• Tegan Jovanka : Doctor, why can't you help them?

  The Doctor : Don't you understand? If I did, it would be the end of me as a Time Lord.

  Tegan Jovanka : What do you mean?

  The Doctor : I can only regenerate twelve times. I have already done so four times.

  Tegan Jovanka : So?

  The Doctor : Don't you see? Eight of them; eight of me.

  Tegan Jovanka : They want your remaining regenerations?

  The Doctor : It's the only way to end their mutation.
