I can certainly see the argument for that, because God knows Jor-El has the parenting style of a sociopath. But on the other hand, if Jor-El isn't going to somehow come to the rescue in next season's opener, I don't know who will, which is part of the reason I think it might be more than just Zod all along.

Also, if it was Zod all along, I'm not sure why he didn't just download himself into Clark during that whole summer in which Clark was under his control. Unless of course there was something he needed that only arrived when the ship did, which is a possibility.
