Lex has spent his entire life believing in the utter superiority of his species. Now he finds himself in a human body experiencing emotions completely foreign to him. Bit by bit, pieces of his pragmatic alien heart fall away into something new, something warm, something human. Will Clark be the one to teach him what it means to love? Or will he be the one to destroy him? Perhaps both. Only time would tell and he couldn't wait to find out what Clark would do to him once given the opportunity.
