The Walking Dead - Episode 2.12 - Better Angels - Major Spoilers

Here's a description of how Shane dies.

"Lori starts a dramatic war in Episode 2.09 where she tries to convince Rick to kill Shane. Rick thinks about it but shrugs it off. After Lori sees that Rick is still not acting, she has a talk with Shane and puts into his head that if Rick wasn't around they would still be together. This makes Shane change AGAIN, (he had finally made peace and Lori fucks him up again). Lori warns Rick that Shane will probably attempt to kill him, Rick denies it and says they've made peace. Anyway Shane decides to kill Rick and lures him into the forest chasing after Randall. Of course Rick isn't stupid he realizes nothing is adding up and tries to give Shane a chance to abandon his plans. Believe it or not Rick loves Shane like a brother, anyway he finally calls Shane on it and says he knows what he's trying to do.

So it starts with Rick standing off with Shane, they're kinda on plain land I guess outside the barn (I mean far from it, like just outside a forest, and it's moonlight). Rick says something like "so this is where you planned to do it".

Shane says something I can't quite make out, I think he was acting oblivious and playing stupid because Rick says something like "at least have the balls to call this what it is....murder" so I can assume that Shane was playing dumb.

Rick circles Shane talking about how you think if you go back to the farm alone they'll believe whatever fucking story you cooked up (not exact quote, cept the fucking part) and Shane tells him to hush up and the group will believe him.

Rick doesn't buy a word that Shane says.

Shane finally admits "it ain't goin to be easy, but Lori and Carl will get over you" and you can tell by the look on Rick's face that he's starting to lose his patience. Shane adds "they done it before, they just gone have to" and pulls out his gun to aim at Rick's face. Rick asks why? Why now? He then says "I thought we tried to work this out". Shane laughs and says "we tried to kill each other!" (referring to the fight in 18 Miles Out) with his gun still on Rick.

Shane continues to mock by saying "ya think we're just gonna forget about it and run into the sunset together?" Rick asks him "are you gonna kill me in cold blood? Screw my wife? Have my children... my children! Call you daddy? Is that what you want?"

He says something else that I couldn't make out, and Shane replies something like asking him what does he know what to live for or something? I'm sorry I couldn't hear it though I could be wrong.

Shane talks about how Rick has no idea what he had to, and still has to live with. Shane dares Rick to raise his gun, but Rick refuses. Shane taunts him by saying "what happened Rick, I thought you said you weren't the good guy anymore?" He continues to mock, saying that he's a better father than Rick and that he's better for Lori than Rick because he's a better man than Rick and he'll actually fight for Lori (the stuff that Rick basically told him in '18 Miles Out' Shane is twisting his words against him, and this pisses off Rick.)

Shane says that Rick came back and destroyed everything. Pause. He continues by saying Rick has a broken wife and a weak boy. He also adds that Rick doesn't even know how to fix it, he then pushes his gun closer to Rick and tells him to raise his gun.

Rick asks something like you gonna shoot an unarmed man? Pause. Rick slowly goes for his gun and then pulls it out as if to drop it. Shane keeps his gun trained Rick. Rick tries to negotiate saying "there's a way back from this, nothing happened here, we gonna lay down our guns and walk back to the farm."

Shane looks conflicted, not knowing that Rick has drawn his knife (the one you see him use in '18 Miles Out'), finally when Shane doesn't expect it, Rick lunges his knife into Shane's chest.

Even worse HERE'S A BIG SPOILER.

SHANE COMES BACK TO LIFE AS A ZOMBIE! - Carl shoots him, the whole thing is pretty fucked up but I won't give too much away .

All this causes Rick to slowly change into a 'Shane' if you will. Believe me the show is going somewhere so crazy that Shane's death will not even be a burden, he served his purpose by helping Rick's character transform.''
