Lol yeah, I get that. That he's a Luthor would probably just confuse Jon. But yeah, Jon's anger would more so be based on the fact that anyone would even think to call themselves Superman so soon after his disappearance. He doesn't even think that it should be him to take up the mantle. It scares him to.

Partially same for Kieran. He's not "scared" to take up the mantle but he's not sure if he's ready or even worthy of it despite him being a full Kryptonian and one of the "sons" of Superman despite not being his biological one. But he'd probably feel some kind of way about Julian calling himself a Superman.
