On the odd chance anyone but me or a Z watches this - did you see that coming? I totally did not see this coming.
From reading reaction elsewhere, I understand CBS was airing some sort of teaser ad that hinted in this direction (I never actually saw it, or I saw it and it made no impact.) What a blindside to end the season.
If there's an improvement to be made, they really should've ended the episode two minutes earlier, with everyone reacting to the ending, rather than try and go with the happy drinking family final scene.
Meaning if Shanon decides she is seeing Walt others mightl see him as well, or Kate with the horse or even Locke and Eko thinking they can use the computer for communication and suddenly it communicates. Do not mistake coinsidence for fate.
