Did anybody catch the line Ben said to Jack (I think) about the other random passengers in the tail section? I'm paraphrasing:
Jack: "What's going to happen to all those people back there?" Ben: "Who cares?"
At first I thought it was just Ben being a cold bastard but after a second I started laughing, seeing the tongue-in-cheek reference to how we barely learned a single thing about the Oceanic 815 Tailies.
