3. Carol The Zombie
SPOILER ALERT: In The Walking Dead comic Carol dies. After her relationship with Tyrese goes horribly wrong Carol goes down hill pretty damn quickly and ends up letting a zombie bite her in a twisted form of suicide. Now we don't think Carol would sink to these depths in the TV series despite being abandoned as she has too much of a desire to live these days but can anybody really survive in the wilderness of the post zombie apocalyptic world? Remember in The Walking Dead it is the living who are as dangerous as the dead and eventually the numbers game will be the downfall of Ms Peletier. How would it affect the group if at some point in the future Carol shows up at the fence outside the prison as a zombie? That could really change the dynamic of the group forever and turn everyone against Rick once and for all.
