The Rings of Power flips the “young boy finds an all-powerful sword and it helps him become a powerful king or warrior” trope upside down with Theo and his dark sword hilt. After an orc attacks Theo (hey, even orcs need to eat), the boy draws out the broken hilt he found in the barn.
The mere sight of the hilt throws the orc for a loop. “Where did you get that?” he asks Theo. The hilt reforms itself into a dark sword, which prompts the orc to double down on his Theo attack.
