Secrets are revealed and Brainiac's true plan is uncovered in a sneak peek for next week's episode of Syfy's Superman prequel series, Krypton.

In the series premiere, a time-traveling Adam Strange (Shaun Sipos) came to Krypton to warn Superman's grandfather, Seg-El (Cameron Cuffe), of a conspiracy to prevent the birth of his future grandson. According to Adam, the plan was being orchestrated by one of Superman's oldest foes, Brainiac (Blake Ritson). As the "collector of worlds", Brainiac plans to destroy Krypton. After much convincing, Seg eventually came to believe Adam and has been working with him to stop Brainiac from achieving his goal.

A sneak peek for next Wednesday's episode, "Civil Wars", sheds new light on Brainiac's intentions. In the clip, General Zod (Colin Salmon) explains that Brainiac assimilated the city of Kandor into his collection, which destabilizes Krypton's core. This results in Krypton's destruction 200 years later. What this means is that this version of Brainiac isn't from the future. If Zod is correct, Brainiac's plans for Krypton never had anything to do with Superman; his actions are actually a part of Kryptonian history.

The reveal comes as a big shock to Seg, who puts two and two together and figures out that Adam knew all along that Krypton was destined to be destroyed. The clip ends with Lyta Zod (Georgina Campbell) disarming Adam and pointing his gun at him.

The clip shows that the twist at the end of this week's episode, "House of Zod" was a major game-changer for the series. General Zod, whose identity was confirmed by Krypton's showrunner, could change the way the main characters will try to deal with Brainiac. A trailer for the episode reveals that Zod intends to unleash Doomsday in an effort to defeat him, a decision that has the potential to have devastating consequences.

Finding out the truth about Brainiac could totally change both Seg's and Adam's plans as well. If Zod is telling the truth, then continuing to stop Brainiac would defeat the purpose of Adam's mission. If Brainiac fails and Krypton is saved, Superman would never be sent to Earth. Seg, on the other hand, will be faced with an incredible dilemma. He can accept Krypton's fate and let his planet be destroyed so that Superman's destiny can remain unchanged, or he stop Brainiac, and change the future forever.
