This was a great one-shot! I was confused as I read it--but it was a good kind of confused. Lois's emotional state is absolutely reflected by the writing, and you did a really good job with that. It is great how the dialogue at the end sort of gives some focus as Clark pulls Lois up out of her slump.
Your usage of the license plates and the before-Lois and after-Lois thing was handled very nicely. Very great job with this story!
