So the guys in the temple are apparently responsible for the whispers followed by crazy creepy walking/teleporting. Glad to see that didn't die out after the 2nd season. This must mean that there are two groups of "others," those that live in the temple and those that follow Richard. They must have some sort of connection to each other, as the ones following Richard went around with lists capturing people, while the captees then find themselves in the temple, and of course they all serve Jacob.

I'm also glad to see the return of "the sickness." This was something that kind of trailed off after Rousseaux's ominous warnings. Apparently those who become sick seem to retain their own consciousness... just become evil. Hence why Rousseaux's husband was able to talk her into lowering her weapon before trying to fire his disabled one. I'm sure there are other characters that, for the longest time, we thought were good guys but were in actuality sick.

What was up with the guy that was pissed off at Kate, btw? She hit him 3 years ago? Must have been while she was captured along with Sawyer and Jack.
