good interview, he seems to hint another writer is going to be using lois and highlighting her as important as well, I'm guessing he's referring to tom king writing her in heroes in crisis.
Also, yeah, we can chalk up out of character Lois in AC 1004 up to Bendis just writing romance awkwardly, he definitely makes it sound like there is nothing to worry about there.
Based on how Bendis talked about if it isn't a time travel story, I'm gonna go with it not being that. I think Jon will stay as a teen. We'll probably get some event in a few months where he will have to become a boy again though.
