A/N: This is going to cover Rise of the Cybermen and Age of Steel. It will coincide with the plot, but once again, focus more on Katari's thoughts, so just keep the main plot in mind. :)

Gas masks had fallen from the ceiling as the TARDIS crashed. Katari huddled on the floor, preparing for more to come.

"Everyone all right – Katari – Mickey?"

Mickey was around the side of the console, "I'm fine. I'm okay, sorry."

The Doctor was staring at the console as Mickey and Katari stood, "She's dead."

Katari watched in horror as smoke rose from the TARDIS, and looked back to the Doctor, who was in awe, "The TARDIS is dead."

I am stuck wherever we are right now. Whatever century, or planet… Katari's breath caught in her throat. "You can fix it…" She meant it as a statement, but it came out a question.

"There's nothing to fix. She's perished," the Doctor was carefully taking note of the console, "The last TARDIS in the universe…extinct."

"But, we can get help…" Katari prodded.

"Where from?" The Doctor looked hopeless.

"Well, we've landed – we've gotta be somewhere."

The Doctor was shaking his head, "We fell out of the vortex, through the void, into nothingness. We're in some sort of no-place... the silent realm... the lost dimension..."

Mickey grinned, the door to the TARDIS cracked open, "Otherwise known as London."

Katari's heart skipped hopefully for a moment, until she saw the Doctor. He looked relieved they weren't in nothingness, but she could tell the TARDIS's death was still weighing heavily on his mind. It meant he would be stuck forever; no adventure, no traveling.

The Doctor was now talking to Mickey, "Just as we left it."

"Bang on," Mickey looked pleased.

"And that includes the zeppelins?"

The poster had moved. It was almost as if she had seen her father alive for the first time in twenty years; even if it was a poster. Katari had always wished that she had known Rose before she and the Doctor had gone back in time to the day of their father's death. Pete had visited Katari every year on her birthday until he died. She had been seven at the time of his death. He hadn't been able to visit that year because Jackie was eight months pregnant with Rose at the time of her birthday in March.

She sat on the bench, trying to recall her few memories of him. He had always swept in to their home with such force, as if a tornado had taken up residence in their living room. Several years after his death she had overheard her mother talking to a friend. The subject of Katari's father had come up and her mother was explaining, "Pete was a good man, deep down. Always regretted not seeing Katharina more than once a year, but given that I had chosen to move here to Virginia, there wasn't much more he could do." Katari remembered hearing her mother sigh deeply, "I think he was secretly grateful for the move. He was always terrified of being a bad father. Being an ocean away from his daughter gave him a way out."

He had always bought her the best toys. Toys that were the most popular here, but that weren't popular in England, so they were cheaper and easier to get. She was one of the only kids in her class to have a Cabbage Patch doll as they were not nearly as popular in Europe. Elizabeth, a red-headed toddler Cabbage Patch, still sat on a shelf in her bedroom at home, a reminder of the hours she spent playing with her.

"My Kat-a-rat!" Her father would twirl her in the air as she laughed loudly. She had asked him one year why he didn't move in with them.

He had looked around nervously, "Oh, sweetie, Daddy lives very far away. I can't leave. I love you, very much, I do. But…well, I belong there."

Katari had since realized that he was already with Jackie at the time of that question. That it truly was out of the picture.

But the man who was here was not the man who had called her Kat-a-rat. The man here didn't even know that she existed. Did she exist here? Had the Pete Tyler and Marie Malloy of this universe had a baby out of wedlock, had they even dated? And if she did exist, what would that mean if they were all stuck in this universe?

It was a very rare occurrence, but Katari found herself regretting her decision to come with the Doctor.

The Doctor and Mickey appeared suddenly, both gleeful. There you are! You all right? No applause, I fixed it! Twenty-four hours, then we're flying back to reality." His grin faded as he saw Katari looking at her phone. "What is it?"

"My phone connected. There's this... Cybus Network, it finds your phone. It gave me Internet access." Katari stared at her phone as if that would explain everything.

"Katari, whatever it says, this is the wrong world." The Doctor shook his head at her.

"I don't exist."

"What do you mean?"

"There's no Katharina Ariel Malloy. I was never born. Neither was Rose. There's my Mom, and there's Pete and Jackie…they still married…but neither Rose nor I were born."

