You learn how to read a person, figure out what their ace in the hole is. Small fuzzy animals seemed like a good in. Possibly also ice cream, amusement parks, and flowers, but none of those were appropriate for the situation. And you don't really get that experience as an agent. Most of the people you encounter are trying to kill you in one way or another. You don't get to see any gratitude other than from the people you work with... and I was a solo operative for 10 years.
It's a little different, but our realities probably operate differently as well. Most of our aliens are a little too loud to stay secret. Unless you count Randolph, and that guy's just a prick.
Either? Both? It's complicated. My hands aren't anywhere near clean. But considering things actually were worse when I tried to do the right thing than any other time... I don't think I'm cut out for being anything more than the dubious entity with questionable motives.
