(After witnessing the events in the radiation room over the monitor link, the Doctor turns to Krang.)
DOCTOR: Well gentlemen, stalemate I think, don't you
agree? Well now, what about a little talk, hmm?
KRANG: You forget we can do what we like with all of you and the girl.
DOCTOR: Oh, quite so, but I'm afraid that won't help save your planet.
(Krang turns to the monitor and addresses the Radiation Room.)
KRANG: Listen to me. This close proximity of our two planets means that one has to be eliminated for the safety of the other. The one to be destroyed will be Earth. We cannot allow Mondas to burn up.
