The sophomore episode of season 4 escalates the stakes for the Kent family following Clark's fatal battle.
Skull hesitates. His skull-fires flicker. Then Luthor’s voice, through a neural implant in Skull’s jaw, screams “TERMINATE.” Skull convulses—then detonates himself to stop Luthor’s control. Lois and the boys barely escape into a storm cellar as the Gazette becomes a crater. superman & lois s04e02 dvdrip
