Amy: Sorry, did I do something wrong? Because I'm kind of getting mixed signals here. Doctor: Mixed signals? How? Amy: Oh, come on. You turn up in the middle of the night, get me out of my bed in my nightie - which you then don't let me change out of for ages- and take me for a spin in your time machine? No, no, you're right, no mixed signals there. That is just a signal. Like a great big Bat Signal in the sky-- "Get your coat, love, the Doctor is in".
