I certainly hope that Clark is smart enough to figure out that Jo and Lois are one and the same before too long.
I find it funny that Lois is pretending that her flirting with Clark is all just a part of her Jo persona. I know Lois doesn't like to admit her feelings but that is definitely a knew tactic for ignoring them. To pretend that these feelings only belong to your imagined undercover persona.
Really enjoying this story so far and looking forward to the next part.
