LEELA: How far now, K9?

K9: Query, mistress?

LEELA: How far have we walked, K9, below the Capitol?

K9: Do you require the measurements in inches, feet, metres, spammers, trigons–

LEELA: Enough, K9.

K9: We have come, in your own terms, mistress, a long way down.

LEELA: I wonder how long we’ve been away from them.

K9: If you require the time lapse in your own terms, mistress, we have been walking for quite some time.
