The Walking Dead: The Complete First Season

Chapter 3 starts out with Clementine asking you questions regarding the event. Some of the dialog is just plot progressing, but when you get to the questions below be aware. 

"Did you kill it?"

1. Something else did. - Clementine will remember this.
2. I don't know. I think so. - Clementine will remember this.
3. Yes. - Clementine will remember this.
4. . . .  - Clementine will appear scared.

After more dialog you will come up to the following untimed question:

"What should we do now?" 

1. Look for help, before it gets dark. - The next series of gameplay will take place in the light with a brief PANIC ATTACK.
2. Get out of here once the sun goes down. - The next series of gameplay will take place in the darkness with NO PANIC ATTACK.

Either decision has no massive consequences. If you choose the daytime you will meet Chet and then proceed to Hershel's farm, if you choose the night you will meet Officer Andre instead since Chet will be a zombie. 

- Option 1: Leaving before the sun goes down -
Upon trying to open the gate Clementine will express her worries about leaving without her parents. Timed question:

"What if my parents come home?"

1. They won't. Let's go.
2. I won't leave you alone.
3. I don't know.
4. . . . 
   (All answers lead to unique, but non-altering results.)

Talk to the men and run through the dialog, choices do not matter here, and will lead to the following question which influences opinions later on:

"How about you help us clear the way and we'll take you and your daughter to my father's farm. It should be safer there."

1. I'm her neighbour. - He will notice and respond to what you said.
2. I'm her babysitter. - Shawn thinks you are the babysitter.
3. I'm just some guy. - He will notice and respond to your comment.
4. . . .  - Shawn comes to his own unique conclusion.

After your choice you will now begin the short PANIC ATTACK where you must move the car. After you move the car the attack will be over. Enjoy the cut scene and move into Chapter 4 (If you do this skip over Option 2 guide). 

- Option 2: Leaving after the sun goes down -
Upon exiting the house you are shot at and have this timed question:

"Are we going to die?"

1. I don't know. - Non-altering response.
2. No. - Clementine calms down a bit.
3. They're after me, not you. - Non-altering response.
4. . . .  - Clementine gets very upset.

The two men will shout out to you and you must respond:

"Stay down! Georgia State Patrol!"

1. OK! - They hear and respond to that.
2. We're friendly! - They hear and respond to that differently.
3. I'll come quietly! - They hear and respond to that in a new way as well.
4. . . .  - They shoot the car but nothing plot-altering occurs.

Once they realize you are humans and not zombies you will be presented with a timed response:

"How about you help us find our buddy and we'll take you and your daughter to my father's farm. It should be safer there."

1. I'm her neighbour. - He will notice the response.
2. I'm her babysitter. - Shawn thinks you are the babysitter.
3. I'm just some guy. - Shawn notices and reacts to this.
4. . . .  - Shawn draws his own unique conclusions.

Their friend Chet appears in zombie form and they all run to the car. Off to Hershel's farm we go!
