A "Catch-22" refers to a no-win situation or a double bind. The literary sense is a situation in which two situations depend on each other to occur. In this episode it refers to the predestination paradox - Desmond only goes on the mission because he sees flashes of him doing so. But the flashes wouldn't have occurred unless he had gone on the mission. So where did the flashes come from?
"Moriah Vineyards" is an anagram of both 'harmed visionary' and 'diversionary ham' and also 'Dharma vise irony'.
The copy of Catch-22 found in the jungle was titled in Portuguese (Ardil-22), the same language the men were speaking in the
listening station at the end of the season 2 finale, "
Live Together, Die Alone"
