I dislike a Phantom Zone where the "phantoms" have solid bodies, fight with swords, can be killed and cannot see outside the Zone. Do they need to eat?
Since Booster Gold is a time traveller, it does make sense that, if he wants to displace Superman in history, then he should arrive before Clark has become Superman.
Are there still Smallville: Season 11 comics? If not, then this is a closed continuity although there are now two other screen continuities, a movieverse and a TV multiverse, each with a Superman.
