Because the only way I could process my frustration with this episode was to rewrite it. Enjoy!
A what if story set during the episode 'Man of Steel' - what if the RV had recognised Clark as an intruder when he snuck in during Lois' chat with Marcus Bridgewater (AKA John Henry Irons). The resulting changes in events set about a very different direction for the characters and brings up memories of Lex Luthor's history with Clark and Lois.
