I am actually curious how they will go with the "bleeding eyes" virus. We know already that everyone is infected with the zombie virus since Shane in Season 2, so are they going to play it that this is an external version of the virus that is now infecting people separately from the original virus, or will they make it really dramatic and imply that this is the next "stage" of the virus, meaning at any point, one of them can now just die and turn without any outside factors causing it. I find that to be more suspenseful.
Be aware this is coming from someone that never read the comics, so I have no idea if the story behind this new event is explained.
As for that woman in the woods, I was totally not expecting them to go the direction they did with her. I knew she was going to be trouble, but her "zombie-like" look made me think that she and her husband were actually idolizing the zombies, and would turn out to be cannibals that were going to be taken to the compound and start secretly eating people (since the trailers implied someone killing people in "cold blood", which means pre-meditation, which is not really something you would say about a zombie, since there is really no cognitive excuse for what they do). Instead it just turned into yet another person attempting to keep alive a zombiefied loved one. Was a little disappointing.
