Can you cite your sources for the production info (companion guides, TV guides, magazines, DVD features,...)? That's a thing many people look for when deciding if to merge or delete, because most non-plot non-fan sources automatically satisfy WP:N, WP:NOT#PLOT and WP:RS/[WP:V]]/WP:OR for fiction articles. The last two production points are weak and might count as trivia that can be removed. Still, I would no longer to merge your article version if brought back (since I said I'd only merge/redirect the clear cases), but someone else may try later (in a year, five years or ten). –  t•c
