The thing about Heron is that he's always extrapolating meaning from the data he's constantly gathering, putting together the 2 & 2 that most people don't bother to even look for, let alone sum... trying to put together the entire universe like it's a puzzle. His deductions are always well-reasoned, and often accurate, though they're never flattering. He assumes the worst of everything and everyone around him. Unless there's very concrete evidence, the unpleasant explanation wins over the innocent one every time. 😔 silly boy. No light in his world.
