I'm surprised that Lex slipped the way he did on Clark being in the building. Then again, he probably couldn't resist a desire to be the person that told Lois that Clark was dead.
I knew from the onset that Lex was going to make his first slip there - He knew it was Clark's building that burned and there were no survivors. Why would Lex even know where Clark lived to make the connection? And so the light starts to flicker in Lois's head...
