Next chapter! Sorry to keep ya'll at a cliffhanger like that!!! PS—There will be some Jack/Donna/Jenny.

The Doctor confronted Rose the next morning to see her old again, and barely able to walk.

"Where am I?" Rose asked.

"Oh, you're living in an alien palace for now while we try to find who killed the extra terrestrial leader," the Doctor blankly said. It couldn't have been his Rose last night. Probably a shift-shaping alien that takes the form of your loved memories.

They all had eggs and bacon for breakfast, then the Doctor and Jack began their investigation.

"None of the clues add up. No one's on this planet, except for everyone in this castle…" the Doctor puzzled.

"Doctor, are you sure it was Rose?" Jack asked. "Your emotions could have been toying with what you really saw."

"No! I was right, it was Rose," the Doctor replied through gritted teeth. "The leader saw her. It wasn't just me."

"Do you think, after she lost her alien part, and you know… the side effect was her old self retaliating on herself, like a Dr. Jekyll/Mr. Hyde kind of deal?" Jack suggested.

"I was thinking just that," the Doctor muttered. "But it couldn't have been Rose! Rose isn't like that!"

"Doctor," Jack put his hand on the Doctor's shoulder to keep his anger down. "She's human."

"Well, so how do we cure it?" the Doctor asked Jack.

"I don't think we know how to… but I know someone that can," Jack said. He patted the Doctor on the shoulder then ran upstairs to his sleeping quarters.

"Katie?" he asked his daughter, who was in his bedroom, on his portable computer. She was on Facebook. (She really is on Facebook, look under "Katie Harkness".)

"Hon, do you have the book the Doctor gave you?" Jack asked.

Katie, not taking her eyes off of the screen, reached into her jacket pocket and pulled out the worn book. As Jack was leaving the room, Katie spoke. "Oh, and dad?"

"What is it?" Jack asked.

"Did you love Donna more than mom?" she asked, quietly, still not looking at him in the eye. "I read about how you tried to save Donna. And I just thought, if you would do that for her, and not for mom… just saying, she still regenerated and all, but… plus, I technically have half-brothers. But, did you?"

Jack looked at his daughter, and said, "Katie. I loved your mother more than anything in the world. Well, I was drunk when I met her, but after I recovered from my hangover, we got to talk and that's why we had you. Then, when I learned I had a kid, I ran away. I just couldn't take it. I haven't seen your mother in thirteen years. But before I saw you, I met Donna. And sometimes, Katie. You just have to move on." He kissed his daughter on the head and left the room.

Jack ran downstairs and tossed the book to the Doctor. "Read," he ordered. "Trust me, Doctor. You'll learn more than you need to. Read it to her, Doctor."

Aw… :D Next chapter will have a lot of Rose/Ten, though I DO want to make something clear—I am not a screaming "Ohmigod, lyk, Rose/Ten 4eva!" type of girl, I just like the drama that goes along w/ it. Please REVIEW!!!
