what i want to know is if my explanations work and if you think any of what i've said should be worked into the story (added to this part as introspection, perhaps). do i still need to change anything? add anything?
Seems logical to me for the most part.
Her behavior towards Luthor is typical for this period of time, so I guess her reaction to the bugging makes relative sense, re my comment about her being in her right mind. At this point in time, she literally does nothing anytime she's confronted by any sign of Luthor's villainy whether it be bugging her office or Lexel Investment's extra insurance policies. She's so willing to believe him that she'll rationalize away anything, but never gives Clark a break on anything he does.
But eventually, her privacy would be a big deal and she would have it out with Luthor before the wedding, if nothing more than to say that he won't be controlling her life once they're married. I just can't see her sitting still for something of this magnitude for long. And Lex will of course pretend to agree, and will then proceed to bug her apartment (if it hasn't already been done) and adding more bugs that are better concealed in her office. We know her car's already bugged. So I would have preferred some introspection that was stronger to the effect that she was mad at Lex but would deal with it later, rather than just saying that Luthor's willingness to invade her privacy was "not a good sign." That shows an almost indifference, whereas she said Clark wouldn't live long enough to regret it for a similar, and actually lesser, transgression. She's also mad at Clark for something he MAY be doing ("checking up on the little woman") versus almost indifference with Luthor who's been caught in the act of real spying. I would prefer something along the lines of, "if anything remotely like this happens again, he's history." A Lois in her right mind wouldn't even give him a second chance. He would have immediately moved into the distrusted federal disaster category. To me, that was the only weak spot to me in an otherwise enjoyable part.
