ENTERTAINMENT WEEKLY: What can you tell me being on set for this climactic scene?

SCOTT M. GIMPLE:I remember the day building and building with emotion.
Rick wanted to be the guy who would look for the little girl who was lost.
Shane was the realist who didnt.

It was just a remarkable performance by Jon Bernthal.
I had designed the script like an episode ofSeinfeldin a lot of ways.
All of these disparate stories crashing together at the end.

Meanwhile, they find out about this threat in the barn right under their noses.
But then everyone loved the payoff.
Thats one of the lessons I learned: The audience wants to know things sooner rather than later.

In that case, I think if they knew sooner it would have been denied some of the impact.
The audience, in some ways, had to suffer along with the characters.
The audience felt it more because they had put in that time on that search.
It was a great experience doing that.
Why is Rick the one who has to put that bullet in Sophia?
Because it was about him changing.
Because it was about him accepting some realities.
So many seasons are about Ricks transformation, but this was a big one.
He was the one strong enough to do this.
Nobody else stepped up to do it.
Its always a big day on set when its someones death scene.
How was that for Madison Lintz, who played Sophia?
Thats a lot for a young girl to play a zombie and then get shot down?
She was remarkable and was an incredible pro.
In many ways she was and is an old soul.
Madison had to come out as a Walker essentially on stage.
It was a very strange introduction as a Walker.
It was so theatrical that she basically stepped out from behind the curtain.
She came out and it was horrible, so she did her job incredibly well.
The acting in that scene was heartbreaking.
Madison absolutely did that.
For seven episodes to crash into this 10 seconds, its an incredibly important moment.
It was one of the defining moments of the show.
