During the short period he was writing Superman, he was writing Lois as a controlling jealous shrew, Lana as a homewrecker openly making a play for Clark (this was right after her divorce IIRC), Clark as a henpecked husband tempted by his high school girlfriend and Martha has someone who would have openly supported Lana over Lois for a D-in-Law. Typical Austen hackery, he gave interviews openly talking about his dislike of Lois, preference for Lana, etc. and he ended up writing his final issue under an assumed name after DC kicked him off the book because of fan backlash (again its been years but thats what I seem to recall). Everybody acted OOC when he was writing Supes (just like when he wrote the illogical Nightcrawler becomes Pope plan in X-Men or the Wasp/Hawkeye affair in Avengers).
