Corrected entry: Desmond claims that he was saving Charlie's life by saving Claire from drowning by jumping in before he does. However, if Desmond had not had a flash to witness the event of him dying, Charlie wouldn't have known it was happening either as he followed Desmond to the event. As we find out later, they were a mile inland, so there's no way Charlie could have found out until a long time after Claire had drowned.Life700
Corrected entry: In the London pub, Desmond refers to the barman as the "bartender", a word never used in England. He also gets a drink without paying, leaving money on the bar when he leaves - this may be the American way, but in British pubs you always pay when you receive your drink.
