Abraham is the man I found most relation when I read the comics, and I only have to raise a hat to a wonderful adaptation of this scene. He is a man with a mission, and while he has one, he cannot fail. That's what kept him alive over the seas and that's what kept him alive so far. But not any more. he has even less of a purpose now than at back then when eat the pipe and thought about the final solution.
Rick went through that same phase and that broke him. You saw it. He started talking to the dead people. What will happen, I don't know. I'm as blind as you're as I know that things has gone awfully awry this year. And they are not following the script. So it makes this situation really interesting.
a) They have a man without a mission, without a reason to live as far as Abraham sees it in this world. So he breaks down and hits the swarm with a one thing in his mind. The end.
b) It's the long way around, knowing that they have sent Rick on the path to Washington. Abraham collects his bones and sulk at Eugene, while the group really understands his value and the purpose of finding out what the Capital knew about the infection. After all, isn't that the neighbourhood where they could find some answers, and possible quite wicked "executive" hideouts.
c) It's short road back, but it's mighty thing to swallow for the man who has lost his world. He purpose. Abraham bashes Eugene once more to make sure that the moron knows his place, and the wrong he did. He grins all the way back to the Church, where Gabriel gives them a small talk about the way of forgiving the sins. The big man breaks down and ask for Eugene forgiveness.
d) They all ready f**ked up by shouting and the hoard is on the way. Someone dies for sure. They catch up with Rick's group on the way to Atlanta to save Carol and Beth from the bastards that locked her in the seclusive slave camp, and their leader whose waiting for the Government propelling with special anti-zombie units and pockets full of anti-zombie medication.
e) We don't know, because Mr Kirkman is one evil person and the moment you think you know, he proves that we know nothing.
Whatever it is, the one thing I know is that the sadness hasn't stopped. There is no glimmer of hope. Everyone has it and it's either do or die, or go through necromorphosis and become soulless monster that ravages any living in sight. That hoard was there for a reason and in my mind I see them as the ultimate clean-up crew. They simply will either get their prey or they force their victims in devilish situation, where at the end your either break it through it or you become part of the army of the walking dead.
They are at the moment getting to a point, where the hoards big impossible wide and therefore, as difficult to stop as they will trample through the area to find anything to put in their stomach. There's no doubt about that in my mind. You just watch that trampled grass they had spilled all over the road because to me it looked as if tens of thousands had just walked into that town.
May Lord be gracious and offer guidance to those poor souls still trapped in there.
