Remember when it seemed bold for Krypton, the show we expected to be a Superman prequel series, introduced the time-traveling Adam Strange, General Zod, as well as Brainiac and Doomsday? Well, hold onto your red trunks because – after the second season went further with Lobo, Brainiac’s homeworld of Colu, Doomsday in action, and the Black Mercy – the Krypton season 2 finale tees up a Krypton Season 3 that should further expands this corner (and alternate timeline) of the DC Universe.

But the finale also opens up a lot of questions that will have fans speculating until Krypton Season 3 premieres (although its renewal still has to be announced). Let’s break down the big ones from tonight’s season finale.

Will Kem-El return as Kem-L?

To honor Kem, Val tells Seg that his best friend from the Rankless District will be honored with the “El” surname, officially making them brothers. Although Kem lost his head in a battle with Doomsday and didn’t look like he was in any shape to come back from that, the name Kem-El officially places him within Kryptonian lore. Created by Dan Jurgens in 1989, Kem-L/Kem-El was a xenophobic scientist in Krypton’s past who developed Eradicator, which was (at least initially) an alien device altered to preserve Kryptonian culture, and prevent anyone from leaving the planet.

Though the Kem we knew and loved doesn’t seem much like an intolerant scientist (and the original Kem-El existed long before Seg in Kryptonian history), death can do weird things to people. Might the show decide to bring Kem back as a villain? Names have meaning, and stranger things have happened. And actor Rasmus Hardiker could pull off evil.
