Since Halbrand is Sauron, that disqualifies all other candidates!
The Stranger is not Sauron…he is, of course, Gandalf.
As if to clear up any remaining confusion, he literally declares, “I’m good!”

But when Gandalf attacks them, their skin is stripped away to reveal ethereal, white wraiths.
In any case, these monsters are banished or destroyed without much elaboration.

Hopefully the Stranger’s coming journey into the East alongside Nori will give us answers.
It only took the entire first season forThe Rings of Powerto live up to its name.
In any case, Celebrimbor is having trouble manipulating the mithril in his forge.
Though he still appears as Halbrand, the reflection in the water shows his true, armored Sauron form.
So Galadriel decides not to tell her friends any of this, a decision that can’t possibly backfire.
Instead, she encourages Celebrimbor to continue with the forging project that Sauron was so interested in.
This continues to be a baffling creative choice, and how long are they going to continue the ruse?
I have no idea how pretending this iconic character is dead helps anyone.
It’s a shame thatRings of Powerseason 1 is wrapping up just as things are getting interesting.
