So there are all these theories about what actually happened with Mituna's accident. I've heard them, and read them, but has Andrew confirmed anything true? Or is he just doing it so we can come up with our own theories about what happened and remain curious?

Hussie has confirmed nothing. He probably never actually came up with the incident himself and probably never intends to show it. But it’s better that way. Some of the fan theories go super in detail and it’s pretty great.
