Dalek #1:  We could let this catastrophe destroy the Thals .
Dalek #2: Will they let themselves starve to death ?
Dalek #1: No . I feel preserving our prisoners was a good idea .
Dalek #2: And an arrangement to bring the Thals inside our city an even better _ one _ .
Dalek #1: We 'll let our prisoners sleep and then give them food . After that , we can plan .
Dalek #2: Why not begin now ?
Dalek #1: Because the lapse of time , the relation of sleep , the provision of food , all these things will give them a false sense of security .
