The Doctor and Kane in “Dragonfire”

But where will you find another home planet?

You're talking in riddles, Doctor. Proamnon is my home planet

Was your home planet. Take a look at your navigational equipment. It's fully operative now.

There must be something wrong.

Certainly not. Your entire people, your race was destroyed 1000 years after you were exiled.

No, no! It's not possible.

Look at the sun of Proamnon. When you left it was a cold red giant surrounded by freezing planets.

There's nothing there but a neutron star!

Your sun turned supernova 2000 years ago. The planets were engulfed in the explosion. Your people were annihilated, your planet obliterated. You're too late, Kane, for your revenge. You have no home. Time has flowed by.
