The time has come for Commander Tad Thatcher to look in the mirror. The time has come to ask himself...am I that kind of man?

In fact, they make it hard to avoid. I'm in the business of preserving the timeline - making sure the world sticks to the sacred rule of One Second per Second, and that history unfolds according to plan. The problem is, there is no plan until I make it.
