A/N: I mention the species "Electant" in this chappie quite a bit... They are from another fanfic of mine titled "Steph's Story" and "The Sparks in the Mainframe". If you want a little more back-story on them...take a look =) As always R&R!

"Oh my gosh," Her hands flew to her mouth as she stared at Rose. "This is before everyone knew. This is before the Doctor even knew."

"Before the Doctor knew what?" He looked at Rose and Bella curiously.

Bella was stock still, a mixture of horror and shock spread across her face. Her eyes met with Rose's, and she knew to stop.

"No-nothing! Now...Doctor, Donna! Let's all send those planets back home!" Bella's shock instantly disappeared and she turned back to the console in front of her, avoiding eye contact with all those around her, Timelord and human alike.

But all eyes remained fixated on both her and Rose. Rose shuffled her feet, awkward from all the attention. She kept her eyes diverted away, even under the strong scrutiny of the Doctor, so no one could see the small tears slowly forming.

"Doctor! Donna!"

Bella's wide grin was back, and so was the sly look in her eyes.

"Let's send those planets back home!" Donna shouted gleefully, turning away from the awkward scene in front of her.

The Doctor remained still. What was going on?

**

The wheels were turning inside Rose's head at a million miles an hour.

How did she know? Who is she? The Doctor said Time Lady...But they're extinct! He said so...so many times...that's why he feels so alone. But there she is...just standing there...staring at me. Why? No one, not even mum or Mickey knows. No one.

What is going on?

**

"Aha!" In another attempt at distracting various species away from the increasing awkward situation that was forming in front of her, Bella let out a cry of triumph.

"What is it?" Asked Donna, who was also eager to continue saving the universe, and deal with whatever this was later.

"I recognise this technology! Finally! Ooohh..Look at that." Bella's eyes scrunched up in curiosity. "That's Electant."

"What?" The Doctor managed to tear his focus away from Rose for a split second; as yet another shock entered his system.

"How do Daleks get a hold of a dead species' technology?" He asked in surprise.

"Did you ask that when the Daleks had the Ark in Torchwood?" Asked Bella quietly, not looking up.

Both the Doctor and Rose drew breath sharply. Bella noticed, but didn't acknowledge it. She continued to stare into the machinery in front of her. The Doctor had had enough. He stalked over to Bella and grabbed her arm.

"Who are you?" He asked.

Bella didn't look at him, but she pulled away from his grip. She turned to the group, humans and Time Lords alike.

"I'm Bella. I'm a Time Lord. I'm seventeen years old and I'm gonna save your lives and the lives of every other human on the planet below." She looked directly into the Doctor's eyes. "Got a problem with that?"

**

"Donna...you grab that...yeah that! Doctor over this side now. It's time to send these planets back home!"

Bella had taken control. No one was standing around anymore; they were working in perfect harmony with her instructions.

"Of you go Clom!" Cried the Doctor.

"So long Adipose 3!"

Mickey and Jack had taken their guns from inside the TARDIS and now had them trained on the remaining Daleks and Davros in the room. Sarah Jane and Martha were watching Bella, Donna and the Doctor with an intense interest. Jackie had moved once again to Rose's side.

"What haven't you told anyone? What haven't you told me?" She asked.

"Nothing!" squeaked Rose, as her voice failed.

"That Bella girl was talking about needing your help, and that she would only ask if the fate of the universe was at stake. Why?"

"I don't know."

But Jackie knew her daughter well enough to know when she was hiding something.

"You're hiding something. From me. Darling, you know you can tell me anything..." Jackie's voice softened as she put her hand on Rose's arm.

"It's nothing!" Rose shrugged her mother's hand off and walked closer to the console, leaving Jackie shocked.

Little did they know that a certain 17 year old Time Lord had watched the entire exchange.

**

"That's it, almost all gone!" Donna was grinning from ear to ear.

This could work after all! She thought to herself.

Suddenly the roof of the vault opened to reveal the Supreme Dalek. It had barely entered the room before the familiar cries of "exterminate!" could be heard. Bella was the first to spot the intruder.

"Look out!" She shrieked, ducking for cover.

The Doctor only just managed to leap out of the path of the Dalek's ray before the console exploded in front of him. That managed to be the only thing the Supreme Dalek could destroy, before both Mickey and Jack had trained their weapons on it.

Bella peeked over the top of the console just as Jack and Mickey fired.

"Ew...Fried Dalek."

She then turned her attention back to the console, and to her horror, the Supreme Dalek had managed to some serious damage. The Doctor's thoughts mirrored her own.

"Argh! No! It's broken!"

"Did all the planets get home?" Asked Martha.

"Ye-no! Just one and guess which one it is."

"The only one it ever is." Muttered Bella.

"But it's OK, I can hook it up to the TARDIS..." And then the Doctor was off and running again, this time disappearing into the TARDIS.

Donna turned back to Bella, who was moving at a pace to rival the Doctor's all over the console.

"What are you doing?" She asked.

"Making sure that every last Dalek never hurts anyone again." Replied Bella, her voice determined.

"But how are you going to do that?" Asked Jack. "In case you didn't notice, we are rather outnumbered."

"And didn't you just say that you couldn't do it?" Added Sarah Jane.

Bella smiled.

"That was before I knew it was Electant technology."

"But that technology hasn't been seen for nearly 4,000 years!" Exclaimed the Doctor, who had recently returned from his jaunt into the TARDIS.

"5,000 actually. But I know an expert."

"How? The Electants are extinct!"

Bella smiled.

"Not all of them. Now...help me with this will ya?"

The Doctor's eyes widened, but he did what he was told.

"Now...If I can get this to go...Oh no." Bella's face fell, but only for a second. Her expression grew soft, and then into one of determination.

"What is it? What happened?" Chorused the Doctor and Donna.

"Nothing! Now get everyone into the TARDIS..." Her voice drifted off as she dashed around the console, her hands working faster than anything the Doctor could pull off.

But no one moved. They could tell that something was wrong. Rose was the first to act.

"Bella?" Rose moved towards the console, and the frantic girl that was dashing around it.

Bella paused, but only to look at the crowd around her.

"Go! I've managed to put it on a timer; we have only a couple of seconds left before this place becomes a Dalek pen and we won't have the key to get out!" She yelled.

On that note, movement did occur. Bella rolled her eyes.

"Come on people! Move, move, move!" Bella pushed Rose towards the TARDIS, and ran back to the console.

The Doctor raised his eyebrows but quickly opened the doors, standing in the doorway to make sure that everyone got inside.

"Let's go! Jackie, Mickey, Sarah Jane, Rose, Martha, Donna, Jack!" The Doctor looked around, and spotted Bella next to the console.

"Come on! Set the timer for five seconds and let's go!"

Bella paused and turned back to him, and pulled something out of her pockets. It was a Sonic Screwdriver, almost identical to the Doctor's, except that it was a more green-y silver colour than blue. There was a tear in her eyes. The Doctor's eyes widened as he suddenly realised.

"But you set the timer!" He cried.

Bella raised her screwdriver, as she put her hand on a lever and pulled.

"I lied. Bye Dad. Say goodbye to mum for me."

A/N: I can't remember who it was, but someone guessed who Bella was, and congrats! You got it completely correct! Kudos to anyone else who guessed as well =)

OMG! Thank you to all that spotted that blaring mistake...I accidentally called Bella "Steph" for a couple of lines! OOPS! I was writing another fanfic at the same time, and it seems that the two crossed over for a bit there!
