S1E3 The Catevari

Title: The Catevari Plot: A comatose patient awakens in a covert hospital, escaping while eliminating the guards with a lethal touch. The Agency is summoned to investigate, and Darien discovers that this mysterious figure, known as the "Catevari"—after a tale of a woman whose very skin became toxic—was yet another of their experiments, just like him. The Catevari targets The Official, but Darien intervenes, using Quicksilver's freezing abilities to save him. In a final showdown, the Catevari urges Darien to unite against their common enemy, but Darien ultimately chooses loyalty to his allies, leading to the Catevari's demise.
