I think the Meteor Man leads the Harfoots to the Shire. I also think they are showing us the creation of Mordor at the South Lands. I was thinking that Halbrand was the reverse of Aragorn by failing his kingdom seeing as how it becomes Mordor. Also about Hal,
Apparently a leak came out and said that he's Sauron which would explain the character
In total, I think we're getting the creation of rings, creation of the shire, and creation of Mordor.
While watching the episode, I seriously thought Adar was going to be Sauron. Still possibly could be, but I doubt it. I really do think that Halbrand is going to be evil, and it isn't obvious. However, the fact he really got, dare I say, Obsessed about blacksmithing, and how incredibly powerful he was fighting off those guys. He was breaking bones a bit easier than I'd expect. I was thinking he was an Aragorn type, but man, he was brutal. He's also pretty wise politically, better than Galadriel is.
