Has this already been thought of ? I apologise if it has and has already been blogged but hey:
6 characters get off the Island - 6 numbers (4, 8, 15, 16, 23 & 42). Maybe some sort of connection? There could be a relevance to the producers picking six characters to get off.
ALSO: will Aaron EVER return to the Island? Will we see him again? No spoilers please(obviously).
