Just to be sure, I checked some of the names from "Nameless" that Renard downloaded on his computer to make sure Harold Gunther wasn't one of those. To save you all some time, it's not one of the names, so it seems he really was a total stranger.

It definitely seemed to me at the time that Renard was becoming possessed or experiencing some sort of déjà vu, but re-watching it again, Renard seemed to watch Harold Gunther flip through his wallet multiple times, almost like he was reliving that specific moment... which of course is similar to how Renard has dreamed of the moment he was shot multiple times. Whatever happened to him seems very likely to be another side effect.

I think you're on to something, Lurkenfrau, with the "dark side" theory. Perhaps he now is vulnerable to having moments where he literally loses himself and all conscious awareness and is taken over by that "dark side", stuck in a senseless state of being, prone to doing evil.
