Blake's 7, Series Three

Tarrant:
Ah, Cally - I've been going over that theory of yours about the teleport bracelets boosting each other. As you're aware, it doesn't make sense.

Cally:
You have a better one?

Tarrant:

Cally (sarcastically):
I seem to be more clever than I thought I was!

Tarrant:

Avon:
Shut up, Tarrant.

Tarrant (angrily):

Avon:
