I don't think they'll get it in this universe, too much damage has been done. :( But DC work with 52 different universes, I work with an infinite amount, and for Smallville/Superman we have three significant ones. lol One where Lex has hair because he was never there when the meteor shower came down. He and Clark never know each other. Then the "canon" one, which I'm afraid ends with that showdown for me... and they kill each other because neither of them can see any other way out. And the third, where everything's alright, President Lex and Kal-El rule the world!
