That Lex is dead is good. That Lois killed him is not. Even if she wasn't trying for dead (which I think she was), killing another human being is an extremely traumatic experience, especially if the victime is well-known to the killer.
Clark is going to have his hands full helping Lois through this situation. She's crossed a line that most people don't ever get close to, and it's going to affect her for the foreseeable future if not for the rest of her life. And how will little Jon take learning that Mommy kicked Daddy over a balcony railing and splattered him all over the sidewalk? When will she tell him? Will he view Clark (who surely will be his stepfather) as an interloper?
What will she tell Jon about Lex? How will she explain that this boy's father was a sociopathic monster? There may only be one more post on this story, but it's not over, not by a long shot.
Oh, by the way, it's excellent. Having Lex undone by his own vanity (keeping a loaded weapon in his private museum - how stupid is that?) is a stroke of ironic genius. And I could just see Lex's face lose its smugness as the "minor details" kept piling up. The razor banter between Lois and Lex was outstanding.
Keep up the wonderful work! I can't wait to see how it ends.
