This is all about
Sayid and the question "If you could go back in time and kill
Hitler, would you?" In the case of
Lost, that would be
Ben. So, it's all leading up to when
Ben helps
Sayid escape captivity and the moment of truth, does
Sayid kill
Ben? The answer is
Yes. Everything leading up to the ending was great, especially seeing how
Sayid was caught and handcuffed getting onto the plane that brought him back to the
Island.
