DOCTOR: Brigadier, I think our past is catching up on us. Or maybe it's our future.

MASTER: I know this is going to be hard to believe, Doctor, but for once I mean you no harm.

DOCTOR: Like Alice, I try to believe three impossible things before breakfast. Go on.

DOCTOR: Great chunks of my past, detaching themselves like melting icebergs.

JERRICHO: Recently, the Zone has become reactivated. Somehow, it is draining energy from the Eye of Harmony.

FLAVIA: To an extent which endangers all Gallifrey.

BORUSA: We must know what is happening there.

MASTER: Did it occur to you to go and look?

BORUSA: Two of the High Council went into the Zone. Neither returned.

MASTER: So you sent for the Doctor?

JERRICHO: We looked for the Doctor, but he no longer exists. Not in any of his regenerations.

BORUSA: The Doctor has been taken out of time.

JERRICHO: We believe the attempt to lift him from his time stream was unsuccessful. There he must stay until we can find and free his other selves.

MASTER: And if you cannot? The cosmos without the Doctor scarcely bears thinking about.

MASTER: Lord President, Castellan, Chancellor Flavia. This is a very great and, may I say, a most unexpected honour. I may be seated? Now then, what can I do for you?

BORUSA: You are one of the most evil and corrupt beings this Time Lord race has ever produced. Your crimes are without number and your villainy without end. Nevertheless, we are prepared to offer you a full and free pardon.

MASTER: What makes you think I want your forgiveness?

JERRICHO: We can offer you an alternative to your renegade existence.

BORUSA: Regeneration. A complete new life cycle.

MASTER: What must I do?

BORUSA: Rescue the Doctor.

MASTER: What?
