"Nice thinking Kelly." The doctor said smiling. She smiled back.
"Time and a place?" Rose said to the pair of them. They ran up the hall ways to another door. Kelly told them that if they could go through as many doors as they could then reinforce them it would take longer for the slitheen to get to them. The first door banged open. Kelly still held her blaster up in the air. She had a thought.
"Kelly what are you doing run!" The doctor said.
"Hang on doctor she's got a plan never under estimate our Kelly." She pulled the blaster on the slitheen.
"One more move Slitheen and you're in bits!" The slitheen halted.
"Stupid human girl!" it shouted in a husky hollow voice.
"Hang on I'm the one with the weapon I think you're the stupid one."
"You're little friends killed my family."
"You're family, killed all my friends." The doctor shouted.
"There's a difference a friend isn't blood." It shouted.
"No but blood is blood. It's still a life I killed a lot less than you did and what for eh? Money?"
"It's not cheap being rich you know."
"Shut it slitheen I hate oxymorons."
"It shows intelligence."
"You were in every celebrity magazine on Raxocorciophallapatourius why did you need more money?"
"We didn't."
"Oh just for the sake of having it?"
Kelly stood their in the canteen she had already worked out the slitheen was made of Calcium she knew what fought Calcium just like sugar fought carbon. She noticed some vinegar on the side of the kitchen surface somebody had been eating chips she thought but it was no time to think about her dinner. She grabbed the vinegar and unscrewed the top. The slitheen didn't notice as her hand was behind a wall. Suddenly she chucked the vinegar all over the slitheen. It screamed starting to dissolve slowly in pain. They needed more. It was in pain so not concentrating they raided the cupboards for anything acidic. Exactly what Mickey and Jackie did when they needed to defeat the slitheen. They found lemon juice, lime juice, orange juice, more vinegar and pickled eggs. They put it all in a bucket and chucked. The slitheen was dead.
"Flipping 'eck do FBI agents not get heartburn?" Rose said when she was helping clear the cupboards.
"Must cost them a fortune in Rennies" Kelly said rushing.
After defeating the Slitheen they had to do a lot of explaining but were thanked and apologised to for the inconvenience. They went back to the T.A.R.D.I.S. Rose settled down and had a cup of tea and decided to get the problem head on. Kelly had left them to get some privacy. She decided to go and chat up a guard from the FBI she'd spotted earlier.
Rose had tears streaming down her face.
"It's like you said doctor, with Sarah Jane I can spend the rest of my life with you but you cant with me you carry on living. You have the rest of your life to do this stuff. I'm nearly 20, doctor. I can stay with you and never get married or have children. I'd have my best friend because you're my best friend and maybe my cousin. I need to stop doctor I need to start living a normal life. I'm sorry."
"Rose, look I understand it happens all the time. Companions they come and they go but you Rose you're one of a kind. You're amazing." He kissed her a kiss like they'd only shared when Cassandra had her body.
"I'm sorry doctor."
"I love you Rose Tyler."
"I love you doctor."
Kelly had boarded the T.A.R.D.I.S and it was time to go home Kelly had got the guards number but he wasn't a guard he was an agent which she liked the idea of. The doctor dropped Rose on her little estate back in London.
"Rose, I'll miss you so much, the T.A.R.D.I.S isn't going to be as feminine anymore I don't know what I'll do."
"Me neither, Kelly you're great, I love you."
"I love you too Rose." Kelly embraced her cousin and cried. All the thoughts of her childhood flashed back when she hugged Rose. The thoughts of her horrible high school life and the bullies and Rose would occasionally hit one and make it all better because she had the cool older cousin that would stick up for her. She was a sister to Kelly. Everything flashed before her the time they went to the fair together and went on the waltzers 6 times and the doctor told them they weren't a human invention. It flashed back to when they dragged him on the ghost train and he made silly noises. Or the big rides which apparently weren't human either and he was scared. The remarks flashed before her the remarks that he travelled in time and space and defeated aliens but he was scared of a ride that went upside down. Tears rolled down her pale cheeks and she made hard sobbing noises so did Rose.
"Rose you'll always be my cousin but you'll always be my big sister." She said.
"You'll always be my little sister, and if you get any trouble with those bullies again you tell me" She smiled and let out a little laugh but she still sobbed. She could see Kelly any time but the doctor would be gone for good.
"And you look after her, doctor"
He smiled softly
"I will, come here." He hugged Rose. They'd already said there goodbyes in the T.A.R.D.I.S.
"Say hello to Mickey and Aunty Jackie for me?"
"Course I will, you look after him, he'd be dead today if it wasn't for you."
Kelly and the doctor waved goodbye. She watched the T.A.R.D.I.S materialise into nothing and she went inside. Inside the T.A.R.D.I.S the doctor was quiet she hated it when he was quiet. She knew why. She grabbed him and hugged him as tight as she could. They were off into another adventure but they would never forget Rose.