Katari knew it was wrong, but she desperately wanted to see him. Even if he wasn't her Pete, he was the only father she would ever see again. The Doctor tried to grab her phone, but she held it from him.

Katari was pleading with him now, and saw her chance when Mickey began to talk about seeing things himself.

"I'm sorry. I've gotta go." Katari shrugged at the Doctor, and headed in the direction of her father's home.

The catering outfit was uncomfortable, the house was hot from the crowd of people and her feet were killing her, but she was within feet of a man who reminded her of one of her favorite people. They had been chatting for a bit, about Jackie, and how he didn't have any children. She had thought maybe in this universe she just had a different name, but it didn't seem that way. Pete had started to talk about divorcing Jackie when he paused.

"Why am I telling you all of this? We haven't met before, have we?...I dunno, you just seem sort of –right…"

Katari had to restrain herself from smiling at him. Even in a parallel universe Pete was able to share things with his daughter. He had done that when she was little. Rambled on about things she couldn't understand, then smiled at her and asked her why he was telling a four year old or five year old these things.

The Doctor had called them Cybermen, saying that they were humans who had been stripped of emotions, all humanity removed. Now Mickey's parallel universe self was dead, and she and Pete were trying to save the human race of this other universe where she nor Rose existed.

A Cyberman had just asked Pete to confirm that he was Peter Tyler.

Katari silently watched him reply, "Confirmed."

"I recognize you. I went first. My name was Jacqueline Tyler." The Cyberman replied in a monotone voice.

The Cyberman tried to restrain them as they shouted in shock, but Pete shoved forward, "You're lying. You're not her! You're not my Jackie!"

Katari was close to tears watching this parallel version of her father panic at the loss of Jackie. She had always daydreamed that something evil had kept him away from her mother, and that he truly loved Marie Malloy and wanted to be with her. But if this Pete was anything like her Pete, she knew that her daydreams couldn't have be true.

Mickey was gone. Katari hadn't known him for very long, but she felt the emptiness that was left. She couldn't imagine what Rose was going to say when she discovered he had decided to stay in the other universe. Rose had started dating a man at Uni, and Katari was pretty sure that had assisted in Mickey's decision to remain there.

Pete was still in his world. Katari had thought about asking him to come back with them; maybe at the very least, Pete could be happy with Rose's Jackie. But she knew the Doctor would tell her that Pete needed to stay in his own world, that it would have been impossible for a new Pete to be with a woman who knew him as dead.

The TARDIS had surprised her with her favorite Crème Brule flavored hot chocolate. The TARDIS must have been saving it for such an occasion.

Now she sat, curled up on her reading chair, sipping the hot chocolate and rethinking her time with Pete.

"You okay?" The Doctor's voice startled her from her thoughts.

She smiled tiredly, "Yeah, I'm fine."

The Doctor entered her room cautiously, as if expecting the TARDIS to suddenly lurch him one direction or the other. "TARDIS made you hot chocolate?"

"Yeah, my favorite."

He nodded, looking as if he was going to continue but wasn't sure what else to say. "Do you have many memories of your father?"

Katari sipped at the hot chocolate and beckoned for the Doctor to sit next to her on the couch, "Sort of. I only saw him once a year, but he would stay for three or four days each time and spend every day taking me places and playing with me, buying me things, telling me stories. He didn't come that last year because Rose was going to be born soon. Mom tried to make it up to me, but I spent the whole week around my birthday pouting and crying and asking why he couldn't come. I don't remember much about how my mother told me about his death. I've probably blocked it all out. I just remember thinking the next year on my eighth birthday that he was going to be there, that he would be there. I don't think I really understood until then that he wasn't coming back ever again."

The Doctor rested his hand over her's, which was sitting on top of her thigh. "I'm sure he would have come back had he been able."

Katari smiled at him, "I know."

He rubbed his thumb lightly across the back of her hand, sending shivers up her spine, then lifted his hand and stood, "Enjoy your hot chocolate."

"I will, thanks." She resisted the urge to ask him to stay and enjoy a hot chocolate with her, maybe sit and talk until the early hours of the morning. The Doctor never seemed to want to do things like that, nothing that could be constituted as bonding. Instead she smiled at him, sipped the last of her hot chocolate and pulled out her pajamas as he slipped out her door.
