[Cady and Sophie playing outside, M3GAN watching them and all around herself]
Cady: It was a time of great suffering among the Celtic tribes.
Sophie: Death, destruction, and mayhem at every turn.
Cady: Enemies approaching from every corner.
Sophie: And so it was decided that the firstborn of each leader must prove their worth.
Cady: 'Tis we, Princesses Cady and Sophie of the clan McJames.
Sophie: We will receive this challenge will pleasure, for there is no warrior we can't best, no shield we can't break, no castle we can't breach.
Cady: A long as we have our secret arrows, our trusty steed and the wind at our back, we will avenge our parents' death.
Sophie: Hey, M3GAN, check this out.
[Sophie shooting a toy bow]
Sophie: Gotcha. You're dead. M3GAN, what's wrong?
Cady: I don't know.
[the girls realize that they lost one of their arrows]
Cady: Oh, man. We lost one of our arrows.
Sophie: M3GAN, can you see it?
[M3GAN scanning, she notices the lost arrow on Celia's side of the fence; M3GAN coming out to the garden, getting closer to the fence, she is kneeling in front of it to grab the arrow, suddenly Celia's dog attacks her]
Sophie: M3GAN!!
[Sophie running to M3GAN being attacked]
Cady: Oh, man.
Sophie: Stop it! Get away from her!
[Cady running to them]
Cady: Gemma!!!
Sophie: Get off of her!! Stop it!! You're hurting her!!
Cady: Gemma! Let go!
[dog bites Cady, she's screaming]
Sophie: No!!!!
[the dog letting go of Cady's hand, M3GAN steps aside, the dog runs away, Celia coming into the yard]
Celia: Dewey?
[Sophie taking Cady's injured arm gently, Cady weeping]
Sophie: No, no. Don't worry, Cady. We'll fix it.
[Gemma running to the girls, she sees Cady's injury]
Gemma: Oh, my God. How many times do I have to tell you to keep your dog off my property!?
Celia: He wasn't on your property. You tell those two girls to stay on your side of the fence!
Gemma: I swear to God, if you don't put your dog down, I'm gonna do it for you, Celia!
M3GAN: Gemma, Cady's temperature is rising. Her wound needs to be disinfected immediately.
[Cady still weeping]
Sophie: It's okay, Cady, it's okay.
[Gemma, Cady and Sophie coming into the house]
Celia: This wouldn't have happened if you'd fixed the fence!
[time skip, evening, Gemma and the police outside her house, talking]
Gemma: Are you kidding me? Her entire arm looks like a dental mold, and you're telling me there's nothing that we can do?
A policeman: She said he was provoked.
Gemma: Provoked? Have you seen this dog? It is a monster. I'm chasing it off of my property every other day.
A policeman: Well, she said he's never on your property.
Gemma: Well, then why don't you ask her whose shit I'm cleaning off of my driveway, because it's not mine.
A policeman: Look, the dog doesn't have a history of violence. State law says he can't forcibly be put down.
Gemma: Okay, then what am I supposed to do?
A policeman: Fix the whole in your fence?
[they don't know M3GAN is watching them and listening from inside the house, she's checking Cady's state, it's not good, M3GAN decides to kill the dog; time skip, the dog sleeping in his doghouse]
M3GAN (imitating Celia's voice): Dewey! Dewey, boy! Dewey! Come here, boy. Come on.
[M3GAN clapping, she leaves a snack on the grass, the dog comes to the fence and eats a snack, suddenly M3GAN grabs and murders him]
