"Hey, Jack." he said. "Come meet an old 'friend', an alien part of the Klailath race. They take advantage of powerful people in time by taking over their bodied and rewritting history. They then feed off the time energy of newly made time." he explained. "You know us so well, Doctor. Now why don't we know about you?" he asked, approaching the Doctor and narrowing it's eyes. "Maybe it's because we haven't fought a lot in the past...? Oh, what do I know, I'm just throwing out ideas, here." he said, a bit cheerily for some reason. "And no worries, Jack. They never actually have ever harmed anyone on purpose, they just rewrite time." he turned back to the alien in the king's body. "You know we're going to have to stop you, right?" he asked the alien. It laughed a bellowed laugh. "What could you do? All you have is your companion and your screwdriver!" it laughed out.
