"I'll tell you something funny. If you knocked this wall down, the crack would stay put." Rose sat bolt up. She checked the clock. 2:37 AM. "'Cause the crack isn't in the wall." She looked around. She noticed something funny, something that hadn't been there the night before. A crack. A crack in the wall. She could hear two voices through that wall, coming from, well, it seemed it was coming from the crack. Rose got up out of her bed. One of the voices sounded muffled, like it was farther away than the first. The first voice sounded strangely familiar, and yet, she was sure she had never seen it before. "Where is it then?" She could just make out. "Everywhere," Came the first voice, " In everything. It's a split in the skin of the world. Two parts of space and time that should never have touched, pressed together...right here in the wall of your bedroom. Sometimes, can you hear…" Rose pressed her ear against the crack. "Sounds? Yes." The second voice said. "Hello?" Rose said. No reply. Then she heard something press up against the wall. "Hello?" She repeated. "Hello?" She heard the first voice say. "Um, hello. Who are you?" "I'm the Doctor." Rose gasped. It had been a long time since she had seen her half-human Doctor. Even longer since she had seen the Time-Lord Doctor. "Where are you? How long have you had this crack here? Wherever you are." Rose stared at the crack. "Hello? Still there?" Rose found her voice, somehow. "Uh, yes. It just appeared tonight. It's never been here before."

"Are you sure?" The Doctor said.

"Positive." Rose replied, her voice cracking.

"Are you alright? Who are you?" Rose took deep breaths. She missed him so much. Her Doctor and her other Doctor. "I'm- I'm-" She couldn't do it. She couldn't tell him. "Yes?" He asked. She couldn't contain it. "Doctor! It's me, it's Rose!" Silence. "Doctor?"

"But- But how? I just left you. With my clone! How can you be talking to me? It hasn't even been a week since I saw you! How?!" Rose smiled slightly. She loved it when he got like this, but this was serious. "It's only been a week for you? Well, it's been much, much longer for me."

"How much longer?" Rose was silent. This was the hard part. "Um, well…"

"Rose, how long has it been?" He asked, his voice deadly serious. She tried to change the subject. "Why do you sound different?"

"I regenerated. Now how long has it been?!" Rose swallowed. "'Bout… 300 years."
