That sad truth of the matter was Severus could use some happiness in his life, but he was certain he'd never have any. He simply wasn't worth the effort to anyone, and in the end, it was much easier to be powerful than it was to be happy.
There was some part of Severus that wanted to laugh at Locke. It was almost cute, the way he seemed so sure of himself and so sure that his trials and tribulations made him better than others. "You idiot," he snapped. "I never said I was any better than muggles, did I? I was simply pointing out we are different, and there is no way you can dispute that." He took a step closer to Locke, narrowing his eyes at him. "You have no idea the power I hold in my hands. A wave of the wand and two words and you would be dead where you stand. I'm not so certain anyone could or would do a damn thing to stop it in this place. I could be a God here... and I choose not to be." He took a deep breath. "Before you presume to know exactly what I think, perhaps you should take a look in the mirror and realize - you have no idea what I have been through or what I have done. Your past makes you no more special than mine makes me."
Severus was seething in anger, though most of it was misplaced. His anger was usually misplaced. He took a deep breath and broke eye contact with Locke. "Good day, sir," he growled, and with that he headed for the exit.
