What significance would Catch 22 have for Desmond? The book he carried with him was "Our Mutual Friend" by Dickens. That's the book Penny would associate with Desmond. Sure, Catch 22 was in the hatch, but how would Penny know that? As to the earlier post about Penny's dad sending Naomi because he has an interest in Desmonds ability to see the future....how would he know that unless he's watching the show?
