Tempus has slipped off when the baking was done, and took to exploring the halls of the TARDIS. It was like walking in familiar grounds and yet there was so much that was strange to the Doctor. He smoothly ran his hand along part of the wall before pulling it away, smiling to himself.
That's when he was sure he heard music... coming from a room down the hall. He made his way at a decent pace and stopped at the door, opening it before looking inside. And that's when he saw the cyberman. Why would one of their kind be on board? It didn't make sense. Of course, not all cybermen in this universe were a danger to people. Some had broken off to form their own society. As did the Borg... and few of the Daleks. But one on the TARDIS? This called for curiosity.
The Doctor walked inside and smiled, peering at the cyberman with fascination. "Hello... have we met?" he asked. "You can call me Tempus. I find it doesn't confuse people here as much if I use a name besides Doctor... And less people ask me what I'm a Doctor off..." he paused his rambling to let the other reply.
