[The Doctor literally finishes his explanation when he hears the slap and Narvin crying out for him. Knowing they can't afford to lose any more time, he jogs over, and smiles charmingly over Narvin's shoulder--well, it's more like over Narvin's head since he is that much taller--at the human the other Time Lord has tried to assist.] Sorry, don't mind him, he doesn't get out much; can't even be bothered to change out of his nightgown! We're here to help you. From what, well, it's all a bit complicated and there'll be time for explanations and more slapping later, but you've got to trust us if you want to make it out of here.

[Reluctantly, the woman nods and slowly puts down her hand that she had had ready to fend them both off.]

Brilliant! Now, Narvin, explain to the nice woman as kindly as you can how she can help you free the others. That's all you need to do: be friendly. [With a clap on Narvin's shoulder, the Doctor bounces away to free another person on his side of the body-print machine chambers.]
