About the first thirty minutes would be flashbacks to the setting up of the plan. Then 10 minutes of Gareth trying to justify what they've done. And then the final 10 minutes would be a gun battle and a surprise ending.
Enjoy.
Episode 502:
Voiceover of Douglas and Rick talking about the plan.
douglas (V.O.)
Don’t go in there heavily armed, they will shoot to kill right away.
rick (V.O.)
Kinda leaves us in a dangerous spot, doesn’t it?
Douglas (V.O.)
They are thinking with their stomachs, if you go in heavily armed you might endanger not only their stomachs but their source of food also.
FLASHBACK to when Rick was hiding the duffle bag of weapons.
Rick (V.O.)
We’ll sneak in the back way, see if we can find your son and the others first. See how far we can get in before they stop us.
Douglas (V.O.)
If they see you are not a threat they will let you crawl into bed with them before stopping you. They want to give you a sense of security.
FLASHBACK to Rick and his group making their way to Gareth and his people in the warehouse with the signs and radio. The whole time Terminus people are watching them from windows and rooftops.
Douglas (V.O.)
When Regina was living there she said they kept most of their captives in a metal shipping container. They may have moved them since then.
Rick (V.O.)
Will they try to kill us when we draw our guns?
DouGlas (V.O.)
As long as you don’t shoot to kill you will be fine. The second you kill one of them they will kill you.
FLASHBACK to Rick staring at Carl who is ready to draw his gun and kill them all.
Rick (V.O.)
I will try to not to kill these sick bastards.
Douglas (V.O.)
That maybe hard because you will be the first Gareth tries to kill.
FLASHBACK to Rick almost getting shot but uses his hostage and then the group is being herded through the compound.
CUT TO: The inside of the metal shipping container as the captives hear the gunshots and start yelling for help.
DouGlas (V.O.)
Your people are being held in the train car marked ‘A’. That is where they will put you also.
RICK (V.O.)
They’ll put us together?
Douglas (V.O.)
Yes.
Rick (V.O.)
Why?
Douglas (V.O.)
Because they don’t want to seem like the monsters they are.
FLASHBACK to Rick, Michonne, Daryl, Carl, Carol and Tyreese, and Beth sitting in a room with Douglas.
DouGlas
Why are you willing to do this for us?
Rick looks around what remains of his group.
Rick
Before we do this, Douglas, I need to ask you three questions.
INT. train car ‘a’ – night
Rick and his group sit waiting in the dark. Flashlights flash through the cracks of the train car.
The large door slides open.
Guard #1
Everyone out, restroom and exercise time.
Everyone files out of the train car.
Under armed guard they are led to a bathroom in a nearby warehouse.
They all do their business and then are filed out into the courtyard around the train car.
SFX. BIRD WHISTLES in distance.
As the group walks around the train car in a circle the all look around at the guards. None of the guards seem alarmed.
SFX. BIRD WHISTLES.
The group stops walking as one of the guards shines a flashlight toward the fence.
The light shines on the trees through the fence. Slowly it scans the trees and stops on CAROL HOLDING A RIFLE READY TO SHOOT.
A single shot takes down the guard with the flashlight.
Four other shots ring out and the remaining guards are taken out.
Loud clanking comes from the fence line and the fence can be seen falling toward the trees.
RICK
GO! RUN TO THE FENCE!
Everyone runs to the fence and into the trees.
Rick, Daryl and Michonne meet up with Carol and Tyreese who hand them each guns and rifles.
RICK
You guys ready?
CAROL
Douglas’ men should be about to strike.
A group of guards come into the area.
A large explosion shakes the ground. A fireball lights the night sky on the other side of the complex.
Tyreese
We might have overdone it with that bomb.
daryl
No such thing, especially with these sickos.
The guards who just arrived turn and head toward the explosion.
Daryl
Now’s our chance.
DOUGLAS(O.S.)
Let’s get a move on.
Douglas comes out of the trees.
Douglas
Roger, get these people back to the camp. We’ll be along shortly.
rick
You sure you want to come?
DOUglas
I need to.
int. candle room – night
Candles still burn. Douglas points to a name on the ground.
douglas
That was my sister in law.
michonne
These were the sacrifices?
douglas
Yes, the inner circles were the first ones. The outer circles were the latest victims.
