My first Doctor Who fanfic! I'm a huge fan, and I know that a lot of people have attempted to do an eleventh doctor-Rose reunion, but I'm going to try to put my own spin on it. The prologue may be inaccurate on some levels, considering that I don't look through four meter telescopes every day, but I did my best. Review, please, and enjoy!

Prologue:

Lily Harris sighed.

It had been a long, long day. A long, long night, that is. She'd been observing Europa through the 4-meter telescope since sunset—seven p.m. She checked her watch. Five oh nine, and the image was already starting to get bleary. When had she last slept? Was it thirty hours ago? Forty? Ugh…

Just until sunrise. Lily encouraged herself, trying her best not to let her heavy lids blink. Thirty minutes. The sky is already getting bright. Just until sunrise…

Europa was a very interesting moon—the most interesting moon in the Solar System in her opinion. All that ice, so smooth… it was just so… cool.

She was studying the crater that had blemished the ice. It seemed recent, which was what bothered her; where was the crater itself? It couldn't have vanished so quickly. And the shape of it was odd too… almost rectangular. Lily had a feeling that something out of the ordinary had made that crater, and her curiosity got the better of her.

She leaned into the lens, examining the details. Abruptly, a flash of blue interrupted the ice. Lily frowned, bewildered. She looked again, searching for the source… what was that? She looked closer, not believing her own eyes. No, that was definitely a blue box. It looked tiny, through her lens. Intrigued, Lily slipped in a more powerful one. Were those windows, on the sides? No, it couldn't be… She placed in an even more powerful lens. Yes! Yes it had to be! It had the words Police Public Call Box scrawled across the front in yellow. What on earth? No, what on Europa. Didn't they use to have those in the sixties? What the hell was one doing…?

Incredulous, Lily screwed out the lens and examined it. No, there was nothing painted there. Nothing could be wrong with the telescope—it was brand new! Finished today!

Tremulously, Lily screwed back in the most powerful lens she could find. Yes… it was a police public call box right on the moon… she had to tell someone! Who? Who would believe her?

Just as Lily was about to reach for her phone, something flickered to life on the police box. Lily squinted, not believing her eyes, as a figure stepped out… out of the police box… onto the surface of Europa… oh my gosh!

He wore no helmet, no suit. Just normal clothes. Well, not normal exactly—a bowtie and suspenders could never be called "normal". A million thoughts reeled through Lily's mind. Oh no, I'm hallucinating. Have I been drinking? I should rally tell someone… who will believe me? Wait a minute, it he… is he waving? At… at me?
