I became so frustrated by last season of “The Walking Dead” that I stopped watching. I eventually went back and finished Season 2 — which did get better at the end, and is currently streaming on Netflix Instant — but if you want to just jump in with Season 3, here’s a quick rundown of the big plot developments.
Beware major spoilers ahead
Dale (Jeffrey DeMunn) is dead. He was mortally wounded by a walker, and Daryl put him out of his misery. Sad to see an excellent actor like DeMunn leave the show, but his character had become problematic.
Andrea (Lori Holden) was separated from the group when Herschel’s farm was overrun by walkers. She is eventually saved by the samurai sword-wielding Michonne, who also has two armless walkers on chains in tow.
Everyone is infected with the virus and will regenerate into a walker when they die, regardless of whether or not they’ve been bit. This is what Dr. Jenner (Noah Emmerich) whispered to Rick at CDC in the Season 1 finale.
The very big spoiler
Shane (Jon Bernthal) is dead. After becoming increasingly unstable and jealous of Rick, Shane leads Rick out in to the woods to kill him. Rick gets the upper hand and stabs Shane. When Shane becomes a walker, he’s killed by Rick’s son Carl (Chandler Riggs). Later Rick tells the group about killing Shane, that everyone is infected and he is now the unquestioned leader of the group. If they don’t like it, they can go on their own.
