Welcome to Lostpedia Answers. What would you like to know?

They hadn't been introduced to each other or talked to each other before, however they had seen each other. This was in season 4 episode 1, "The Beginning of the End". When Hurley, Sayid, Sawyer, Desmond etc left the beach camp to go to the radio tower and meet up with Jack, Kate, Claire, Ben etc, they all met up at the plane wreckage. So Ben and Desmond would have seen each other but they didnt talk until the events in Episode 6 of season 5, "316".
