Pretty cool episode, I won't bother reiterating stuff earlier people said.

However, I'm having more and more problems with the theory around how the zombies and the contagion operate. It's probably me just being too critical and not being able to separate real life from TV life. But:

If everyone is already infected, than we know the contagion by itself doesn't kill you. But the whole premise is that many people since the beginning have died and risen as a zombie simply by getting bit. From a bite or wound that wouldn't be fatal. Just because a zombie wounded them. So which is it? Is the contagion fatal, or is it not?

Unless there is two types of contagion. The dormant kind that lies in wait for you to die, and a modified kind that somehow mutates once you become a zombie and can be passed on to cause death as well as zombification that way.

Maybe they already thought of something like that, but I hope it makes sense.

Also, how the heck do zombies live so long without sustenance? We've seen great numbers since the beginning that are trapped somewhere, no humans or animals to feast on, yet they shamble on. Now it's been an additional 8-9 months. We don't see them eating each other, so what the heck? Any living being needs to replenish their energy somehow. Even if you consider them to be dead humans, they are still a life sort of some kind. They walk around, they expend energy.

Not to mention that most of them have gaping wounds. They'd bleed out. I don't care if your a zombie or not, you need to have blood to survive. Or at the very least to operate your body. You wouldn't be able to move. And even if it is only the brain stem, that still needs blood to walk the automaton around.

As I said, I'm just finding it harder to take that leap, but I'm not sure it could ever be answered, even with fictional TV science.
