SUSAN: I was going to say, why do you trust your people?

1ST ELDER: Why do you want to make me doubt them?

SUSAN: Trust can’t be taken for granted. It must be earned. I trust you, but only because I know you.

1ST ELDER: But Susan, our whole life is based on trust.

SUSAN: Yes, and that might be your downfall. Look you don’t trust the ground you walk on until you know it’s firm, do you. So why trust your people blindly?

1ST ELDER: When I listen to you, you who are so young among your own kind, I realise that we Sensorites have a lot to learn from the people of Earth.

SUSAN: Grandfather and I don’t come from Earth. Oh, it’s ages since we’ve seen our planet. It’s quite like Earth, but at night the sky is a burned orange, and the leaves on the trees are bright silver.

1ST ELDER: My mind tells me that you wish to see your home again, and yet there is a part of you which calls for adventure. A wanderlust.

SUSAN: Yes. Well, we’ll all go home some day. That’s if you’ll let us.

1ST ELDER: I think I will.
