Great episode!!!!!!!!Any theories on who died and why Jack regrets leaving the island?My theory: I think when Ben warned Jack that he would also be killing his own people as he had done himself (with poison gas), he was warning him what would happen if they are rescued. By answering that phone, he wasn't rescuing them... but rather condemning them to death. This explains why Jack became so distraught after reading the obituary of a person he was neither a "family or friend" to.... why he was such a messed up drunk/drug addict..... and why there was no one at the funeral/wake.... because others were also dead. Too bad we won't find out for at least 8 more months!!!!!!! Damn that's a long ass time!
