[The Dark Knight] How exactly does Batman disappear so quickly/efficiently from Gordon?
gpt
This one isn't so hard to answer. The key is progressive misdirection. You see, although it may seem Batman is absolutely gone, it's quite likely that he isn't more than a few feet/meters away. He'll wait for a nanosecond when the subject is lost in thought and use that moment to place himself outside of that person's range of perception. He isn't FAR outside, he's barely outside. As the person is startled and begins to look, Batman will distance himself more and more, as he knows where people tend to look first and foremost.

Remember, he is a ninja. Ninja were trained in infiltration and camouflage. It wasn't unheard of for a ninja to sneak into a castle during the day as a poor vendor, then slip into the pond and breathe through a straw for hours to come out at night. They could hold a fixed pose for hours in order to hide in shadows in plain sight.

Simply put: he knows where you'll look, when you'll look, and how long you'll look as soon as he disappears, and uses that to remain unseen as he makes his escape.
