Okay, so it appears left eye is retaining his role from the comics.... which once again we see the very poor quality of writing as this is now a redundant story.
Now, i have altered my theory a bit for this season and i think the mid season end will be a big one.
As we know Gregy boy does not like killing characters, for him and the remaining team its about market research and circumstance over quality of story. That said... lets get into spoilers here....
Spoiler...
That said one of the rumors for 7-1 was that it was not going to be Gizmo and Abraham who bit the dust. But rather Daryl and Abraham. While these were just rumors, we've come to find that at this point, the only time major characters die is when the actor has too many jobs on their plate. And of course the rumors are, that Norman has like four new movies he is going to be doing plus his other tv show.
So my revised theory is going to be, D-Dog-Dixon dies saving left eye at the mid-season end.
And then in one swoop they will have come in and killed all these people in half a season and we will hear all the fanboys say "see nay-sayers, they didnt turn into poor writers who all the sudden lost an understanding of what the show was about" and that will be when you tell them to shut the fuck up and stick a donald trump doll up their asshole.
