Well, I have my doubts that Geoff Johns actually wrote his Smallville
episodes to begin with. Other than a story outline and first draft, I find it unlikely given his schedule that he'd sit through doing multiple drafts. Plus, even if he did write every word that ended up on screen, I'm pretty sure he'd be privy to the plans for the rest of the season so his episode could integrate in what was to come. Also, despite the stupidity of Kryptonite Girl, making someone into a superhero is
a great destiny in the world of comic books.
However, I did smile when Lana became literal poison to Clark. I wonder if that was a subtle jab the writers took at themselves given fan complaints and the previous seven years.
