"Mum, I'm home," Luke called as he entered the big house. Today at school had been interesting and fun and he, Clyde and Rani had a great time for once. But he was glad to be back home.
However, he now felt slightly worried as his mum had not answered. He began searching throughout the house, becoming more and more frantic. "Mum!" he cried out repeatedly as he found that she was not there. She had not informed him that she was going to be out or that there was an alien threat. He quickly reached for the phone and called both Rani and Clyde, asking that they come over immediately.
They ran into the house, not bothering with knocking after hearing how frantic Luke was. "What's going on Luke? Are you alright?"
"Is Sarah Jane okay?"
"I don't know where Mum is! She's not here! I can't find her!"
"Alright, Luke! Calm down, calm down," Rani urged but she couldn't help but feel worried herself.
"Well, she has to be here! Sarah Jane always tells us what is going on so we can help!" Clyde insisted.
"Oi, Clyde, stop it! Luke's already said that-"
"Mr Smith!" Luke suddenly exclaimed. He was already half way up the stairs before Rani and Clyde could even comprehend what he was saying.
"Wait Luke!" The shouted in unison and bolted after him.
They burst into the room just as Mr Smith was activating. "It is nice to see you again Luke, Rani and Clyde. What can I do for you?" the mechanical voice asked.
"Sarah Jane's missing!" Rani and Clyde exclaimed.
"Do you know where she is Mr Smith?" Luke asked anxiously. The Xylok's screen quickly scanned various areas while the three teenagers looked at him anxiously.
"I do know where Sarah Jane Smith is," the Supercomputer announced. "She has been erased."
"What?!" the three said in disbelief.
"What do you mean, Mr Smith? How could she be erased?" Clyde asked.
"It is simple Clyde. Her timeline has been altered throughout her entire life by an unknown entity. So the current Sarah Jane has been erased from history."
"Is there anything we can do?" Luke inquired.
"Yes, I am able to send you back in time to the very first event which was altered."
"Which is?"
"The very first time she met the Doctor." The drawer in his computer opened, revealing 3 watches.
"The watches are disguised Vortex Manipulators. I will send you data, pictures and information through them and they will send you throughout her timestream."
"What did she look like back then though?" Clyde questioned.
A picture of a tall, old man and a young woman appeared on Mr Smith's screen. The man had thick, curly grey hair and a huge nose. He was wearing a green, velvet jacket, a pair of black trousers, a white, ruffled shirt, and a green bow tie. The woman was petite and pretty. She had chestnut-brown hair that hung in curls to her shoulder. She was wearing a dark green jacket, black pants, and a chequered pull-over.
"That was Sarah Jane?" Rani asked, shocked.
"Yes, when she was 23."
Luke nodded in resolution. "Right, what are we waiting for?" Rani and Clyde looked at him and smiled and the three of them placed the Vortex Manipulators on their wrists.
"Sending to 1974." Mr Smith announced, before they disappeared from the time they knew.
