I know that you're so exicted to expanding the wiki. But, you dont quite understand about the real intention of tv series wikia.
Let's take an example from Big Bang Theory or Shameless wikia, two wiki that i've been working as staff and ex staff. The admin mostly courage all the contributor to expanding an article about director,writer,and production staff .But, they still have a boundary due to wikia policy; by not listing and create all page about staff that been handling about Costume, decoration, art, music, and the other similar role.
Sounds De javu, but there's is a reason why the old admin doesn't handle this kind of stuff.
Think you could just merge this two page [[[Smyth|1]]] and [[[Buttler|2]]] into one page called "Unseen Detective/Police Officer", like your idea with the references page. From that point, you could listen all the mentioned only detective/police officer.
No offence, but making all the mentioned as a separarated page is kinda useless. Unless they have backstory with main characters.And all of them didn't even have an proper explanation and history; and only serves as one line articles.
I've seen that you been added several new location. While i support you hardwork, please only create a locations that related into the main/minor characters who appear at least 2-3 episode. There's a reasons why the old admin doesn't add every single location that appear on Brooklyn Nine-Nine
