An envelope is such an extraordinary thing. In the beginning of its short or long life, it is hardly given a second thought as it is hastily handled, being stuffed with whatever important or not so important message. However, as soon as it sealed it becomes a powerful object of possibility to whomever is on the receiving end. Within its walls can emerge bursts of friendship and joy or it can bear forth sorrows to bring the strongest to their knees. The caress of love can radiate from it. Whispers of secrets can be heard at times as it rustles in the exchange of hands. And before its seal is torn open by the recipient it has the ability to be all of that and more. So when a mysterious blue envelope popped into existence in the most impossible of places through a brilliant burst of golden light, one can imagine the surprise and shock that it brought to a young lady who was just trying to get through the day.

This particular young lady had just started work not a month earlier and this was her first shift completely on her own in the laboratory. The rest of the team were out in the field somewhere chasing the latest alien happening and she was left behind to do some of the more tedious tasks. A moment before the offending envelope so rudely appeared and started a chain reaction that would effectively alter all of time, 26 year old Lizzie Trembley was staring blankly at the computer screen in front of her. Her chin rested in her left hand as her right mechanically guided the mouse. Her face was framed by loose strands of dark hair that had somehow rebelled from the elastic that held the rest of her shoulder length hair in place. She was tasked with inputting research into the computer that had been compiled earlier. A boring task for even the most easily entertained. Her eyes had been keeping a steady eye on the clock as it slowly marched its way through time. She was still two hours away from the end and completely numb with boredom. It was the above mentioned flash of light that had pulled her from her stupor. Slowly she tilted her head around the monitor to look at what had just happened. It took a minute for her eyes to find the change in the room and pick out the blue envelope that now occupied the lab floor. It was after another solid minute of just staring at it with an open mouth before Lizzie's brain clicked into action and registered that she should do something.

"Okay, I know what to do…I know what to do…what the hell am I supposed to do?" she muttered desperately to herself. She walked slowly around her desk to the center of the laboratory where the blue envelope laid innocently on the floor. The air surrounding the envelope smelled like burnt atmosphere and the hairs on her body stood up, tingling with some unseen energy. As she drew closer she noticed that it was addressed to someone in a loopy script. She crouched down so that she could read the name. Her eyes widened as she read the name on. Her hand fumbled in her trouser pockets as she tried to pull her mobile out. Eventually she was able to tug it out and shakily scroll through her contacts before punching the green call button. She started to pace back and forth as the phone rang against her ear.

"Why are you never available when you're needed most? It's Lizzie and I have a situation here, please hurry back when you get this!" The lid of the mobile snapped shut as she pocketed it again. Her fingers found their way to her lips as she started to chew on her nails while she nervously continued pacing back and forth in the lab trying to figure out what to do next. Anyone who would know what to do next were gone on assignment.

"Get a grip Lizzie! This was bound to happen someday," she sternly scolded herself as she madly searched her brain over what the protocol was for this type of situation. "I was just hoping it wouldn't happen so soon," she mumbled as her mind came up blank. When she first started working for Torchwood, she knew that the strange and unexplainable was going to be a part of the job description. She would get thrilled just thinking about the possibilities of what she might discover while working for the organization. However, up until this moment it had always been more of an idea than reality. This was to be her first encounter among the wondrous impossibilities that seemed to be synonymous with the word Torchwood. She just had hoped that when it did finally happen, she wouldn't be alone.

"Think…think…think!" Her eyes frantically scanned her surroundings, taking in all the lab equipment. A silent ping went off inside her head as her gaze landed on the scanning equipment. Taking a breath she turned on the scanner and walked over to the envelope while she babbled to herself.

"It's just an envelope – nothing to be frightened over. Simply an envelope that appeared out of thin air." Crouching down with the scanning wand in hand, she waved it through the air inches above the envelope. Looking at the readout on the screen she forgot about how nervous she was and her eyes changed to confusion. "That's not possible."

"Look, I checked it out myself. Lizzie did not misinterpret the scan, that envelope is not from this universe."

A severe looking middle aged man was sitting across from a woman who in appearance could not be older than 24. The man was still dressed in the same clothing he wore when he received Lizzie's voicemail. When he called her back to find out what was going on, he immediately recalled the team and they hurried back, leaving no time to clean up. As soon as he made it back to Torchwood, he double checked Lizzie's findings before leaving his team to do some more testing and made his way to the Director's office. That was three hours ago. The legs of his trousers were caked in dried mud and his shirt was smattered with what could only be described as an array of dried alien sludge. His receding, peppered brown hair was cropped close to his head in general military fashion. He had a stern brow and a proud nose and if he was annoyed at having a superior who appeared to be half his age, he did not show it. The woman watched the man with some amusement, her clasped hands resting on the desk she was seated behind.

"It is not possible for an object from another universe to be here. All the cracks have been sealed and you know that, Tom," the Director stated with a thick cockney accent.

