The most significant issue in The Lord of the Rings: The Rings of Power since the show's first episode has been the identity of Sauron. We know that the future Dark Lord of the rings will shapeshift in the same time period as the Prime Video series, and Galadriel has been relentlessly on the lookout for him since the beginning of the show.
In the initial episodes, some interesting individuals have emerged (and some less) but it's time to examine a slightly more out-there approach.
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 that the answer?
Given the number of unknown people the show has thrust in our faces as potential Saurons, it may seem unlikely, but there is precedent for imbuing power into objects in this world (just see the title of the program).
Theo's arm is ruined, and the sword's hilt is extended to a full sword when it attaches itself to his, as explained repeatedly in the elves' fourth episode. This theory may be backed up by the fact that the sword is an object of fascination to Theo or other humans.
If the sword were Sauron, it might be that the sword itself placed Saurons power inside Theo, gradually retaliating with him to restore the Dark Lord. Or perhaps Theo will demonstrate that humans can fight 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.
But it was a good week for the Halbrand is Sauron crowd, as he continually delivers mysteriously veiled lines that suggest he knows more than he has admitted (and that he is attempting to manipulate Galadriel, something that became even more evident as he explained to the freaking Galadriel how to manipulate people).
Adar, the elven orc leader, had a large episode, revealing Arondir how much he doesnt know about the world while being charismatically menacing while doing so. We assume that he will work for Sauron, but you never know. If Galadriel needs to be taught how to assert her influence by a human many years her junior, anything is possible with this program.
