Martha, John Smith and others in “The Family of Blood”

All you have to do is open it and he's back.

You knew this all along, and yet you watched while Nurse Redfern and I--

I didn't know how to stop you! He gave me a list of things to watch out for, but that wasn't included.

Falling in love? That didn't even occur to him?

[she hesitates] No.

[teary-eyed] Then what sort of a man is that?! And now you expect me to die?!

It was always going to end, though! The Doctor said the Family's got a limited lifespan, and that's why they need to consume a Time Lord. Otherwise, three months and they die. Like mayflies, he said.

So your job was to execute me.

People are dying out there! They need him, and I need him! Because you've got no idea what he's like. I've only just met him, it wasn't even that long ago, but... he is everything. He's just everything to me, and he doesn't even look at me, but I don't care. Because I love him to bits. And I hope to God he won't remember me saying this.
