The Doctor began playing desperately with the controls, tryingg to get the ship to function properly while staying on his feet. There was a bright light and then...
Darkness.

In present day Cardiff, the Doctor, Rose, Jack, and Mickey had just finished taking care of the last Slitheen. Rose and Mickey were just about to step out when the door slammed shut. A blinding light filled the room. Rose let out a scream as all went dark.
