Continuity: Dayna is clearly not carrying the rather large bomb she later uses.
Equipment Visible: As Bayban introduces himself to Vila, the shadow of the boom mic moves over the back of his clothes.
Revealing Mistake: When Orac operates the teleport controls, the entire panel shifts from the movement of the unseen operator.
Continuity: Vila's probe vanishes when the block does.
Revealing Mistake: The corridor that Vila shouts down on arriving at the city is a fairly obvious matte painting.
Cally: Vila, we thought we'd lost you.
Avon: But every silver lining has a cloud.
Karil: If you think that what happened in here gives you the right to treat me like some sort of …
Vila: Treat you like some sort of what? I haven't treated you like any sort of anything.
Bayban: My mother…
Bayban: Oh, yes. I had a mother. Wonderful woman. Truly evil person. She had a saying: "Babe," she used to say. She called me "Babe". "Babe," she used to say. "Treat every hour as though it's your last." I'll be back in an hour, Vila.
Vila: A thief isn't what I am, it's who I am.
Avon: Where is Vila?!
Avon: How would you like me to let some fresh air into that rancid little brain of yours?
Dayna: If Vila saw you, who knows what he might do. Run away ... give the alarm ... Tarrant: I doubt that. Dayna: So do I. I think he'd try and kill you. [Tarrant looks at her. Dayna shrugs.] That's what I'd do.
Vila: [To Bayban] You have a reputation for straight-forward mayhem that's second to none. I've been an admirer of yours for um, well, for as long as I can remember. Well maybe not that long, I mean, you're not that old are you? But then again you did start very young, didn't you? I think I feel sick.
Avon: You want me to threaten you?
Tarrant: Why not? I haven't had a good laugh in ages.
Avon: Sensible. You could die laughing.
Tarrant: They stipulated no surveillance devices.
Avon: So you said.
Tarrant: I gave them my word.
Avon: You didn't give them mine.
Vila: Let's get on with it, then.
Avon: No last minute protests? No sudden illnesses?
Vila: I think I've just made the biggest mistake of my life.
Orac: In the light of your previous record, that seems unlikely. Hah! I would predict that there are far greater mistakes waiting to be made by someone with your obvious talent for them.
In City at the Edge of the World, Vila was given a braver role as Michael Keating's young daughter, after watching the show, had said to him "Daddy, you're stupid".
