Jon needs to be younger. Like...7-3 years younger.
But aside from that, he needs something that's all his and not Clark's...besides being Clark's son. He's got the costume that's damn near identical. He's stationed in the same city. Not really doing anything that Clark wouldn't/couldn't do or hasn't done before. And now he's got his reporter love interest. At the very least give him a major that has nothing to do with writing/journalism. That is, if there's ever any focus on his college life at all (and given how he seems to be glued to his Superman costume 24/7 I'm kinda doubting we'll actually see much of him in school)
