[neverending]

Well, you can't really explore the concept of immortality without some characters that are immortal. Does it have less "impact" when the apparent death of a character turns out to not be final? Sure, in one traditional sense, but the death means something different in the long run. :scared to death:

This show has never done things the traditional way. They've always twisted things around and they're doing it again this season.

And they have addressed the issue of Zoe being the supreme. I can't recall the exact scene, but it was in an early episode, and ever since then the others have been trying to prove they're the next supreme. Zoe is a shrinking violet, so she doesn't push the issue. You guys may be right that she will be revealed as the one in the end. If so, I'll see how they handle it. The finales have tended to be a mess. We'll see what happens this time!
