YOU HAVE BEEN WARNED!
*SPOILER*
Daryl Dixon does get bitten during the altercation between The Governor and Rick.
The War attracts more nearby walkers and it's the living vs the Dead.
During an escape mission out of the prison the Atlanta group gets ambushed by dozen walkers.
Daryl dies protecting the last of the group. Carol is holding the baby and as she is about to be mauled alive. Daryl is out of arrows. Daryl pulls out his knife and jumps in front to save her and the baby.
A Walker sinks his teeth in his right arm. Daryl fights back and kills the remaining walkers. Carol (almost in tears) says "Daryl, you been bitten". Daryl Replies: "I know, get out, get moving". Carol begins to cry.
Daryl yells at her: "I SAID GET OUT!". Carol takes leave and she sobs out of the prison while the group awaits for her outside.
Rick manages to allude the remaining walkers and invaders. Sees Daryl in shadows and asks him "Daryl! Is everyone Okay?" There is no reply.
Rick becomes worried and asks: "Daryl?"
Daryl replies with a groan.
Rick relizes Daryl becomes a Walker. Pulls his six shooter and kills Walker Daryl.
