Blake's 7, Series Two

Durkim:
Servalan, by design or accident Star One is failing.

Servalan:
There has to be another explanation.

Durkim:
There isn't.

Servalan:
And if you want to keep your job you'll find it.

Durkim:
Why won't you face the facts?

Servalan:
Because I'm not convinced. And even if I were, there would be nothing I could do about it.

Durkim:
Well, surely under the circumstances you could get clearance to put a team in.

Servalan:
Star One is the most secure installation in the Federation.

Durkim:
I know that.

Servalan:
Do you know why it's so thoroughly secure?

Durkim:
Well, presumably because knowledge of its location is severely restricted.

Servalan:
No! Knowledge of its location is non-existent! (Her tone is one of anger and desperation) Durkim, no-one knows where Star One is! No-one at all!
