River Song

There wasn't much to go on. Just a frantic, white hot note on his psychic paper with coordinates, a specific time and date, and the words We need you! There were very few people who could get his attention this way and the term 'we' seemed to suggest more then one person required his assistance. Whatever it was, it was definitely urgent. The red ink had been practically burning through his jacket pocket from the moment the message arrived.

The coordinates would lead him to a desolate looking planet which appeared to be mostly desert with a few scattered ancient looking ruins. There shouldn't be any life here, not in the current time period he'd been given and yet there were tents set up and other futuristic looking technology littering the sand covered ground.

If that weren't enough, it looked as though a whole wide range of alien ships had decided to hover in the sky, so many that it practically blocked out the twin suns of this planet.

River Song was there, armed to the teeth and looking decidedly more plump then the last time he'd laid eyes on him. She had a small group of young college aged looking students behind her.

"Get in! Get in!" She practically knocked him over in her urgency to get inside the TARDIS, ushering the students in behind her. "We'll be safe here. Everyone get in and find a place to sit down for now."

Oh and close up? She looked heavily pregnant. Congrats....
