Blake's 7, Series Three

Tarrant:
Oh, come on, Avon. Look, we've been through a lot together. We've always been at risk; we've always taken chances. But we've survived because we worked as a team. So what is it you have to do that makes this so different?

Avon:
This happens to be my problem. None of you are involved.

Dayna:
But we are involved. However much you like to pretend you're a loner, you're not really. We depend on each other; I wouldn't be alive now if it wasn't for you, and I'm sure that's true of everybody else. So why not trust us?

Vila:
Look, you don't have to give reasons. You don't even have to explain. Whatever it is, we'll back you up.

Cally:
Or, if you want one of your own cold, rational explanations, we can't afford to lose you.

Avon (poker-faced):
Sentiment breeds weakness. Let it get a hold of you and you are dead.
