Retcon, rewrite, compromise, etc.
I honestly wouldn't be that disappointed if a headcanon of mine is debunked. I tend to expect it beforehand when roleplaying an ongoing series. I usually just adapt by rewriting it to fit the new lore. Either that or doing away with certain aspects of his story completely.
IE Max's Ala Mhigan background. If the story takes us there, there's a HUGE chance that a lot of his backstory could be invalidated (which is why I'm currently in the process of genericizing him, so his character is less likely to be rocked horrendously by future developments in the story)
