You can definitely see the envy in Carl. Especially when Negan brings him in and shows him all the Saviors bowing down to him. After Negan leaves he sort of stays for a second and goes to the rail and tests it out. He considers it. He’s never seen anyone with this much power before. No one has that much respect for Rick, so for him, that’s crazy, and kind of a cool thing for him to see. For Negan to kind of hint at offering that to Carl, it’s really surreal for him.
Also, Negan’s the only one who treats him like an adult. He’s the only one who sees Carl as an equal. No one else has that kind of respect for Carl. The more Negan treats him as an adult, the more Rick treats him like a kid, and that’s a problem.
