I don't know the rules on Memory Alpha for creating pages, but well, here we allow pages for every noun that appears on a story. Is it really usefull to just turn our "references" section into a massive list of (seemingly) random nouns with no context?
I understand that references is for more "trivial" stuff, such as (using The Pilot as an example) "The TARDIS has a macaroon dispenser."
"Macaroon dispenser" is something that appears/is mentioned during the episode, so it warrants a page (and thus a link), but it's not really relevant to the plot, so it doesn't need to be on the plot section, differently from, say, "Heather points out a mysterious puddle on the concrete that ought not to be there, as it hasn't rained in a week", which is plot-relevant, so it does belongs on the "plot" section, rather than being put on "references".
