Okay, but has Jon ever switched before or did it just show up? I don't like it because Jon didn't do it before, but more than that, I'm very sensitive to making Jon just like Clark, given I feel he's very much being used as a Clark-standin right now (I didn't like Kon as a Clark standin as Superboy in Smallville, either), and losing his distinctiveness. Anything new (not existing pre-Bendis) that is "just like Clark" is going to irritate me right now because of that. I really hope they never give him a Luthor.
I know Ma and Pa Kent is a thing, just wanted to know when it started. I really don't even like it for Clark, to be honest. It feels more like putting him in a "country bumpkin" or "naive farm boy" box. If it was inherited from older works, I'd get it, but in the older ones I read with his parents, Mom and Dad was more common. But that could just be coincidence, since I haven't read many.
