A Watchdog comes to the site of temporal meddling, with their appearance being the warning to cease. Few, if any, do, so in the creature's observations, they begin calculating the next instance of meddling, and then the next, and the next - however many they can see into the future, and the likelihood of their occurring. At a certain point, often determined by the Watchdog, they will strike, and a common behavior found amongst them is that they deeply enjoy when they do. All of this is inevitable, and their patience is tempered only by their excitement.
