Niggers, and their equivalents, are just the "shadow" of some actually evolved human in the world. In other words, they act the exact opposite to whichever "whitey" they're linked to, which is the source of the "shadow". The simplest example would be skin color. Is their whitey white as snow? If so, their "shadow nigger" will be darker than coal.
From here, we can generalize a bit. Is whitey rich as fuck (and in the grand scheme of things, whitey tends to be pretty rich considering the fact that most humanoids make less than 3 dollars an hour)? Their linked nigger, who could be all the way on the other side of the globe, will be a poor nigger. Is whitey a methhead good for nothing dirty KKKracker? The nigger now has a chance.
That nigger's linked whitey was simply too calm and collected for the nigger's own good, and thus, in a situation where his whitey equivalent would have handled things just fine, the nigger shadow felt compelled to chimp out
