The TARDIS whirred, coming into existence on another street corner, miles from where it had just been. The Doctor ran out, towards a random place.

"Doctor!" Amy called out. "What is this?"

He turned and smiled. "This is Torchwood. If we're going to find the first person on our list, this is where we'll find him."

He ran up and knocked. The door opened and he stepped inside, followed by the Ponds.

"Hello," said the man in the front, a quizzical expression on his face. "Who are you?"

The Doctor smiled. "I'm the Doctor, and I'm looking for Captain Jack Harkness, please. Thanks, Ianto."

Ianto looked startled. "No, I've seen the Doctor. He doesn't look like you."

"Well," the Doctor said. "I'm the same man, with a different face. Didn't Jack tell you about me? I'm offended."

"Um, alright, just go on in there," he said, opening a door and gesturing the trio through.

They stepped into the next room. Rory and Amy looked around the room, staring at everything, but the Doctor didn't look anywhere but forward, walking straight to the back of the room. He ignored the eyes following him as he approached. Amy and Rory saw where he was headed, towards two people talking near the back.

The Doctor stopped right by them, and a grin spread across his face. "Hello, Jack," he said cheerily. The two people turned towards him. One, a woman with dark hair and pretty hazel eyes, looked openly confused. The other was a man. He had dark brown hair and bright blue eyes. He quickly appraised the Doctor, then a smile split across his face.

"Only one man I know would wear an outfit as ridiculous as that," he said, leaning back against the wall. "How are you, Doctor?"

The Doctor looked offended. "Ridiculous?"

Jack raised an eyebrow. "A bowtie? Really?"

The Doctor straighted his bowtie in his signature way, saying, "Bowties are cool." Jack just rolled his eyes before turning to the other two.

He looked at Amy first. His grin spread wider as he held out his hand. "Captain Jack Harkness."

"Married," the Doctor sighed.

"I was introducing myself!" Jack complained.

Amy laughed. "It's fine. I'm Amy."

Jack then turned to Rory. "Hi," he said. "Like I said, Capt-"

"Married to her."

Jack turned to glare at the Doctor. "What's the harm in saying hello?"

The Doctor shook his head. "For you, saying hello isn't just saying hello."

Rory cut in. "I'm Rory, by the way, in case anyone cares." Amy grabbed his hand.

"Oh, and, you remember Gwen, right?" Jack said, gesturing to the woman next to him. She gave him a smile.

"Of course!" the Doctor said, holding out his hand. Gwen took it, then stepped away saying she had something to work on.

"So, Doctor," Jack said, "why are you here? I kind of doubt you dropped by for a quick visit."

The Doctor shook his head. "No. I recieved this, just before coming here." He handed Jack the letter. Jack read it, recognition filling his features as he saw familiar descriptions.

"How are you going to get the last three?" he asked. "One will die if you bring her back, and two are a bit out of our reach."

With a shrug the Doctor took the letter back. "Who knows. I just think we had best be off. It would probably be a good idea to stop this before the black hole destroys everything."

"You think?" Amy asked sarcastically.

Jack grinned at her. "I like her," he said to the Doctor.

"You like everyone," the Doctor replied, heading towards the door. Jack turned to his crew after saying he'd meet them outside.

Amy, Rory, and the Doctor all stepped into the TARDIS to wait. Rory seemed to realize something.

"Doctor?" he asked.

"Hm?"

Rory looked unsure of how to approach the subject. "It said in the poem that Jack couldn't die. Does that mean that he actually can't, or-"

"No, that's it," said the Doctor. "It is physically impossible for him to die."

Amy and Rory exchanged a glance. "How?" she asked.

The Doctor waved a hand in their direction, fiddling with controls. "Long story. He died and an old friend revived him, he hasn't been able to die since, it's complicated."

"Just a bit," said Jack, stepping in. "So, are we going to the next one on the list?" he asked.

The Doctor looked up and grinned. "Of course. And you know who that is."

"Yep. And we might just kill two birds with one stone. Last I heard, he got married," Jack said with a smile.

The Doctor nodded. "You heard right. Here we come, Mickey Smith and Martha Jones!"
