To be honest, I don't think they will. I just doubt that comments by Erica Messer from 2012 occurred to them when writing an episode for 2019, especially offhand comments like the one about JJ's father were. Also, "legitimate" is not the best term, apologies. I only realised that when I reread our conversation again. A better word would be "official". Sorry for that confusion.

As I said, I can't recall if the fate of JJ's father was mentioned on screen before but as far as I'm aware, this is the first time. So either they'd overlooked that detail when writing Sandy's character in Season 14, which is fair enough since it's almost eight years ago now, or they purposely changed it, which would make this a retcon.

Comments from a crew or cast member are perfectly fine for our purposes when there's no other source available. but what's actually said in the show during an episode overrules anything else. That's the way most wikias handle contradictions like this, which IMO is also the best way: information from the main medium in a franchise, in this case that would be the show, takes priority over all other sources, even ones from people involved in the production.
