Surely they wouldn't play up the 'significant development' teaser over a positive ID that it's already widely accepted as that of Robert, right? I wouldn't think that would be cause for a press conference and the hush hush as to it's content NOW, would you?
We already know they've ID'ed the poor child. I'm anxiously sitting on the edge of my seat praying that Robert has told them 'how and who!' Please God let this child's voice be heard.
