"S3 plot speculation, based on hours of thought, discussion, and analysis: -
Season opens on dark note, a surprise attack on the Elf camp by Sauron. Gil is held down by one orc and Elrond is knocked out by another orc throwing a shoe at him. Sauron questions Gil and demands to know where Galadriel is. Gil says she is far away and Sauron cannot get to her. Sauron explodes into a rage and starts whipping Gil with a branch.
- Gal finds Celeborn without even intending to but when he sees her he seems confused. He says something like 'Celeborn, that was what they used to call me....well, I'm Glorfindel' and Gal is like ???
- When Gal and Cel get back to the Elf camp Sauron has taken everyone except for Elrond, who is still unconscious. They wake him up and he tells them what happened so all of them go to confront Sauron. When they get to Sauron's fortress Gil is hanging upside down on a chain and he screams that 'it's a trap!'. Sauron is delighted to see Gal. Cel is angry hearing about the haladriel thing and he attacks Sauron and a massive brawl starts, the whole brawl is filmed in one take like a Cobra Kai finale.
- Sauron is winning and beating everyone at the same time using spinning kicks and flips, but then Galadriel throws her sword and cuts the chain Gil is hanging from and Gil falls directly on top of Sauron and knocks him out. Pharazon turns up late and says sorry for the delay and then takes Sauron into custody."
