Things have been super tense in future Superman's world this season, and it all comes to a head in this week's new episode, as one-time friends, now enemies, Clark and Lex have a massive fight. This might even be classified as THE fight, the one that seals the guys' fates and means they'll be bitter enemies for the rest of their lives. Sigh. It's also the episode during which one major character – one who's been with the show since the beginning – dies. Any guesses? Don't worry, it's not Clark (he IS Superman, after all), but the big death is someone you know and, well, maybe don't like so much . . .
