The episode was really awesome!
It began when Glenn told whole group about the barn. Shane, of course, was definitely pissed of. Now this safe harbor isn't save anymore. No it's all about decision to stay here or to leave.
Dale tries to hide guns to avoid crazy Shane have one. But it's not his call and Shane take them back to perform barn zombies massacre. But there are still debates at this point.
Meanwhile Hershel teaches Rick how to catch zombies and force them to the barn. And when they brought zombies to the barn Shane has completely gone crazy. Hedischarged his gun into one zombies chest just to give Hershel a hint that they are actually dead and can't be cured. And then he opened the barn...
Zombies execution has begun and that was awesome!
And when the sooting stop the great culmination(and the greatest spoiler) came out of the barn. Every one was speechless and didn't know what to do. Sophia is a walker now!
And Rick has approved his position as leader and made a tough decision. He came forward and shot down poor thing.
Ricks character is about to transform. Shane is about to go crazy. Hershel is about to get desperate. Dale is about to tell truth about Shane. So every about is gonna end in the second half of the season!
But now all hopes, all searches, all easy decisions are pretty much dead already!
