AN: This is a work of fiction. I don't have any proof on the existence of parallel universes…. Yet.

AN 2: The flashbacks/dreams are written in Italics.

Please review.

Tony woke up with a gasp. He looked around to find himself behind his desk in the bullpen. He looked at the window and noticed the sun was barely beginning to rise. Sighing, he glanced at the clock on his computer screen. It was 6:40 in the morning. He decided to get up, since going back to sleep for less than a hour seemed useless to him.

Walking towards the gym's locker room to take a shower he found himself reminiscing the dream he just had; he didn't usually remember his dreams. Yes, sometimes waking up he still felt the "leftovers" of the dream, but they were usually just light feelings of joy, pain or fear; nothing really clear. This time, though, he could remember exactly what was the dream that caused his not-so-nice awakening. Mostly because it was more of a flashback that his sleeping mind caught from his memories and unconsciously brought back rather than a bare fragment of his imagination. Sitting down an uncomfortable chair in the middle of the locker room, he replayed his dream once again in his mind, this time fully conscious of the memory he was producing.

"Do you believe in parallel universes?"

"What do you mean? Is this some sort of movie reference?"

"Ha-ha, no Katie dear. I'm asking a serious question here."

"Well, Tony… I am not sure. I mean, it's not something I think about everyday, you know?"

"Sometimes I wonder if they exist."

"You will never cease to surprise me, DiNozzo."

"Well, you know the movie 'Sliding Doors'?"

"Here comes the movie reference…"

"You know the one with Gwyneth Paltrow…"

"Yes, I know the movie, Tony."

"Well, as the audience we get the chance to see what would have happened to her if she caught the train and what would have happened if she didn't. I think parallel universes are exactly like that. You know, places where we made different choices in life or well, where fate had different plans for us."

"For example?"

"Well, in the movie in one universe Gwyneth Paltrow's character dies and in the other she doesn't. You know that's a pretty big difference..."

"I guess it is... Mind to give me a more practical example?"

" Well, what about... Have you ever wondered how would have things turned out for you if you just went all the way through law school rather than joining the Secret Service?"

"I would probably have a family by now, work for an important firm and keep a few vintage Porsches in the garage."

"See, that's what I'm talking about, Kate. Maybe in a parallel universe you're married to a chubby and bald mediation lawyer and have 2 kids that look just like their father."

"Maybe you're a fat cashier at Walmart. That would be realistic."

"Oh, Kate, you hurt me!"

"That's what I was aiming to, DiNozzo. Anyway, I think the government pays us to work, not to wonder about parallel universes."

"I know Katie, but you can't deny that this is a pretty interesting subject."

"For once I might just have to agree with you."

"Hmm.. Kate Todd is agreeing with me. How did we even end up in a parallel universe so fast!? I want to go home!"

"Tony, you're such an idiot! I am serious. I like your idea about the existence of a parallel universe. If you're right it might mean that there's a place somewhere where all of our 'what ifs' have answers…"

"You know what, Kate? I will bring you to a parallel universe one day. So you will see for yourself that working with me is way better than being married to a chubby and unattractive workaholic."

"Tony, first of all what makes a universe parallel is the fact the it is PARALLEL and parallels are never meant to meet. Second of all I can only think of very, very few things that might be worst than working with you, and I am not even so sure about half of them."

"Give me an example…"

"Well… Being shot by a sniper in the head would probably be worst."

"Not bad, Katie, not bad. But I hope you'll take up on the offer."

"What offer?"

"Visiting a parallel universe with me, of course."

"Sure. But I advise you to finish your paperwork before traveling around galaxies. You never know how far Gibbs could go to track people down!"

"Ha-ha, Katie. You can almost be funny when you want to. So, getting shot in the head, huh?"

"Shut up, DiNozzo! That report won't write itself."

Tony sighed at the memory that his dream had brought up and at how ironic Kate words had been. Of course, back then neither of them could have imagined that only a few months later a very bullet was going to be shot right between the eyes of the ex Secret Service Agent.

As if to wash his thoughts away, Tony stepped into the shower and started whistling a tune. It had been 4 years since Kate's death, and even thought it had affected him deeply, he had moved on.

'Memories won't bring her back', he said to himself while pouring some shampoo into his hand.

Please, let me know what you think. If you notice any major grammatical mistake, let me know so I can fix it! Thanks.
