The greatest mystery in The Lord of the Rings: The Rings of Power since the first episode has been Sauron's identity. We know that the future Dark Lord of the rings will evolve in the time period the Prime Video series will be set in, and Galadriel has been relentlessly on the lookout since the show began.
In the early episodes, some good candidates have emerged (and some are less successful), but it's time to revisit a somewhat more out-there theory.
What if Sauron is that messed-up sword?
Theo, a human child who is the son of Bronwyn, discovered a cursed blade in a barn a few episodes back, and has been fascinated by it ever since. Is there a way to know?
The notion of putting power into objects in this world may seem unlikely, considering how many unknown individuals the program has thrown in our faces as potential Saurons.
And that sword is really broken. Initially a broken hilt, it grows into a full sword when it attaches itself to Theo's arm. It's a toll, too, we can see the mark it has left on his arm, as demonstrated in the shows fourth episode). This theory might support Theo's or other humans' dislike of the sword.
Let's say the sword is Sauron, and in an effort to maintain his authority and relevancy while remaining safe from the hunters, he imbued himself into a cursed object. That could make Theo a simple servant of Sauron, gradually replacing the child with Sauron himself. Or perhaps Theo will demonstrate that humans can resist evil impulses, despite what the elves believe.
Checking in with the other Sauron candidates
If you're someone who's still betting on Sauron being the Stranger, this week's episode was a harfoot-less (and giant-less) episode, so there's no news there.
The Halbrand is Sauron crowd had a good week, as he continually delivers mysteriously veiled statements that suggest he knows more than he knows (and that he's trying to manipulate Galadriel, something that became even more clear as he explained to the freaking Galadrielhow to manipulate people).
Adar, an elven orc leader, had a major episode, explaining how little he knows about the world and making himself a charismatically menacing figure while doing so. This shows that anything is possible if Galadriel needs to be taught how to assert herself.
