It's most likely to be Conner. L-1/Savage mentioned in the pilot that Conner's escape could be turned to their advantage, and having a brainwashed agent (especially one as powerful as Superboy) in the Team's midst is certainly quite the advantage. Like Batman said, little is known of the extent of Conner's programming. He could be a Manchurian agent, unaware that he's betraying his friends, and will probably remain unaware until it's too late.
