Even though the Kent family principles have held with Jon, how is he a different Superboy, super man, than his father?

He’s immensely proud of himself for getting home. He kind of shows you what kind of Superman he is, and then he’s going to describe that in the flashbacks. Jon and Clark/Kal are going to head back out into the cosmos to deal with Grandpa. And just because he’s been through a lot, he’s still a teenager and he’s still going through things, so he’s not fully baked as a human being yet. He’s still in process. If anything, Clark gets to come in just as he’s getting really interesting and try to do be the father that he needs to be for him. You’re going to find out what kind of man Jon is becoming.

Speaking of Grandpa Jor-El, he must be dealt with, but doesn’t Kal-El already have a lot on his plate with Zod, Rogol Zaar, etc.?

Kal-El has a lot to deal with on his end, right? This is a family crisis. “What did Dad do? Why did he do it, and what do we do now?” These are very big questions that we’ll have a big answer in the next few issues of Superman and lead to, may I say, an enormous story. I’ve been telling people this saga builds and builds, and I think now you can see this extra piece of Jon, and where Jon and Superman are going must go deal with what happened with Jor-El. You can kind of see how big the story could get.
