Steven Moffat is known for finding new and creative methods of exploring a monster almost as old as Doctor Who itself. The unnerving corruption of the nanocloud, the horrific Dalek sewers, the revelation that their own casing is built to censor and distort the words and intentions of the being inside. But perhaps most intriguing is his use of the Daleks in relation to his characters, and one specific character in particular. In her duration on the show, Clara Oswald has been placed within a Dalek shell no less than three times. On each of these occasions the circumstances have varied greatly, yet there’s something rather fascinating about such an unusual recurring theme, and even more so the curious manner in which it’s consistently framed.
