Hello! A brand spanking new chapter! This is a bit of a filler but leads on to some stuff. I had a hard time writing it and have been focusing on The Doctors which is my crossover fic (which you are welcome to read ;) ) Anyway, enjoy!

The two ran through the maze of dank and twisting stone passages, the screech and clicks of their pursuers ringing in their ears. Reaching a crossroad, they faltered and the Doctor stumbled and began to lose his footing, River grabbed onto the tweed sleeve and jerked him along as they dove down the closest tunnel.

"Hurry, Sweetie!" she cried, twisting round and pushing him in front of her, her heels clattering on the stone and dirt tunnel floor. He ran, bringing his arms up to help with his speed and his mop of brown hair was now plastered to his face by a clear sheen of sweat as they ran. Behind them, they heard a load scream of a Zarbi, making them stop. River gave her husband a tired smile as if to say "Must our dates always go this way?" He nodded breathlessly, his chest heaving. The Doctor was wide eyes as he lent against the wall, a small smile on his face. He always loved the chase. Didn't always like what was chasing him though; hence the chasing and mind you, it took a lot out of you. But neither husband nor wife could deny it was fun! River pushed her hair behind her ear, the curls having a mind of her own and she then grasped the Doctor's hand. He looked at her, his mouth moving wordlessly. Then River put a finger to his lips.

A slow, moaning menagerie of clicks and clacks were vibrating through the matrix of passages. The Doctor was sure that the Zarbi was close. His suspicions where confirmed when, from behind them, a thick skinned Zarbi came out from a tunnel; mandibles working furiously, its legs vibrating to warn his ,or her, or in fact it's brethren. He gulped and tugged on River's hand.

"Run! River…Run!" They charged down, the ferocious insect following at a great pace. River couldn't help but laugh as she ran for her life. This was what she craved, excitement and adventure and him. Always him. The laugh was infectious, and soon the Doctor was giggling like a schoolboy as he too, ran for his life, like an eight legged giraffe (most commonly located on the planet Giri) all legs, no brain. He stumbled, charged and tripped along, the Zarbi gaining on them. River's inside's screamed as did her voice.

"Doctor!"

"Yes!" He shouted in front of her, his hand still clasped in hers. He used a thumb to stroke her palm.

"What do we do?"

"Well, the running thing is good!"

"I agree but I meant weaknesses, they took my gun."

"You brought a GUN?" shouted the Doctor, acting appalled but inside scalding himself. Of course she did. She was River, nice hair, clever. And doesn't mind shooting things! Honestly, Doctor!

"Yes!" she rolled her eyes as they ran. They ran right and then left, the Zarbi screeching and charging in their wake. The Doctor made very little sound as his slim legs sped it forward through the dark cave from which chunks of rocks were threatening to collapse down heavily on top of them. River was less silent, her heels leaving spall prints and hard, echoing 'clips' as she ran along. The Doctor wiped his head round. He saw the Zarbi. It was fast, its legs carrying the great body. He saw River. Her face was screwed up but with more frustration and effort than fear. Atta girl.

"Quick, this way!" He shouted. His hand scraped along rock. Their hands fell apart. They ran. Ran for their lives. They charged right. Down a narrower passage. But the Zarbi came to. The rock fell apart as the Zarbi charge. It crumbled to make way for him. The Doctor was still ahead. River only saw stone, dirt and tweed. Breaths came in heaves. She passed him.

"Hurry!" The Zarbi let out a tumultuous roar. The Doctor looked back. The Zarbi was close now. He looked forwards and River was gone.

He saw a chasm, deep and dark. He blinked trying to see the bottom but couldn't. Letting out a roar, he twirled, grabbing the Sonic from the inside of his jacket. Pressing the button down so hard that it hurts, the sonic jumps to life, letting out a high pitch sound. The Zarbi shrieks and flees.

The Doctor then turns around, hardly daring to breathe. He kneels, a movement which seems to go on for an age and his hands grasp the ledge.

"RIVER!" He screams.

Cliffhanger...literally in a sense. Anyway as I say every chapter: PLEASE REVIEW! They make me so happy ad it spurs me on every time.
