Chapter six.

They crept into the shed, worried that the Keroslates would be in there. But they weren't. Jessie spotted a large trap door and she rushed over to it. "They forgot to cover it. Not very clever, are they?" she whispered, grinning. She tried to open it but it was locked. The Doctor pressed the button on his Sonic Screwdriver and the door clicked open. "After you." he said, his hand out to gesture that Jessie should go down. Jessie grinned and started to climb down the ladder. The Doctor followed. After one minute of strenuous climbing they reached a large cave. "Where are we?" asked Jessie, but the Doctor put his fingers to his lips. Voices were coming from down below…
"We need to act fast! If we don't our whole species will be wiped out in the war!" said one Keroslate. The Doctor and Jessie were crouching behind a wall, watching the Keroslate meeting. "We can't go any quicker. That transmitter is broken and so we can't send the template round this world!" argued the other Keroslate.
"I know. But we can at least go to a smallish city and transform everyone there. At least then we'll have enough people to help us fix it." Silence fell as the Keroslates took this in. Jessie peered in and then almost screamed out with surprise. She fell back against a wall. The Doctor stared at her as if to say "what?"
Jessie was speechless. Her mum was in that room.

"So, she's a Keroslate?" Jessie asked. "Yes."

"But, how come I'm not?"

"Because she was transformed a few days ago."

"You're acting like you knew she was a Keroslate."

"I did."

"How?"

The Doctor looked at her. "Because she didn't blink." he said.

Jessie stared in front of her, silent for once. "So, what were the Keroslate talking about," she said, recovering, "When they said about a transmitter?"

"You're mum is dead and all you care about is what a bunch of aliens are talking about?" he shook his head, grinning, "Well, they're obviously going to use a transmitter to make a window for their planet in every mirror of this planet. Then…well…everyone will…die." he said awkwardly.
"So we need to find this transmitter and stop it happening."

"No, didn't you hear what they said? They said the transmitter was broken. We have to stop them from fixing it…talk to them maybe." explained the Doctor.

"Do you remember what happened the last time when you talked to them." she said, adding inverted commas with her fingers as she said 'talked'.

"Well…yeah. But still. Perhaps that was just Susie Car…" he coughed, "That Keroslate I mean."

"If you say so…"

The Doctor didn't look at all scared. But for some reason Jessie could tell that he was uneasy. He looked at her. "You can tell I'm uneasy about this, can't you?" he said slowly.

Jessie stared up at him. "Why? Why can I tell you're uneasy. I used to think it was body language…but now I realise it's not."

"I think I've worked it out…" the Doctor started, but was cut off short when they saw Jessie's mum coming straight towards them.

"So. Out of the house again are we?" said Jessie's mum. Jessie glared.

"Yes." she said defiantly.

"Don't be so RUDE! You are in the wrong! Leaving the house indeed! You're grounding. And why are you with your teacher…wait a minute. How can you have a school teacher?" asked Lydia. Jessie and the Doctor looked confused. Then they remembered that the Doctor had said he was Jessie's school teacher. But the Doctor had forgotten one important, vital piece of information. Jessie didn't go to school. She was taught by a tutor at home. "You're not her teacher, are you?" asked Lydia quietly.

"No…I'm her friend." said the Doctor.

"Then why did you tell me you were her teacher?"

"Because…I…well…"

Lydia started to shout. "YOU WHAT? YOU DIDN'T WANT TO TELL ME BECAUSE YOU WERE SCARE…"

"SHUT UP!"

It took the Doctor and Lydia a few moments to realise that Jessie had just shouted. She looked as black as thunder and was breathing heavily. "How dare you talk to your mum like that, what do you-" she started, but was interrupted by Jessie.

"You're not my mum. You're a Keroslate! An alien!" she said, her voice wobbling.

Lydia didn't have an answer. She just stormed off towards her house. Jessie stared at the Doctor. "Uh-oh." she said. What was Lydia going to do to Jessie now?
