Compilation of my observations of potential clues/references and easter eggs from this episode:
=====================
Number reference (23)
Some time-scale clues:
Mentions of "luck" - contrasts/parallels with last weeks reference to Hugo's "Luck"
Fake (or duplicated) Black Box. Also, notice the OS Maps (of the island?) on the board behind Desmond:
Regina's book - upside down (alludes to what the close proximity of the island is gradually doing to all of the boats passengers/crew:
Jin's 2nd bear: Possible side-hint at the Casimir effect and the notion of creating duplicates?:
Jin's Eulogy - dated 22 Sept 2004, the day of the crash, indicating that they (the Oceanic 6) are covering up the true nature/date of Jin's death (if indeed, he really is dead - as Hurley looked shifty in some scenes)
Nikki in Expose on Korean TV in 2005:
Jin's license, except it's not actually Jin. Production error.
The distinctive bed-board in the background shows that Sun and Ji Yeon are living the same apartment that Sun and Jin lived in before the island:
The Kahana - name of Widmore's boat:
Sun has always believed in Karma, that she was being punished for the mistakes she made in her life, and for the first time we have the creators potentially acknowledging that karma has an intentional role in the show, the island and the idea of fate and perhaps more importantly - freewill and the choices we make:
Kate's Map:
Keamy tells Frank not to be late - it seems he is on his way to the island to collect the 'Oceanic 6':
Lima beans: Not sure if there's any layered intention behind this, or whether it's just a shout out to the food situation, but i thought i'd include it anyway.
Mike is back under alias of 'Kevin Johnson'
Note, probably from Michael - which could allude to Ben actually being the good guy, if Mike is his man on the boat:
Proof that the captain wasn't lying about the phone:
Sun's Widmore pregnancy stick (found on island in food-drop) - again showing the relationship between Widmore and Dharma:
An early clue that this was a flashback rather than a flash forward - Jin has gradually lost this type of anger since being on the island
Regina disturbed/RIP:
The stain ala Radzinski:
Two months pregnant (for time-scale purposes):
Year of the Dragon (represents "luck") - 2000/01, tells us that Jin's flashback was the year 2000 - 4 years before coming to the island:
Regina was played by Zoe bell, professional stunt woman and of "Deathproof" fame:
