Lost: Follow the Sun

Well I was half right. Michael is the spy on the tanker, as I suspected, but now we find out that Sun is the final member of the Oceanic Six. How cruel was that flash-back/flash-forward timeline that led us to believe Jin was with Sun in the future before slapping us in the face with his death? I guess we can also surmise that however the six get rescued, it will happen in a matter of a few months, since Sun is already several weeks along in her pregnancy.
