John Henry Irons warned
Superman that a war was coming, and while his opinion of the Man of Steel may be wrong, his talk about the war was not.
Superman & Lois officially confirmed that
Morgan Edge is building a superhuman army, and using the X-Kryptonite-exposed citizens of Smallville to create that army. Why would he do such a thing? As we learned in the latest episode, it's because Morgan Edge is actually a Kryptonian.
Superman found this out when he confronted Morgan Edge at a remote location and was blown aside by the casual backhand by the Season 1 villain. Edge then informed Superman that he too is a Kryptonian and that he was sent to Earth around the same time that Superman was. He also referred to the hero as "brother," which is another head-spinning reveal. What does it all mean?
