I am rewatching the episode and I caught something in Jacks story. He said "She tried to save the other 2 but..."

Basiclly that means the other 2 died and the reason it was in his story was for realism purpose.

The way he was telling it clearly meant they died quite early in the story. AKA died soon after the crash. Because he said "She tried to save them" that was during her hero period which was immediantly after the crash.

Therefore the other 2 oceanic are worthless. But the interesting part would be who he choice as the other 2.

Of course I could be wrong. But I'm probably not.
