TARDIS: "But between these sounds there came another sound, one so familiar that Lethbridge-Stewart was now certain he was dreaming.

A wheezing, groaning sound.

The sound of time and space parting.

But this time the wheezing and groaning were those of a dying man, the sound warped and painful, as if its source was being torturously dragged into a point it could not, would not, fit.

Compassion started screaming.

The Brigadier swung round his head and looked at the spot where the packing crates stood.  The familiar blue police box was heaving into existence, the light on its roof pulsing insanely, the exterior stretching and warping into shapes that his mind couldn't grasp.

The pressure built.

The sound reached a pitch of screaming nothingness.

The police box could not hold.

The Brigadier slowly flung himself over Compassion, without thought, putting his body between her and the blast.

Which came.

The TARDIS exploded into a ball of flame and matter.

And the sky swept down and crushed them between it and the land."
