Zod continues to pose as "The Blur" and asks Lois to investigate one of Tess's secret labs. An explosion rocks the lab, and Lois is rescued by John Corben (Brian Austin Green) who was a subject of multiple experiments. While investigating the explosion, Clark is exposed to red kryptonite. And the infected Clark takes Zod to the Fortress. Tess turns to Chloe for help -- and they send in Corben to stop Clark from revealing all his secrets.
