[[wysiwyg_imageupload:1023:]]The Walking Dead showrunner, Glenn Mazzara, recently answered some fan questions that included the reveal of an alternate season two ending, as well as the reason why Lori reacted the way she did upon learning the death of Shane.
The alternate ending saw the group find the prison, instead of the camera just zooming out revealing the prison in the distance.
"We actually thought of an alternate ending [to Season 2] where they were on the road and attacked by zombies and fled toward the prison and found the prison that way. Given the extent of the mayhem already in the episode, we decided to end the Finale on a more character-based beat. We thought about the story we were telling, and decided that if Rick was the central protagonist of Season 2, it was really important to end on an internal change in that character."
Now some fans have commented as to the curious behavior of Lori in the season finale. When Rick told her that he had killed Shane, she became upset. Just why was that? Mazzara fills us in.
"Lori loves Rick, and she has recently realized that she does indeed love Shane. She almost said so in "Better Angels." She decides to take action by talking to Rick, so when Lori is horrified by Rick's confession, yes, she is upset a man she loved was killed but more importantly, that man was killed by another man she loves and she was a catalyst... She is horrified by her own culpability and is projecting that self-hatred onto Rick."
We also get a tease about that enigmatic helicopter that led to the forming of the zombie horde and eventual downfall of the farm, as Mazzara states it is not that last we will see of that.
"Let's just say that it's not the last we've seen of it. There's a story behind that helicopter."
