They/Them
Even if they hadn’t introduced them early on we’d still have to go through everything that’s been seen. It’s a weak point of the show but still needed in order to move the story onwards. Best they do it now and get it out the way.But how are they going to show Sauron create Mordor or Elendil creating Gondor if not fast forwarding at points later on. Definitely they should’ve not introduced these humans so early on.
