After a chase between Galadriel (Morfydd Clark) and Adar leaves at the mercy of the corrupted house elf, Halbrand makes it personal. For reasons unknown to the audience, Halbrand wants to kill Adar and asks the orc leader if he misses him. Adar, who claims he defeated Sauron, has no idea who Halbrand is. And in typical villain style, Adar teases Halbrand about potentially killing a loved one. But that’s as far as the footage. Galadriel prevents Halbrand from killing a person with any information of what is to come to the Southlands, or what has come, that is.
Up to this point, “The Rings of Power” has been very purposeful with any teasing or subtle nods, to source material or otherwise. It’s safe to assume the same for Halbrand, who has been kept as a mystery character since his debut on the show. He was crowned King of the Southlands shortly after the battle in the latest episode, but there was still a sense of false hope that lingered through the proceedings. While he may not be Sauron, his past and very near future could lead him to the dark side.
