Canon Disputes Are Serious Business

To an outsider, an argument over whether a piece of media is ‘canon’ looks like fighting over nothing. To the people having it, it's a genuine methodological dispute—about evidence, about authorial intent, about which sources count as primary. It's not that different from a historian arguing over which manuscript is more reliable.

This is why the correction lands with real weight when someone gets a detail wrong. It's not pedantry for its own sake. A constructed world only holds together if its internal rules are respected, and a misremembered detail is a small tear in something that was built, carefully, to be whole.

Headcanon—the personal, unofficial version someone builds to fill a gap the source material left open—deserves its own respect too. It's not a failure to accept the ‘real’ story. It's an act of authorship, applied to a world someone cared enough about to keep building.
