Something about theories we might need to consider

Though theories usually are and should be about events in game and evidence should be based on in-game events as well, there's probably one element missing and that's why we're overlooking everything.

Common sense also must come into play.

Not just that, but also facts that can be proven not in game, and common sense can play a big part. A theory just based on proven real world facts doesn't make it entirely false!
