Major spoiler warning: Stop reading now if you don't wish to know the true identity of a certain character on Smallville.
Okay? Ready? Here goes...Alexander is Conner Kent.
Indeed, as teased in the final few moments of "Beacon" - when Tess tried to inject him with cyanide - the Luthor clone (portrayed by Lucas Gabreel) will soon be revealed as Superboy, the human hybrid of Kal-El and Lex. TV Line broke this scoop.
Said Brian Peterson and Kelly Souders in a statement: “Conner’s journey is manipulated by a master. Luckily, someone knows more about Conner’s life than he does. But he should be wary of strangers bearing gifts.”
