Severus & Edgar
It wasn't in his job description to analyse, so to speak. The Aurors did that. He was the guy sent out with a name to bring the culprit in, and once that was done he was out of the picture (or in a St. Mungo's bed, which equated to the same thing). It was easy to become cynical in his line of work and he had seen it many, many times in his colleagues. He saw people constantly living on edge, never relaxing, always on duty. Edgar simply wasn't wire that way.
But the question wasn't quite so simple as it seemed because analysing himself was an entirely different matter.
"What's that phrase? Actions speak louder than words?" he quipped after several long moments of silence. "Guess it's the Hit Wizard in me. Or the Gryffindor--take your pick." He paused, casting a glance in his direction. "I've come to find that people show their true nature in the end. No point worrying about hypotheticals."
He looked back to the event, taking a sip from his whiskey. "This doesn't strike me as your scene."
