"TARDIS... Turlough... Tegan... Three T's... Must remember... Mustn't forget... I recognized their technology, of course." The Doctor stumbled through the jungle, chatting amiably to the stalk of celery on his lapel, his head still ringing from the encounter with the Mara. "I'm afraid their species name escapes me, you see they're terribly old. Inhabitants of one of the Home System worlds... Legend has it they used to set up defenses on worlds that were not ready to fend off temporal threats... Vigilantes of a sort. They were far ahead of Gallifreyan time technology, at the time, so to speak." He tugged at the bright pink band that encircled his wrist as he walked, absently swatting aside leaves and mosquitoes, slowly coming out of his daze, eliminating the anesthesia from his system.
The vegetation around him had blackened. Rain and moisture soaking into the charcoal and chemical residue that once been crowded with leaves and home to a billion creatures. In the smudged distance, he caught sight of familiar blue speck. The incessant sounds of birds and insects faded away as he stumbled toward the center of the destruction, picking his way through the twisted stumps and spines of the exterminated trees. "Yes, well, good question, Joanne. They were, ah, well, all destroyed... Omega blew up their sun to create the Eye of Harmony... Typical Time lord arrogance of course... Microsoft likes to thing they started the policy, but..."
He stood before the TARDIS and paused to gnaw at the pink band with his teeth. He was uncertain of its exact technological function, which bothered him slightly, but even more so, the thing did not go at all with his outfit.
The band was the only trace of the event, the only piece of evidence that the aliens had ever been there. Their ship had vanished. They had released the Mara into the jungle and then dumped him, still partially tranquilized, in the jungle where they'd found him. Apparently, they didn't consider him worth bothering about. Neither had the Mara; it had ignored him completely.
The Doctor felt vaguely insulted by that.
The subtle click made him look up from the bracelet.
"Ah... hello." The rifle was pointed directly at his head. The boy holding it was clearly Vietnamese, his clothes smeared with soot, his face streaked with tears. Blood seeped down his left leg from some unseen wound. "How do you-" The Doctor began heartily, but paused. Instead he raised his hands slowly. "I'm the Doctor."
The little boy's eyes widened in surprise as he comprehended the Doctor's words, but instead of lowering the wound, he held the weapon closer, tightening his finger on the trigger. Confused.
"Ahh..." The Doctor tried to appear as nonthreatening as possible; clearly the presence of the TARDIS, the napalm attack and a dandily dressed fluent foreigner was a bit much. He needed to appear as friendly and charming as possible. "Probably wondering who I've been babbling to this whole time, very understandable, clever chap like you, if I may introduce you to," the Doctor waved a hand to his lapel, "this is Joanne, you see..."
At the movement, the boy fired.
The bullet bounced off of the TARDIS.
The other TARDIS.
The Doctor blinked.
The boy dropped the gun and fled into the forest.
The scarred landscape was filled with TARDISes that had appeared instantaneously out of no where, filling the ruined jungle, centimeters apart from each other. A wall of blue. Dozens. Hundreds. Thousands. A valley of blue police boxes.
Even the humidity level had dropped, so drastically had the time ships altered the landscape. There was no breeze, no birds.
"This can't possibly be good..." The Doctor muttered. He stuffed his hands in his trousers and spun about on his heels, taking in the thousands of identical TARDISes.
Then, as one, with one gargantuan creak, the doors of every police box opened.
A thousand different Doctors stepped out.
A handful he recognized. A thousand more he didn't.
As one they opened their mouths, their lips crying out silently for help.
And, as one, they fell to the charred ground as a million silver snakes burst from their skin with a sickening popping noise and began to devour them.
After the silver worms finished their feast, the corpses stood once more on their feet and turned to the Doctor, the mouths of the snakes snapping hungrily for him.
But he had already gone, and there was a thousand TARDISes minus one in the rugged valley.
