Hello, and welcome to the final segment in my Changes trilogy. Please sit back and enjoy.

Katherine Reese was in her bedroom getting ready for her new job as the Prime Minister's personal assistant. She wasn't feeling great today, but she just passed it off as nerves. This was her first proper job, and she didn't want anything to go wrong. She had dressed as professionally as possible, and had made sure that everything was perfect for had this day.

The only trouble she had, other than feeling sick, was her Dalek. It hadn't stopped filling her mind with doubt and fear, saying Harold Saxon was not to be trusted, that she should stay as far away from him as she could. Katherine had tried her best to block out the voice of the Dalek, and had succeeded in pushing the voice down as much as she could. But she still heard it and all its doubts.

Katherine left her apartment and went to 10 Downing Street. She stood outside the door for a moment, took a deep breath, then walked inside.

Before she could really go in, she had to pass security. Her badge was shown, her bag was searched. She walked through the metal detector as her bag was scanned. The security guard nodded; she had passed. She picked up her bag and badge and went inside.

She was met by people running around trying to get everything ready for this morning's speech by the Prime Minister. Through all the craziness, she found Letisha Jones, one of her friends from Saxon's campaign team. "Tish!" she called out. Tish saw her, smiled, and ran over to her. "Katherine, how are you?" she asked as they hugged.

"Oh, you know, nervous as hell."

"I know the feeling." They both chuckled. "Oh, Mr. Saxon wanted to see you when you got here. Come on, I'll take you upstairs." They walked up to his office and Tish knocked on the door. "Yes, come in," a voice came from within. She opened the door, saying, "Sir, Katherine Reese is here."

Harold Saxon stood and smiled, walking over to the girls. "Ah, Ms. Reese. How have you been?"

"Wonderful, sir," she replied, shaking his hand and smiling.

"Excellent. Well, we're about ready for my lovely little speech. So you girls can go get tea, and bring me some as well, if you don't mind." He gave them one of his charming smiles as they nodded and left to get tea.

Katherine knew Tish was talking about her sister, worried that she hadn't heard from Martha in a long time, while they were getting tea, but Katherine wasn't paying close attention. She was worried; not because of the Dalek voice inside her, because she still hadn't heard from Jack. She had tried calling but he didn't answer. She hoped he had found The Doctor finally, but she still wanted him to call her. She was worried about him, and she missed him. She smiled as Tish picked up two tea cups and began to walk away. She got her tea cup and followed. They went back to the main office. "Thank you. You can go relax for a while until the speech." They nodded and left the office, going to their own desks.

When Katherine sat down, she continued to think, then picked up her desk phone, dialing Jack's mobile number. She listened to it ring and sighed once it went to voicemail. "Jack, it's Katherine. Please call me. So much has happened; I have to talk to you. Please." She hung up and leaned back in her chair, cupping her face in her hands. She couldn't get too emotional, though, as Tish came in saying it was time for Saxon's speech. They left Katherine's office together and went to watch the speech live.

"Britain, Britain, Britain. What extraordinary times we've had. Just a few years ago this world was so small. And then they came out of the unknown, falling from the skies. You've seen it happen. Big Ben, destroyed. The spaceship over London. All those ghosts and metal men. The Christmas Star, come to kill. Time and time again, and the government told you nothing. Well, not me. Not Harold Saxon. Because my purpose, here, today, is to tell you this. Citizens of Great Britain, I have been contacted. A message for humanity from beyond the stars." That's when everyone in the room saw a video of a metal ball floating in the air. As she watched, Katherine's stomach churned, and she heard her Dalek trying to figure out who this metal ball was. But as hard as it tried, it couldn't place the creature. Katherine and the Dalek focused again when Saxon began speaking.

"Ooh, sweet. And this species has identified itself. They're called Toclafane. And tomorrow morning they will appear, not in secret, but to all of you. Diplomatic relations with a new species will begin. Tomorrow, we take our place in the universe. Every man, woman, and child…"

Katherine didn't hear the rest. She excused herself and calmly walked out of the door. But once she was out of the office, she ran to the nearest toilet. Once she found the toilet, she leaned over the bowl and threw up. She continued to lean over the bowl, coughing, when she heard the door open. "Katherine? Are you all right?" Tish had come to see what was wrong.

"Yeah, I'm fine. Don't worry about me, I'll be out soon."

"Are you sure?"

"Yeah, I'm sure." She heard footsteps leaving the bathroom and the door closed. She sighed. What was wrong with her? She had been getting sick a lot recently, but she didn't feel sick or anything. She kept trying to figure out what was wrong with her, and then… "Oh my God."
