Everyone gets caught up, Jin learns that Sun was on the plane

Sawyer and Jin find out that Locke is dead and the Jack, Kate and Hurley find out that it's currently 1977. Now everyone is sort of caught up (or so they think). Jack informs Sawyer and Jin that Sayid, Frank and Sun were on the plane too. That is when Jin jumps in the Dharma jeep and speeds off to the Flame Station so see Radzinsky.
