Hmm... they're newlyweds, right? Alexa's husband desired her behavior to be different? Less... diminutive in certain areas of their married life? Or maybe, this just coincides with an original plan of Lex to have Lois's behavior 'adjusted' to his needs? [Peep] Just saying... There's lots of reasons that have absolutely nothing to do with turning Alexa into a gun for hire.
Well, I'm REAL sure Lois would not do that to Clark.
Yet.
