So remember in Season 4 when Frank asked Juliet her name and then freaked out and told Miles she was "one of them" saying, "I've memorized every name on that list..." etc. What about Desmond??? He hung out with Frank at the helicopter for a while and had a conversation with him before giving him a ride to the boat. Are we to believe that Desmond told Frank his story and he believed it with no suspicions that he was an Other? I'm sure this is just an oversight by the writers but what do you guys think?
