RANI: You know what I think? I think it's not over, because I don't think she's dead. I really don't. That's not just me being mad, cos I honestly think in my heart and soul that he came back for her. Right at the end, the Doctor came back for his Sarah Jane, and he said, shall we go? Out into the stars? One last trip? And she said, oh yes please. And I think they're out there now, Sarah Jane and the Doctor in the TARDIS, travelling through space and time forever, in a story that never ends.

LUKE: She's the one who told me that Sanjay was looking at me in that way, and she's the one who told me to go and talk to him. And now we've been married for five years. That's the greatest gift she ever gave me. I may have been created by the Bane, but Mum, she gave me life.

DOCTOR: Fear makes companions of all of us.
