I still refuse to acknowledge that character as Jon. That is Earth 3 Ultraboy, inserting himself deep within Earth 1/Prime/whatever and relaying information to the Crime Syndicate. Real Jon is stuck in the Daycare from Hell on Earth 3, with his powers neutralized, and dealing with annoyingly evil things. Like pencils that stay dull, frustratingly inaccurate educational materials, awful tasting healthy food, etc.
