Lost season 5

All-right. Caught up to the current and final season - now trying very hard to avoid any hints or spoilers as the show plays out week by week on tv till I can get my hands on the whole lot. Quite a lot of loose ends get tied up in season 5, and the structure of the episodes (and of the season as a whole) increasingly reflects the narratival and thematic preoccupations of the show (most notably, at this point, the time travel thing).
