 Why was the ugly man constantly chasing after Gabe?
Everyone in the room was aware of the big young man, and most of the humans present were resentful, for he handled himself consciously and arrogantly, as if his appearance alone were enough to make him superior to anyone. "You must allow me to pay your cleaning bill," Gabe said, taking out his wallet and extracting several credit notes without seeming to look at them. And that, coming on top of Gabriel Lockard's spectacular appearance, was too much. The ugly man picked up the drink the bartender had just set before him and started to hurl it, glass and all, into Lockard's handsome face.
