The Doctor thought he had closed all of the cracks in time and space then he remembered something. Just before he regenerated this last time, he found Captain Jack Harkness sitting alone in a bar getting drunk. He sent his friend that stupid not telling jack Midshipman Alonso Frame's name and walked away. "Why would I do that?" he asked himself now.

Amy and Rory were in their room. They had just finished helping the Queen with a minor crisis. He had some time to himself as he had the TARDIS go through Jack's history. When he got to 2009 and the attack on Earth's children by the 456, he stopped. "That shouldn't have happened," he said as his brow furrowed. "They were destroyed well before the Time War. The Time Lords and the Shadow Proclamation had them eradicated when they learned what the children were used for."

He saw the footage from Thames House and sighed. "I'm such an idiot. That last regeneration could be rude and tactless but that was cold, even for me. There has to be another crack rewriting history."

"What?" he heard Amy asked as he turned to see the newlyweds.

"I just discovered that we have one more crack to close," The Doctor said as he spun back around to the controls and saw where the crack was located. We're going to Cardiff."

"Cardiff?" Rory asked as he and Amy approached the console.

"Yes, Cardiff. There's a rift in time and space there. I thought it was an ordinary rift but it is the biggest of the cracks that took Amy's parents."

"How do we close it?" Amy asked as she squeezed Rory's hand a little. They both now remembered what happened with the Pandoricom.

"Quite simple really," The Doctor grinned.

"Why don't I believe that?"

He just glared at her as he maneuvered the TARDIS. "Here we are. Cardiff. Not long after I dropped off Jack."

They stepped out of the TARDIS onto a roof. They saw an SUV stop as the rift opened. He saw Gwen Copper drag a man toward the rift. He had known when he saw her on the TARDIS monitor with Rose that she was a descendent of poor Gwyneth's family. He also knew she was the one who had to seal the rift, just has her ancestor had done. He ran over to the others.

"You have to go, Gwen," he said as they all looked at him.

"Who are you?" Tosh asked.

"I'm The Doctor," he grinned as a convertible pulled up and Jack jumped out of the driver's seat. "Jack stop!"

Jack stopped short when he looked over and saw this stranger then he saw the TARDIS. "Doctor? But I just left you,"

"Wibbly Wobbly. Jack, Gwen has to go into the rift and she has to take the man with the bomb on his chest with her."

"She'll die!"

"I know, and I'm sorry but it's the only way to save the planet not to mention Ianto and your grandson."

Jack just stood there.

"Ten seconds!" shouted Ianto.

Jack looked from The Doctor to Ianto to Gwen. "I'm sorry Gwen. You have to go."

"But Jack, I love you!" she shouted.

"You should be in love with Rhys," he said softly as he went up to her and John. He put his hands on their chests, looked at John and said, "I'm sorry," and gave them a soft shove.

Gwen shouted his name as she fell into the rift and the bomb went off. The rift sealed and day turned into night.

"What just happened?" Owen asked.

"The rift sealed itself," The Doctor said as Amy and Rory joined him.

"And time has reversed to just after John came through," Jack sighed. "We have to avoid ourselves until tomorrow."

"But we could save Gwen," Tosh argued. "If time has reversed, we can keep ourselves from falling for John's ploy and…"

"We can't Tosh," Ianto said as he slipped his stopwatch into his pocket. "It will cause a paradox."

"What about Rhys?" Owen asked.

"I don't know," Jack said. "Owen, take the car and find us a hotel to stay in for the night, the fancier the better. We could us some pampering right now. Tosh go with him. Ianto, we need to hide the SUV then we need to talk to the Doctor."

He turned to the Time Lord. "You need to move the TARDIS. Send one of them to tell me where you are. I know there are things you can't tell me but you better have a damn good explanation for why I just pushed one of my people to her death and how you know about my grandson."

He looked at his team. "We better move. The others will be here soon."

Owen just nodded as he and Tosh went to the convertible while Ianto followed Jack to the SUV. Once they were driving Ianto spoke. "Are you going to go with him?"

"No," Jack said quickly. He reached over and took the younger man's hand. "I told you I came back for you. I meant that."

"A second later you said you came back for all of us."

Jack sighed. "Yes I did. I was gone for a long time, Ianto, a year. I need to tell you some of it so I can come to terms with it. But know this and never doubt it, you were my focus during that time. Finding my way back to you was the only thing that kept me sane."

Ianto nodded. "Will you tell me about your grandson?"

Jack nodded and they lapsed into silence. They found a place to hide the SUV then met up with Tosh and Owen at the hotel. Owen had gotten them the best suite in the hotel. He and Tosh sat on the couch in the sitting area and watched as Jack practically collapsed into an arm chair as Ianto hung up the great coat before finding a seat for himself.

"So that was The Doctor?" Owen asked. "The one you took off with?"

"Not exactly," Jack sighed.

"What does that mean?"

"This is a new regeneration. I don't know how long it's been for him since he left me."

Ianto got up to answer the knock on the door. Rory was standing there. "The Doctor is on the roof. He wasn't sure if Jack would want everyone to hear what he has to say."

"Tell him to come down," Jack said from his chair. "They deserve an explanation too."

"I need a drink," Owen said as he got up and limped to the bar. He poured himself a drink, looked at Tosh, poured her one and returned to the couch.
