Clark discovers that Lois is a shape-shifting alien that's on the run.
Hahaha! If you don't write this I might have to.
CLARK: You're so beautiful, Lois.
LOIS: Rats. I didn't want to be *unattractive* but I didn't want to draw too much attention to myself.
CLARK: Uh, what?
LOIS: Just don't fall for me farmboy. You don't know what you're getting yourself into.
OOH! She could be Martian Manhunter!

Or a feminized version... J'oanna J'onnz
Stop this bunny madness! I can't take on any more!
