Geez, all of this stuff with Luke-Snoke/meta-crisis Doctor just reminds me why I’ve never bothered with “expanded lore” (comics, novels, etc.), even back in the pre-Disney days. I’ll keep myself confined to the films and t.v. shows, thanks.
(Not knocking anyone who does prescribe to all of this supplemental material; just saying that it personally feels like a massive can of worms to me.)
