Loved it!
It was sweet and fun. I liked the cameo by Mike.
I also enjoyed the idea that someone with so much responsibility wanted to be able to simply serve others. You drew a great parallel between her service and Superman. I very much like that they are able to keep each other's secret. Oh! And the two guys out looking for the missing Superman for "Mr. Big" was a really great touch. It stands to reason that Lex would try to exploit the situation.
Very, very well done.
