So what did they reveal? A few things...
- Libby's story will be told this season.
- Rousseau's flashback will either be late this season or next season, but its timing will be linked to some other plot point.
- Ben did not intend to get captured in Rousseau's net when we first met him, and the destination to which he was headed and what he was going to do there will be revealed.
- The explanation for smokey will come, but it will be like the revelation that Kate really wanted the get the toy plane in that some people might think, "really? that's it?"
- "Cerberus" on the Swan hatch map is a reference to smokey, but it's not the monster's only name.
- "CV" on the Swan hatch map stands for "Cerberus Vent," meaning spots where smokey surfaced from underground.
- The series will not end with Jack and Kate as we saw them in the finale. Flashforwards will come from time to time, and it will not always be abundantly clear how far in the future they will be.
- Flashforwards have been planned since late in season 1, as there can only be so much interesting backstory for these characters.
Anyway, you see the discussion for yourself. But even if you don't want to watch just the talking heads, check out the last video below - apparently raw footage from another DHARMA orientation film...
