"Where the hell is it?" Donna screamed to herself, as she and River ran through the alleys.

"Look" River said in as calm as voice as she could manage "It's no good just running around hoping to stumble across it. That's what he does, we need to think calm and rationally. When you landed what did you see"

"Erm" Donna stammered.

"Hurry, Donna please" River nearly begged.

"Grey, just grey" Donna thought aloud "But it stunk."

"Of what Donna" River pleaded.

"Burning stuff" Donna said hopelessly.

"Oh Donna" River gasped "Oh you are magnificent!" and then she ran.

"What did I say?" Donna yelled after her "Bloody hell all this running" Donna muttered as she followed River

River ran faster than she ever has, climbing over rocks, pushing everything out of her way. She was a woman possessed,, nothing will ever stop her from rescuing the Doctor. Not even a dalek.

Then she saw a sight, a glimmer of hope amongst all the known galaxies. The TARDIS.

"How did you know?" Donna asked, breathlessly catching up.

"The Grunchees, for all their clever genius developed a great was to recycle. That over there" River pointed, "is their recycling system. They burn all their waste and use the fumes to the recyling plant. Clever eh?"

"And that smell is?"

"That smell is the gas keeping the fire alight. That's why the houses are so broken down because the Grunchees moved away from the smell" River explained.

"But why did the Daleks set up shop here and not in the middle of town and collect more Grunchees to experiment on?" Donna asked

"Perhaps they're hiding and don't want to scare off all the potential subjects" River guessed.

Donna felt the blood boil and and temper rage as stormed over to River. "Oi listen, these aren't potential subjects. They're people, green scaly people, and you space girl are gonna help them!"

"Donna I'm sorry but without the Doctor it's hopeless, they've probably killed him by now."

Donna had enough as she punched River to the floor and screamed at her "That man's not dead, do you know how I know? Because he's the Doctor and he saves people and without him the universe is screwed."

"Good to know you believe in him as much as I do" River stood up rubbing her chin where Donna had hit her. "I've never going to test you again, ouch"

"Wait what?!" Donna said shaken.

"I had to see if you were gong to be useful, and he was right again, you are." River grinned the Doctors grin

"You've got a plan" Donna smiled."You legend!"
