Episode Title:
Mixed Signals.
Episode Description:
During a battle with a starfish-like EVO, Rex suddenly loses control of his powers and begins building strange, unidentified machines. At the Providence HQ, Rex assembles these machines into a large construct, which creates a force field which captures him. The HQ is then infiltrated by a mysterious man who releases Rex and reveals himself as Caesar Salazar, Rex's older brother. Caesar takes Rex away from Providence, and explains his past: Caesar, along with Rex's parents Rafael and Violetta, was one of the scientists who worked on the original Nanite Project. During the Nanite Event, their parents were killed, and Caesar's aircraft was caught at near the speed of light, resulting in time dilation which sent Caesar five years into the future, explaining his absence from Rex's life. Caesar takes Rex to Abysus, where they are attacked by Van Kleiss, who recognizes Caesar. Rex and Caesar escape, and Caesar helps Providence defeat the starfish EVO using his advanced scientific knowledge. Recognizing Caesar as a potentially valuable asset, White Knight hires him as a scientist, though Six remains distrusting of him.
