Anyone notice that when they showed Lex's computer screen, we saw that Adam's supposed last name is "Knight" as in "The Dark Knight"?
Although, it bothers me that he said to Lex that his parents would have killed for a nice piano. If he really is Bruce Wayne, wouldn't his parents have had enough money to buy a phat piano seeing as how they were billionaires?
I don't think Adam's Bruce Wayne, maybe something to do with Lionel and the clones from last year?
