Yeah, I'm not really articulating what I'm thinking clearly. I just did my taxes so my brain is not firing on all cylinders!
I do think part of the age up was to make Jon, Lois, and Clark all a little more independent from each other. Until we know how they are going to address the age up and Jon's paternity in the context of the secret identity it's hard to say. Jon may end up living with "Clark" in metropolis or with "Superman" at the Fortress. All dependant on how that shakes out. We know Jon's paternity is going to be revealed publicly at some point. Those janitors overheard that part of it and it'll likely come out in the post-Unity Saga arc.
