"Uh, Sarah, why are you in Limbo?" Clara asked, she knew that humans couldn't live in Limbo there was no food no water in fact, there wasn't anything there.

"Well I was tracking down a Slitheen in London when I was sent here. I have no idea of how I got here." Sarah Jane explained looking around then looking back at Clara. "And now that I've told you my name, what is yours?"Sarah Jane asked.

"I'm Clara Oswald." Sarah Jane smiled and said. "Call me Sarah Jane." The older woman told Clara.

"Well that's it for the chit chat ladies." The Doctor said and pointed towards a slimy green thing that was at least six or seven feet tall, it had really big black eyes and it was blinking sideways. The thing was running straight for them.

"Alrighty, in the TARDIS!" The doctor yelled.

"Its been a while since I've been in here, I see you've redecorated." Sarah Jane said smiling and looking around as she walked in.

"Oh so many memories." Clara was confused, she knew there had been people before her but see never met any of them.

"Wait you've been her before?" Clara asked Sarah Jane confused.

"Yes I have, I was one of his companions. At least, in a previous generation."

"Yes, yes I said we are done with the chit chat ladies. Now Sarah Jane we are taking you home and leaving the Slitheen in limbo." Sarah Jane looked unhappy at this.

She had just seen the Doctor for the first time in years and he wants to drop her off? She had been tracking that Slitheen for months with Luke, that Slitheen had taken her most prized possession, Luke, her adopted son.

"Oh no you are not taking me home, that Slitheen took Luke!" The Doctors face went from emotionless to confused then to understanding."Wait who's Luke?" Clara asked, she had never heard of Luke or Sarah Jane. "Luke is my son. We've been tracking that Slitheen's activity for months and a week ago the Slitheen came to my house and took Luke. I had Mr. Smith do a global scan of earth and he isn't on earth." Sarah Jane sounded worried and she was worried if Clara had a son and a creepy looking thing took him away Clara would be doing everything in her power to get him back, and Clara was going to help Sarah Jane get her son. Clara had only one question.

"Who is Mr. Smith?" She asked."An alien super computer." She replied.

"An alien supercomputer," Clara said absentmindedly looking down at the TARDIS's console. "I've seen and heard weirder."

"Ladies! I said enough chit chat. Now, we are going to find Luke and bring him back to earth."
