, a powerful British government official who cares more about his little brother’s safety than the security of the entire country, and an emotional genius who secretly loves dancing while he suppresses his feelings to prevent his heart from being broken.
