Author's Notes/Disclaimer: I, of course, did not create these characters, nor most of the dialogue and actions contained here. I had to watch it over and over to get it right - (oh, the agony! LOL) - so! Anyway - this is the follow up to the Torchwood Four story I wrote. Now we get to the meat of the how and why. Enjoy and rate! (PS - I wish I had thought of this - but I did think of the way to tie it in really good - I think...)

Jack pushed open the door to the long-long forgotten building. The site that greeted him and Toshiko was one they had encountered before- typical abandoned dance-hall turned dance club. Posters and graffiti covered what were once elegantly painted walls. Jack also took stock of the plastic covered furniture.

"The Ritz Dancehall. It's been derelict since 1989 but someone's complained about hearing music…" Tosh brought Jack up to date on the situation.

Jack started up the stairs, but stopped, thinking he heard something.

"…music from the 1940's."

Jack shushed her, looking up the stairs and tilting his head slightly, sure he had heard something, then deciding that they needed to investigate further. "You coming up?"

Not waiting for Toshiko, he started up the stairs. He could hear the sound of her heels behind him. Good ole Tosh, always one to follow the leader.

Jack flung the door at the top of the stairs open. "Wow! Look at the chandelier. No neon lights back then."

Toshiko was then swept into the arms of the man that she knew as boss. He did a few graceful turns with her as he finished his soliloquy. "Just dashing young soldiers and pretty young ladies. And as they danced, the girls would look playfully into their partners' eyes, smile softly, and say…"

Tosh stumbled on one last turn. "Jack, mind my laptop," she scolded.

Chuckling, Jack extended his arms and replied, "I was thinking more along the lines of – How long before you head off to war?"

Tosh smiled up at him as he placed a hand on her back to guide her down the stairs. She was fiddling with one of favorite devices – one that measured time and dimension, Jack figured. Not wanting her to fall down the stairs as she did so, he guided her ever-so-gently. The next landing down was more of the same to be seen.

"Come on. There's nothing here but memories and dust." Jack stood, waiting for Toshiko to finish punching buttons.

It was then that he heard the music. No way. I haven't heard that tune in so long. I don't know any modern band that plays it so well. Not here in Cardiff, at least…and the laughing – there is no way that can be a recording!

Jack was sure his ears were playing tricks on him. Wouldn't have been the first time. Then he noticed Tosh had stopped punching buttons and was looking up the stairs as well. With a quick knowing glance, they headed up the stairs together.

What they saw at the top was such a sight that Jack almost dropped to his knees and cried.

The entire top floor looked as though someone was throwing a party. There were groups of people standing around talking while others danced to the band they had first heard on the stairs.

Toshiko broke the silence. "They look so real."

Jack looked up from his wristband, which he was fiddling with out of habit and answered, his eyes wandering around the room. "They're not ghosts. It's a simple temporal shift." His eye caught one particular woman – a woman with dark hair who was wearing a red dress. A woman so like one from his past that he was forced to laugh out loud as he watched her cross to talk to a handsome man in uniform at a nearby table. "And it's beautiful!"

Tosh was suddenly scared and pulled at Jack's coat. "We should get out."

Jack nodded slowly and followed as Tosh turned back to the stairs. On their way down, Jack saw the same woman in the red dress, this time her arm was linked with a different man in uniform. He watched them as they went past, still haunted by the thought that he should know her. Had he been here before? No, he was sure of that. Her he would have remembered – he was dead sure of that.

Toshiko was now outside, having pushed past the man that was holding the door open for her. "Do call again," he said after them.

Jack turned back with a longing look and answered, "I would love to…"

The man closed the door after them, smiling an odd smile.

Jack looked at his vortex manipulator before looking back up at the sky. They had not noticed it was nighttime until this very moment. Toshiko was looking around bewildered for the vehicle they had driven there.

"Where's the SUV? Has it been stolen?"

Jack had his back to Toshiko when he noticed the poster announcing the dance. A dance for the troops. A dance for the troops here. Here in 1941. His throat was suddenly dry and his arm was poised in mid-air as he forced the answer out. "No, we have."

Tosh tried her cell phone in vain as the words were leaving his mouth. There was no way in the world that she wanted to be stuck here – even if it was with Captain Jack Harkness. She had things she was planning on doing, and none of them revolved around being stuck in 1941.

"It's no use," she sighed at last. "It's dead. I can't get through to the Hub."

Jack found himself wanting the Doctor once again. One use of his Sonic Screwdriver and all that would be fixed. Not to mention that he could get them back to their own time – or at least give it a good shot. "Let's go back inside. That's where we were when we crossed."

The two walked back in, an action that did not go unnoticed by the strange old man trying desperately to blend in with the crowd but failing miserably. They walked to a nearby marble pillar to observe the room.

"We really are in 1941. What if we can't get back?" Tosh sounded more than a little worried.

"Flotsam and jetsam slips through all the time. We'll get back." There was that woman again. Why was she so appealing to Jack? He watched her move through the crowd again, the same soldier as before linked arm-in-arm with her. There was something hauntingly familiar to him, and he had to tear his eyes away from her to continue. "Look on the bright side. Gives you one hell of an excuse not to go to your party." His eye caught her again.

Tosh realized he was looking at the woman and became angry. Why did he always have to be looking for his next conquest? She snapped him back to reality. "I have a life there! And they can't help us because I have the latest readings in here." She patted her ever-present laptop bag. "People are staring at us…"

"We need to try to blend in," Jack suggested, pulling his com from his ear and placing it in his pocket before helping Tosh take her jacket off.

She was feeling a little better until she took a good look around. "It's easy for you to say. I'm the only Asian here."

Jack looped her coat over his arm and an arm around her waist. "Don't worry. You're with the Captain."
