Jack: You hid a Cyberman within Torchwood and you didn’t tell us? What else are you keeping from us?
Ianto: Like you care. I clear up your shit, no questions asked, and that’s the way you like it. When did you last ask me anything about my life? …Her name’s Lisa. She’s my girlfriend.
JACK: Suddenly, in an underground mortuary on a wet night in Cardiff, I hear the song of a nightingale.
Miss Martha Jones.
