Ooh, call me intrigued! I like this idea. Interesting that others have pointed out that maybe Clark went to Smallville as an adult, a week ago, and that's why Martha is distracted. I'm going to go out on a limb, though, and guess that even a linguistic phenom couldn't learn English quite that fast (he wouldn't have enough exposure to vocabulary), so maybe he's been around for a while. Or maybe he was sent from... somewhere... and prepped with some language training first. I wonder what happened in Smallville, though! Nice switch of that dialogue line to Lois. I can't wait to see where you go with this!
