SPOILER WARNING: This article contains major spoilers for "The Faithful," the latest episode of Supergirl.
The mystery of Reign's origins just deepened. In "The Faithful," the latest episode of Supergirl, Samantha Arias -- who is destined to become Reign -- had a startling vision. What's worse, that vision seemed to be triggered by new movement on the Kryptonian ship in National City's harbor, which was revealed in the Season 3 premiere.
As the episode drew to a close, Samantha began to unwind after a long day at her daughter Ruby's recital. She reached into her medicine cabinet to put something away, but -- after she closed it and saw herself in the mirror -- her reflection had changed: every inch of visible skin was covered in Kryptonian writing.
She gasped when she saw her reflection, only to turn and see a hooded figure. The hooded figure's face was so decayed and grotesque that she screamed when she saw it. Samantha curled into a ball on the floor and cowered as the figure approached, its face flickering between its decayed state and the visage of a young woman.
Ruby turned the corner to find her mother in that state. When she saw her daughter, Samantha snapped back to herself. She checked her hands and found them back to normal; what's more, the figure had completely disappeared.
The episode then cut back to a scene from earlier in the episode, where Kara burrowed deep into the ground with her laser vision and pushed a bomb into the hole. The hole was so deep that the explosion rocked the ground miles away -- even as far as National City harbor, where a spaceship lies dormant beneath the water.
This time, however, the episode revealed what was inside the ship. In the ship pulsed a deep red light, which revealed several pods. All but one pod was filled with shapeless black masses. The camera then panned over to one singular pod. Just before the credits rolled, a skeletal hand pressed up against the glass.
It is unclear just what those pods contain, but -- if the ship truly came from Krypton -- it could contain other creatures like Reign. After all, there are a total of five Worldkillers in the comics, which means Reign could be part of a set. Notably, the term "Worldkiller" hails from Kryptonian mythology, the primary theme of "The Faithful."
