I just finished reading Superman: Last Son by Geoff Johns & Richard Donner, which I enjoyed immensely. But if I made a complaint, it would be that we don't actually see much of Clark and Lois raising Chris, so the impact of his "loss" at the end is somewhat dampened. I know he popped up elsewhere during this time, but I can't find a decent list. Does anyone know where he made appearances? (And if they're collected in trades?) I'd like to read more about the kid.
