Hey everybody I'm back :) I haven't updated anything for months now, to tell you the truth I just having had any ideas. But I had this really weird dream last night which was a kind of cross between Doctor Who and Jurassic Park and I thought of this idea at four thirty in the morning. It starts a little slow, but this is just the prologue. It's set in series 3, before blink and after the family of blood ones. I hope you enjoy it!

Prologue:

Martha tucked her sopping wet hair behind her ears and stood, shivering on the bank of the lake, her clothes strewn with mud and weeds. The rain was beating down in a persistent curtain of freezing water and her clothes were sticking to her numb skin. All she could see were the bodies of the Autuians splayed across the grassland, green algae exploding from their mouths, their noses and even their closed eyes. She was surrounded by people in blind panic, calling for their friends, their relatives or just for help. But no Doctor. Her eyes scanned the crowd looking for the swish of his tan coloured trench coat, but nothing. She swallowed.

Well she wasn't the Doctor, but she was a doctor- or near enough anyway, and it was her duty to help these people. She made her way through the crowds, shuddering in the cold, until she came to a young female Autuian, frightened and alone. Martha identified the signs of the algae beginning to grow in the corner of her mouth, and her heart sunk- it was too late. "I'm sorry," she said, but the woman couldn't just stared at Martha with wide emotionless eyes.

"Martha!" Martha turned at the shout and saw the Doctor sprinting towards her. He grabbed her by the shoulders, his posture showing signs of relief. "Martha, thank God I thought you were left behind." His breaths rattled from his throat as frenzied pants. He swallowed. "It was the government," he said clearly. "They put the bacteria in the water which mutated the algae, don't you see! And only they know what kind of bacteria it is, but now the King's dead too," he paused. "You're soaking, you didn't go in the lake did you Martha, you didn't let the water touch you." His eyes were wide in panic, and she hastily shook her head.

"It's just the rain Doctor, I'm fine. What do we do?" He rubbed a hand over his head, his hair springing back under his touch. He shook his head.

"I need time Martha, I need time it's the one thing I don't have- meet the time lord. I need to test the bacteria on the TARDIS and I need people to stop drinking the water." He froze. "Three hours and the whole planet will be submerged," he said quietly. "I don't have time." Martha took his by the wrists and spoke to him calmly.

"Go and take a sample of bacteria from the lake. The TARDIS is within ten minutes, if you run. I'll sort out here."

"Martha-"

"I'll sort it out," she said firmly. He sighed.

"You," he said. "Are a star." He rested his hands on her waist pulled her close to him, resting his forehead against hers. Her breath quivered in her throat, and she closed her eyes. Was this is? Was he finally going to...

A piercing scream rose above the rest, shattering the moment. The Doctor leapt away from her and his dark eyes widened in horror. "RUN!"
