The Doctor discovers the perils of bottled water on Mars and accidentally crowns himself Time Lord Dictator.
Short Synopsis
The Doctor lands on Mars in 2059, finds humanity’s first colony, and realizes he’s stumbled into a “fixed point” where everyone dies. Instead of walking away, he tries to save them — and in doing so, breaks every rule of time. It goes about as well as you’d expect.
Extended Storyline
The Doctor, fresh off his space-bus joyride (Planet of the Dead), arrives on Mars. At first he’s delighted — gadgets! domes! history being made! He even hums to himself like it’s going to be a lighthearted jaunt. Spoiler: it’s not.
The colony is run by Captain Adelaide Brooke, who is basically Ripley from Alien with less screaming and more British resolve. The Doctor instantly realizes he knows her name — she’s meant to die here, and her sacrifice will inspire future generations to explore the stars. You know, the usual uplifting history-by-tragedy thing.
Naturally, the Doctor tries to leave. But the TARDIS doors might as well have a sign reading: “Plot won’t let you.” Because soon enough, crew members start transforming into horrifying, water-spewing zombies. Their mouths crack open like broken porcelain dolls, and suddenly the idea of “stay hydrated” feels like a direct threat. The infection spreads fast — a single drop of water, and you’re toast. It’s like The Ring meets Evian.
The base quickly falls apart. Zombies everywhere, water pouring through walls, and everyone screaming. The Doctor keeps muttering about “fixed points” and “laws of time,” but you can see it gnawing at him. He wants to intervene, but he knows he shouldn’t. Adelaide, meanwhile, stares him down like the only teacher you’ve ever feared.
Finally, the Doctor snaps. He declares himself the “Time Lord Victorious” — basically shouting, “Screw destiny, I’m in charge now.” With terrifying determination, he floods the story with Time Lord arrogance, hauling survivors out of the inferno and saving lives that were never meant to be saved.
It works. Kind of. He gets Adelaide and two others back to Earth alive. Victory! Except Adelaide knows better. She realizes that by living, she risks unraveling the very future she was meant to inspire. So, she goes home… and shoots herself. History resets. The Doctor’s triumph collapses into ash.
And that’s when it hits: he’s gone too far. The Time Lord Victorious isn’t a hero — he’s a monster in denial. The last scene leaves Tennant’s Doctor shaken, broken, and more terrifying than any Dalek. Christmas is definitely not going to be merry.
