Fic: All the Difference, part 3

After watching JLU concurrently with Smallville, it's difficult to keep their canons from getting entwined in my mind, especially since the SV Clex backstory fits in so nicely into the tetchy Supes/Luthor relationship JLU presents. However, I never intended for this story to be a crossover. Therefore I'm at a loss to explain how the Batman keeps sneaking in. I suppose sneaking into things is one of his specialties. And he is a convenient foil.

Please forgive typos and grammatical flubs (do point them out, just don't laugh at my idiocy when you do - not that anyone has, you've been very nice about that!) - gnine was a dear sister and beta'd this for me yesterday but I'm posting on very little sleep now, being as Lex was prodding me to write him smashed (Lex smashed, not me) at 6 AM (My 6 AM, not his; it was about 1 AM his time, and Why can't you just pass out when you've had that much scotch? I ask him; but this is Lex.)
