Alarms were blairing all over the place.
"We've got to save CAL!" Mr Lux shouted.
"What's CAL?"
Seconds later, River had opened the gravity platform and they were in the core of the planet, at the main computer.
They were running out of time fast.
"Help me. Please help me." came a voice.
"Is that a child?" River asked, wide-eyed.
Mr. Lux pulled a lever and introduced them to CAL.
It was a tragic story. River's hearts broke as she listened. They had to save her. She'd already saved so many lives...
The Doctor rushed to the computer, talking himself into a solution.
"Easy. I'll hook myself up to the computer and she can borrow my memory!"
Panic shot through River like icy water.
"Difficult. It'll kill you stone dead!"
He brushed her off like it didn't matter.
"You'll burn up both your hearts, I don't think you'll regenerate!" she shouted, close to tears. He couldn't die here. She couldn't let him. What would happen to her? What would happen to the universe?
He began giving them instructions, ignoring her pleas.
God, he was so hard to deal with!
"...and Professor can I just mention in passing, as you're here, shut up." he said, moving on to begin wiring.
She was furious. How dare he talk to her like that?!
"I HATE YOU SOMETIMES!" she shouted, storming out to help Mr. Lux free up computer space.
At this moment, she just wanted to let the idiot die.
She needed a plan.
