Suddenly a lot of stuff comes together. Now we know what was going down with Adam, who could more properly have been called "Lazarus." The theme of Luthor secrets will continue. What will become of Dr Teng?
We did not see how Vince escaped from the secret Luthorcorp lab. Presumably he was not meant to?
Clark lies to Lana right at the end. Superman's entire career is based on deception. I remember that the Kents were always telling "white lies" in Superboy comics.
