Black Hat encounters a person who is wearing not one, but two black hats. Black Hat is not a person to be trifled with, but from his reaction, he apparently believes that Two Black Hats represents a considerable danger to him. Black Hat knows how dangerous he is to those with one fewer black hat than him, so he continues the logic and realises that one who has one more black hat must be proportionally dangerous to him.
If a black hat is assumed to be akin to a badge of rank, then Two Black Hats certainly is superior to him in the capacity and willingness to do evil. Alternatively, and even more worrying, Two Black Hats could be someone who has the desire and the ability to acquire black hats (possibly killing the previous owners in the process if having two black hats really means that the individual is more malevolent than Black Hat), which he then wears like a badge of honor. With all this in mind, Black Hat edges away, keeping Two Black Hats in sight at all times. This movement and the accompanying line could also be interpreted as Black Hat being physically pushed away, like two negative or two positive poles of a magnet, although this does not explain why it only starts after a beat panel.
This comic is also a metatextual joke about xkcd itself. Because of the comic's simplistic art style and characterization, Black Hat has only two defining physical traits: his hat and his hair, which we see when he takes off his hat, and one defining personality trait, his malevolence. Randall then implies that the two traits must be correlated, so that a black hat signifies malevolence, and accordingly two hats must signify even more malevolence -- an idea that wouldn't make any sense in real life, where a person with two hats would just be making an odd fashion choice.

The title text is simply "..." This may represent the slow-motion pause during which Black Hat's nefarious life flashes before his eyes, as he considers his impending doom. It may also emphasize how the usually witty Black Hat is, for once, speechless. Or the title text is similar to that in 412: Startled , where Black Hat also becomes the little one (and with much focus on the black hat, as in this comic). As mentioned there, such a short title text could be due to the fact that it's a somewhat surreal comic, and any further commentary might have detrimentally brought it down to Earth. See also 82: Frame , with the same title text, but no relation to black hats.
Two Black Hats makes a reappearance in 826: Guest Week: Zach Weiner (SMBC) , down by the restrooms.
