Tegan Jovanka was sitting outside an auditorium in Brisbane, Australia. She was holding what was probably her hundredth Aboriginal Rights seminar over her years of life. She was standing outside the doors, handing out leaflets to each person that walked in. She would thank them for taking an interest in her campaign and then hand them a leaflet as they continued onwards inside. She turned to look inside the auditorium, all but a select few seats, were taken. The auditorium was almost full. This was her biggest crowd yet. She was so happy that so many people felt the same way she did about Aboriginal Rights. Just then, she heard footsteps approach her, she got ready to hand whoever it was a flyer.
"Hi, thanks for taking an interest in-" She began but as she turned around, the person who had approached her looked nothing like any human she'd seen before. And she thought she'd seen the end of things like this. Just then, the person, or whatever it was, reached for her and she gave a loud scream.
On 13 Bannerman Road, Sarah Jane Smith was up in her attic with her neighbours, children Clyde Langer and Rani Chandra. Her adoptive daughter, Sky, had gone off for a few days to visit Luke, Sarah Jane's adoptive genetically engineered alien son at his university.
"Very intriguing," Sarah Jane stated, looking at the small red stone-like object in her hand, "Where did you say you found it?"
"At the park," Clyde replied, "We were just hanging out, talking about what Sky and Luke would be getting up to when Rani noticed a glow in the tanbark"
"So, like any normal girl who knows about aliens, I got down on all fours and dug that thing up," Rani finished the sentence, "Any idea what it could be, Sarah Jane?"
"Nothing I've ever seen before," Sarah Jane replied, then turning to her brick wall, "Mister Smith, I need you"
At those words, Sarah Jane's wall opened wide to reveal a large computer in the wall.
"How can I be of help, Sarah Jane?" Mr. Smith, the computer, asked.
"Clyde and Rani found this odd glowing stone down at the park," Sarah Jane told the computer as she walked towards it, "I need you to analyse it"
"That can be done" Mr. Smith answered.
Just as Sarah Jane was about to place the stone on Mr. Smith's analysing table, her robot dog, K9 came rolling into the attic.
"Mistress! Mistress!" K9 was calling.
"What is it, K9?!" Sarah Jane asked the dog in a huff, stone still in hand, as Rani and Clyde turned to him aswell.
"My sensors are detecting there are several military vehicles approaching the house" K9 stated.
"Military?" Sarah Jane asked no one in particular, then turning back to Mr. Smith, "Mr. Smith?"
Mr. Smith did a quick scan of the local area, then finally spoke up.
"My scan indicates they are UNIT cars, and they are pulling up to the house as we speak" Mr. Smith stated.
"UNIT?!" Sarah Jane asked, aghast.
She put the stone down on a table to the side and rushed downstairs, followed by Clyde and Rani.
As the three got outside, they noticed three UNIT cars had pulled up alongside the driveway. Several soldiers were stationed just on the street. Sarah Jane stopped them before they got any further,
"I don't know if you got the memo from last time, but I don't want soldiers on my property," she said in a strict tone, then looking at the one who looked in charge the most, "Now what are you doing here?"
"Sarah Jane?" came a familiar female's voice from behind the three soldiers she was staring at.
Sarah Jane looked behind them as a thin dark woman stepped out from behind the soldiers.
"Martha..," Sarah Jane said, "I thought you went freelance, what are you doing with this lot?"
"I still assist UNIT when I can, they thought it would be better for me to aid in this..," Martha looked at the soldiers, "Can we talk inside?"
"You can," Sarah Jane said, "But they stay out here. Off the property"
Martha turned to the soldiers and gave them a nod, and followed Sarah Jane, Clyde and Rani into Sarah Jane's living room. When they were finally sitting down, Martha told them what was going on.
"This is going to be hard to take in," she said, "but people who have travelled with The Doctor are going missing all over the world"
Sarah Jane gave a gasp, "You're joking"
"I wish I was," Martha said, "That's why UNIT called me in to assist them"
"Because you've travelled with him" Sarah Jane said.
"That still doesn't explain why you're here" Rani said.
"And what it's got to do with Sarah Jane!" Clyde said.
"It hasn't just been a few companions disappearing, it's a whole bunch" Martha said, "UNIT are concerned"
"You-You think I'm next?" Sarah Jane asked, finally realising what Martha was saying.
"Any of us could be," Martha replied, "UNIT want to take precautions, and you're one of the people they can't risk getting taken"
"Why?" Clyde asked.
"Because Sarah Jane can help us figure out what's going on" Martha said.
"So, what do UNIT want to do?" Rani asked Martha.
"They want me to bring you back to HQ" Martha said, looking directly at Sarah Jane, "To be safe"
"Cool, I'm up for going back to their base!" Clyde said enthusiastically.
"No," Sarah Jane said, standing up from the couch, "This doesn't concern any of you. You should work on that stone"
"We could help!" Clyde said.
"Yeah, what about Jo? She could be in danger too!" Rani said.
"Jo?" Martha asked.
"Jo Jones, formerly Grant" Sarah Jane reminded Martha.
"As far as we know, she's still out there," Martha said, "But she's a hard woman to track down"
"I've got Santiego on Spacebook, I could find out where they are!" Clyde retaliated.
"NO!" Sarah Jane yelled, "If whatever is doing this finds out you're involved, it could take you too. I'm not going to let that happen"
"Besides, if UNIT's having that much trouble tracking them down, they're probably in a really remote area. Unlikely to be any service there" Martha said.
"That makes sense..." Rani said.
"Yeah, but-" Clyde began but Sarah Jane cut him off.
"No 'but's," she said, "Upstairs, work on the stone. Under no circumstances do you try and contact Santiego. Understood?"
"Yes, Sarah Jane" Clyde and Rani said in unison as they went upstairs.
"Shall we go then?" Martha asked as she got up off the couch.
Sarah Jane gave one last look up the stairs .
"They'll be fine" Martha said.
"I know," Sarah Jane replied, "But I need precautions"
With that, she texted Mr. Smith to block access to Spacebook on all electronics in the house, including himself and K9. She gave a wide grin as she followed Martha out the door.
