I tried with a different take on it to see how it would work, in where I had the prologue cut before Galadriel and her companions enter Morgoth/Sauron’s old leir, and then her waking up on the ship to Numènor. It kind of worked, up until I realized that most of her character development came from the first episode, and then it kinda goes into a stall.

Therefore, I reverted back to my linear structure.

The Harfoots don’t show up before the meteor crashes, the Southlands is introduced after Galadriel and Elrond’s conversation ends on “I want to hear more about your heroic tale” (or something of that ilk), and then intercutting the story threads up until a Act I climax when the Galadriel jumps into the ocean, the meteor crashes and the “Elf guy” is reunited with his old friends in the Orc Camp/Caves.
