That's the question that author Troy CLE initially tried to answer when he created his character, Louis Proof.
But it would be simplistic to paint Louis as simply a black version of the beloved Harry. Louis is a very different character. The brainchild of Troy, Louis loves listening to hip-hop, racing radio-controlled cars, and hanging out with his best friend, Brandon. If he sounds a little normal, maybe it's because he is meant to be.
