It is looking more and more likely that the next episode of Lost will be Jin & Sun-centric and it is being reported that there will be a major shocker in their relationship.
In the episode preview, it was clear that The Man In Black/Fake-Locke was offering Sun a chance to see Jin again by joining him and keeping her allegiance away from Jacob/Richard and company (as well as knocking another candidate off the list). But the shocker is apparently that they apparently ARE NOT married.
Other fact’s about the next episode include Fake-Locke explaining what is needed to leave the island (presumably to kill Jacob’s replacement), a female character being marked to die next and some sort of package.