They all look around. There are dozens and dozens of names.
rick
We need to move.
ext. courtyard – night
The captives in the shipping containers are yelling.
Shots are fired.
Rick and the others take cover.
They pick off the guards on the roofs and make it to the containers.
They cut the locks and pull the doors open.
Another explosion lights up the other side of the compound.
Rick
That’s it. We need to get out of here.
Douglas finds his son and hugs him.
RICK
Get your people out of here, we are going after Gareth.
DouGlas
Rick, what do you mean? We have what we came for.
RICK
No, I don’t have what I want yet.
(break)
You guys ready?
Rick looks to Michonne, Daryl, Tyreese and Carol.
They all nod.
With tactical precision the five of them make their way through the facility. Killing anyone who they see who is armed. Daryl takes a wound to his shoulder but is able to continue. Michonne finds a weapon stash with their weapons in them and they take them back.
Some of the Terminus guards pin them down briefly but they manage to fight them off and they end up on the roof of one of the buildings.
As they look down in between the buildings they see walkers are swarming into the compound, drawn to the noise of the fire fight.
MICHONNE
Do we keep going?
RICK
Yes, we end this insanity.
They continue to kill Terminus guards and Zombies.
Finally they catch Gareth trying to escape with a few people.
Gareth
Rick, it’s Rick, right?
(break)
Can’t we talk about this?
RICK
You have lured people here for how long? With the promise of safety and security. But you slaughtered them when they got here.
Gareth
It wasn’t always that way. We did what we did to survive.
One of Gareth’s guards raises their gun to shoot but Daryl puts a bullet in her head.
Gareth
NO MORE SHOOTING!
RICK
Perhaps we can talk about this. But first, I need to ask you three questions.
GARETH
(a little relieved)
Anything.
RICK
How many walkers have you killed?
Gareth
Too many. Too many to count. We all have.
Rick
How many people have you killed?
Gareth
I, I don’t know how to answer that question.
RICK
How many people have you killed!?
Gareth
We did it to survive. We did it to feed ourselves.
RICK
You lured them here. You promised those who arrive survive. But it was all a lie.
gareth
Don’t judge us for what I’ve done for my people. You would do the same!
rick
Not if it meant killing innocent people. No, my people, those people you put into that train car, lost everything even after we offered innocent people a place to live, a secure place. And we lost it all. How many people have you killed?
GUARD
Hundreds! We did it to eat and we could have stopped but we survived and we would do it again.
Gareth
Let us go, we will leave here and never look back.
RICK
No, It’s too late for you.
Gareth
Let us go and I will take the rest of my people away from here.
Rick
To where? To continue to kill innocent people?
Gareth
No, we promise to never.
A woman charges Rick from the darkness. He raises his arm to defend himself and a blade hits his forearm.
Carol shoots the woman who attacked Rick.
Shots fill the air as Gareth’s people are cut down by Michonne, Daryl, Tyrese and Carol.
Rick waves for them to stop.
Examining the bodies he finds Gareth trying to crawl away.
Holding his injured arm he kneels down next to Gareth.
RICK
Why?
Gareth
We couldn’t feed them all. They came and we couldn’t feed them all.
Rick
So you ate them?
gareth
I would do it again to protect my people. You know what you have to do to survive.
rick
Yes, Yes I do.
Rick kills Gareth.
As he stands he takes a step and passes out.
ext. alexandria house – day
Tyrese and Sasha knock at the door to the house. They are carrying a basket of fruit and bread.
SAsha
Would you stop looking at me like that.
tyreese
Nope. After the prison I didn’t know when I would see you again and here we are.
sasha
Seems too good to be true.
tyreese
Still not unpacked yet?
sasha
Give me a few months and maybe I will. As much as I wanted it on the road, now I just can’t get used to it.
Tyreese knocks.
sasha
Maybe he’s still sleeping. Doc said he needs his rest.
Tyreese
Yeah, we’ll try later.
The door opens as they start to walk away.
Rick stands in the door way. Shirtless, half his face is covered in shaving cream. The other side still has streaks of shaving cream and a few spots of blood.
Sasha
Whoa! Maybe you let someone else do that.
Rick
I gotta get used to it.
Rick holds up his hands except his right hand is only a bandaged stump.
