2. Will Jin and Sun Reunite?
The couple (Daniel Dae Kim and Yunjin Kim) came to the Island unhappy with themselves and each other. But over time, they patched up their rocky marriage and even conceived a child. Since then, they've been separated by both space (Sun escaped the Island in season 4) and time (Jin started time traveling in season 5). The couple is together again in the rebooted world, albeit in (seemingly) shaky season 1 form. In the other world, both are back on the Island, in the same time period — but TBD on when they'll reunite. FYI: The producers say viewers won't explicitly be told why Sun did not go back in time with the other castaways on Ajira flight 316 — though fans may be able to puzzle it out for themselves.
