Crossing your own time line is something that most Time Lords frown upon. He seemed to have a disturbing tendency to run across himself though. Perhaps it was because of his travels that he found himself in the same place as himself so often. After all it did get hard to keep track of where he'd been after awhile.
Usually he would turn around and go the other way. It could be dangerous running into yourself, you never know what you might accidentally let slip. This time he found himself hiding behind the bookshelves in the shop watching himself and his companions. The girl was perfectly normal, as much as anyone could be normal, but the other one was different.
For one he didn't recognize the species at all. There weren't many races with an exoskeleton that were also bipedal in the universe. He couldn't help but feel a voyeuristic thrill as he watched them shop. The girl had been arguing with other one for the past few minutes and it looked like he'd given in to what ever she had been suggesting. His mouth fell open in astonishment as he watched the man blend into the bookcase behind him. The girl clapped her hands and stood up on her toes to give him a small kiss on the cheek. He closed his mouth with a snap and firmly grasped the handle of his umbrella.
He had no idea who this person was or how he'd meet him, but he was looking forward to it. Sometimes he feared that he would run out of things to see in his travels. Now though he knew he had at least one more surprised guaranteed to him and that was more then enough for now.
