Tess discovers that General Zod's associate, General Slade, was found unconscious on a street corner, indicating that someone has accessed the Phantom Zone's escape portal and sent him back to the physical world. Concerned, Clark decides to return to the Phantom Zone to ensure no other exiles are escaping. He becomes angry when Oliver tricks him into taking him along. Without his powers, Clark and Oliver are quickly captured by the Zoners and brought before their new leader, Zod, who is determined to seek revenge against Clark for banishing him to the Kryptonian prison. Meanwhile, Lois learns that Clark confided in Tess about a secret but did not share it with her.
