Lana is going to school in the series in Metropolis, so like Lois she won't be around as much this season.
I was wondering why Jor-El didn't lend a hand once Clark removed that evil shard from the console.
I don't read a lot of Superman comics, but I know in Frank Millers' the Dark Knight Returns Batman is like 60 ish while Clark is still stuck in his early thirties, so who knows how Kryptonians age?
