Rose smiled in spite of herself. The Doctor always knew how to make her feel amazing, like the littlest things she did changed the entire world, and made his long life better.

"I don' remember Donna," she confessed, but something didn't add up. Another Companion, a hand-born Doctor- all of that couldn't have happened in just a few months. The Doctor had been in the house very recently, and hadn't mentioned a thing! Think, Rose, think...

Her eyes widened with revelation. "It ain't the wrong time line at all," Rose proclaimed, snapping her fingers. The Companion had figured it out. "I'm jus' too early!" She wasn't from an alternate universe. She had still been working for Torchwood in Pete's World. She had still lived as the mysterious Vitex heiress in a mansion, pulled from Powell Estate and existing right where The Doctor had left her. She had still been building the Dimension Cannon. If the project had been seen through, she would have found The TARDIS again, just like the man in front of her was saying. Instead, she was trapped here, waiting to go home and finish her story.

Rose Tyler was standing in front of her future.
