I really have to hand it to the producers (or the authenticators) of this show. They came out of the gate asking the hard common sense questions, and pretty much backed him in a corner by bringing in CSA. They knew it wasn't real from the get go, but their 'mission statement' is to be as close to 100% certain as possible.
I also felt that Edwards really thought it was authentic, and everyone up to this point were just being mean.
Last week they proved a Lalique hood ornament was authentic. The guy paid $1200 for it in a charity auction. Worth $300K! I am hooked.
