I was kind of disappointed that "SUNdown" wasn't about Sun (while "LOCKdown" was about Locke). Really doesn't matter.

Interesting that the lines have been drawn, and who is on each side.

On one side we have:

ZombieLocke/Smokie/Esau/Man in Black/The Man Outside
Sawyer (Candidate 15)
Claire
Sayid (Candidate 16)
Kate?

On The Others side:

Jack (Candidate 23)
Hurley (Candidate 8)
The Kwans (Candidates 42)
Ben
Lapedius

Basically, all of the characters I don't care about are on the Evil side, and all of the characters I like are on the Good side. Yay for me!
