The newly revived Omega runs rampant down The Doctors personal timeline, erasing his life moment by moment. The only hope for The Doctor lies in Eden Citadel, where Omega manifested, but can he journey the Long Road that lies ahead of him in time? And with the deadly Baldandelus still roaming Edens streets, can he make it at all?
- This is an unusual case of The Doctor regenerating in the middle of a story. The Tenth Doctor, who is shot by Baldandelus in Eden, regenerates a mere 25 minutes into the story. Good thing he did really, good old explosive regeneration was more than enough to destroy Baldandelus.
- This is also the first story to establish the physical power of the energy generated by regeneration, with the Tenth Doctor being able to aim the destructive energy ay Baldandelus and disintegrate him, as well as destroy several houses.