"You're right," he said exasperated. "However, I know what the readout said and no matter how impossible it seems that envelope has travelled across not only space and perhaps time, but also dimensions."

Tom knew it was going to be hard to convince Rose Tyler that this envelope was not of this universe. After all, it was common knowledge amongst Torchwood of how long and thorough she was in her search for such a crack that would lead her to another universe. He closely watched the woman as she herself was trying to figure out how to drive home the point of how impossible it all was. Her blonde hair fell below her shoulders in unruly curls framing her face. She wore less makeup than most women in their twenties, bringing forth the natural beauty of her features. She had thick dark eyebrows which gave her the appearance of having wolf eyes. She may have had the facade of a 24 year old woman but Tom knew better. The answer of her true age lay within her honey brown eyes. They were old eyes, deep with experiences and wisdom only gained with time. As well, Tom started at Torchwood twenty years ago and while time cruelly prodded and pulled at his body, she seemed to glide through with ease her body untouched and never aging.

Before Rose could disagree with Tom's statement and point out that the scanner might be malfunctioning, there was knock on her office door before it was swiftly opened by one of her assistants. "Here is the report they collected, Ms Tyler. As well, they sent you the recording to your tablet." The young man handed her the manila folder that contained all the data from every test that had since been ran on the envelope and what their ultimate conclusion was on its possible threat level. After all since the letter was addressed directly to Rose Tyler, their fearless director, they weren't going to take any chances – no matter how silly it is to think that a piece of post could be life threatening.

Rose grabbed her tablet and opened the video file that was sent to her. Tom stood up and rounded her desk to watch the recording over her shoulder. A black and white image filled the tablet screen, giving Rose and Tom the bird's eye view of the room. Rose watched with great interest as the silent scene unfolded before their eyes. Lizzie sitting behind the computer and in a brilliant flash of light an envelope appears in the center of the floor. She stopped the recording when Lizzie stood up to walk towards the envelope.

"Okay, let's just say for one moment I believe that this envelope had come from some other…place." She refused to say universe, because she was still extremely skeptical at best about the idea that this small piece of post had managed to do something she so desperately wanted to do for many years. "I'm dead in the only other," again she hesitated, "place that knows of my existence. Who would want to contact me or even know how to do it?"

Even as the question left her lips, she already knew the answer to her question. There was a deep confirmation in the gut of her stomach that desperately tried to give rise to excitement. She refused to acknowledge it though and discarded it as impossible. She knew the only person who had the capability to even gain the knowledge to send the envelope and address it to her thought she had already lived and died the life he wanted her to have, leaving a part of himself with her to grow old with.

She quickly flipped open the manila folder to scan the findings all of the diligent testing done by her team produced. However, before her eyes could glide over the data, they landed on the photo of the blue envelope with her name written across its face. It wasn't any color of blue. Her heart skipped a beat as recognition dawned in her eyes. No matter how long it had been, she would know that shade of blue. It was TARDIS blue! She abruptly stood up and half ran out of the room with Tom grabbing the folder and quickly following behind.

"Who do you think sent it?" Lizzie wondered out loud as the Torchwood team of agents stood looking at the envelope waiting for further instructions on how to proceed.

"Only one way to find out!" Before anyone could even move to stop her, Rose strode confidently into the lab and over to the envelope and crouched down. She paused as her fingers hovered over the paper. She could feel the energy radiating from the fibers of the paper as if it were alive and waiting for her. A moment of warmth came over her as her skin connected with it. Flipping over the envelope she found a small number 2 inscribed in white.

"What secrets do you hold?" she asked quietly as she stood up. The envelope felt heavy in her hands, weighted down by more than just paper within. Her excitement grew as she ripped open the envelope and slowly pulled the card from the blue encasing. Her fingers started to tremble a little over what possibility could be held within. While she didn't know what she was expecting, what she read before her on the card was definitely not it. Her eyes grew quizzical and she furrowed her brow as she tried to make sense of it. Coordinates and a date were scrawled across the card and nothing else. Her lips dipped into a frown as she flipped the card over. Written on the center of the back was one word.

Allons-y!

With each beat of her pounding heart, long dead hope and excitement grew inside her. She slowly turned the blue envelope upside down and emptied the remaining object into her hand. It was a flat, circular disc, slightly smaller than the palm of her hand, somewhat raised in the center. As soon as it touched her skin, it hummed to life with a red light blinking from the middle. Before Rose could even begin to try to comprehend what was happening, a small needle glided out from beneath the disc and pricked her skin. The light turned from red to green as a small robotic voice announced smoothly, "DNA match confirmed."

Rose's eyes widened and small gasp escaped her mouth as she had time to look up and make eye contact with Tom before the same brilliant golden light that birthed the envelope wrapped its tendrils around her, completely engulfing her body and blinking her from existence.
