While Gru and Lucy were at the AVL, the girls were in the front yard of Gru's house.

Margo: Well Gru got Lucy's job back.

Edith: Yeah. This is pretty good. Things can only get better.

Agnes: Yeah.

Margo: What can happen?

What the girls didn't know was that Scarlet, Vector, El Macho, and Herb were hiding in a bush. There was a potion in Scarlet's hand

Scarlet: Okay. Here's the plan. I will take this potion and turn into Gru. You two will make the minion serum.

Vector: Got it!

El Macho: You can count on us. Come on Vector.

Vector and El Macho left.

Herb: What do I do?

Scarlet: You will dress up as Balthazar and sing The Lady In Red.

Herb: But I want to do something.

Scarlet: You are doing something. You're being Balthazar.

Herb: But I want to do something that has something to do about the plan.

Scarlet: Yeah who cares? Now put this on and sing The Lady In Red.

Herb: But I don't know the song.

Scarlet: Well learn it!

Scarlet took the potion and turned into Gru.

Herb: Are you Scarlet or Gru?

Gru: It's me Herb! Now start practicing.

The fake Gru walked over to the girls.

Agnes: Hey Gru.

Gru: Hey Agnes. Margo, Edith, and Agnes, follow me.

Margo: Okay.

The fake Gru took the girls to Scarlet's Castle.

Edith: Uh Gru?

Margo: Why are we here?

Scarlet took off the Gru costume.

Scarlet: Because I'm not Gru. I'm Scarlet Overkill!

Agnes gasped.

Margo: What is happening?

Edith: Oh my god. Scarlet planned this!

Scarlet: That's right!

Edith: Why are you doing this!?

Scarlet: Your father ruined every plan that I had!

Margo: Well it's not his fault that you're a villain.

Scarlet: It doesn't matter. This ends now! El Macho!

El Macho: Ready?

Vector: You bet.

Vector and El Macho threw the yellow serum on the girls and they turned into minions. Margo looked at her hands.

Margo: Oh no. Um Edith, Agnes, I think something's wrong.

Edith: Something is wrong. Look! We're minions!

Agnes gasped.

Margo: How is turning us into minions going to stop Gru from ruining your plans!?

Scarlet: It's not going to. It's just going to make you miserable!

Scarlet used her Lipstick Taser on the girls and stole Margo and Edith's phones.

Scarlet: El Macho, destroy these!

El Macho: Happy to.

El Macho took the phones. The girls opened their eyes.

Agnes: What was that?

Scarlet: Never mind! You will be stuck here forever!

Margo: Not if I can stop this!

Margo looked for her phone, but she couldn't find it.

Margo: I can't find it!

El Macho broke Margo's phone and gave it to Scarlet.

Margo: Oh where is it?

Scarlet: Looking for this?

Scarlet was holding the broken phone and she showed it to Margo. Margo gasped.

Margo: But I need that! How did this happen!?

Edith: It's alright Margo. I have mine.

Edith put her hand in her pocket, but she couldn't find her phone either.

Edith: Huh? Where's my phone?

Vector had it. Then he dropped the phone in apple juice.

Edith: Vector! Great.

Agnes: Now we don't have a phone.

Margo: What are you going to do to us?

Scarlet: I've got a plan. You three are bait. When Gru and Lucy find out that you're gone, they will come here and that will give me the chance to destroy Gru, turn Lucy to the dark side, and kidnap Balthazar!

Vector: Are you kidding me?

El Macho: 80s guy again? Scarlet, we talked about this obsession.

Herb: I thought we moved on.

Scarlet: Well we didn't. Now get back to work and learn that song!

Herb sighed.

Herb: I hate being Balthazar's body double.

Meanwhile Gru and Lucy walked into their house.

Lucy: Woo! You did it Gru!

Gru: Yeah. Girls, I'm home.

There was silence.

Gru: Hmm. That's weird.

Lucy: Girls?

Dru: Hey brother.

Gru: Dru, have you've seen the girls?

Dru: No. I haven't. The last time I saw them, they were outside.

Gru gasped.

Gru: Oh no. The security camera. Come on!

Lucy: Okay.

Dru: Wait for me!

Gru, Dru, and Lucy ran outside. Gru grabbed his laptop and hooked it up to the security camera.

Dru: Hey look. There you are with the girls.

Gru: What?

Lucy: But weren't you at the AVL?

Gru: I was. How can I be here when I was at the AVL?

Dru: Maybe there's two of you.

Gru: Unless it was Scarlet disguised as me. That's it! Scarlet was here and she kidnapped the girls!

Balthazar ran outside.

Balthazar: What!? She's here!?

Gru: No. She kidnapped the…

Balthazar: I've got to hide! I'll be in my room!

Balthazar ran to his room.

Gru: No. She's not...never mind.

Dru: Well we know where they are.

Gru: Yeah.

Gru sighed.

Lucy: You okay Gru?

Gru: Dru, you were supposed to keep an eye on them! I can't even trust you for that!

Gru groaned.

Dru: Sorry brother.

Gru: Why did you screw this up?

Dru: I was doing fine watching them until I got a fly bite.

Gru: Yeah. Like a fly bite will stop you from watching the girls. Great excuse.

Gru folded his arms.

Dru: No. I mean it. Look at my leg.

Dru rolled up his pants and Gru saw Dru's bite.

Gru: Oh! Okay. I see it. Cover that before I throw up.

Dru: Okay.

Dru coved his bite.

Dru: See?

Gru: I believe you. Now I've got to save the girls. Lucy, you're coming with me.

Lucy: Got it!

Dr. Nefario and Fritz walked outside to Gru, Dru, and Lucy.

Dr. Nefario: Hey Gru. What's up?

Fritz: And why is Balthazar hiding in our bedroom?

Gru: Scarlet kidnapped the girls and Lucy and I are going to save them. And Balthazar though that Scarlet was here. Dr. Nefario, help Dru.

Dr. Nefario: Why? What happened to Dru?

Gru: Fly bite. Let's go Lucy.

In Scarlet's Castle, the girls were in a cage.

Agnes: What do we do now? We'll never see Gru ever again!

Margo gasped.

Margo: I've got it! Edith, your pranks!

Edith: You're right! What was I thinking? Okay Scarlet! Let us out or I'll prank you!

Scarlet: No.

Edith: Alright. You asked for it. Pranks coming up!

Scarlet: Go for it.

Vector: What!?

El Macho: Why would you let her? She'll ruin it.

Scarlet: Not this time.

Scarlet laughed. Edith looked in her pocket, but she didn't see her pranks.

Edith: What? Where are they? I can't find my pranks.

Scarlet continued to laugh.

Scarlet: Looking for these?

Scarlet held up a bag filled with pranks. Edith gasped.

Edith: Who, what, where, when?

Margo: You forgot why and how.

Edith: How did you get those?

Scarlet: I remember the last time I kidnapped you!

Edith: Alright you listen to me Scarlet! Give me those back or you'll be sorry.

Scarlet: You don't scare me little minion. Minions can't threaten me, but I can threaten them!

Edith sighed.

Edith: Thanks Margo!

Margo: Whoa, whoa, whoa! What did I do!?

Edith: You're the one who told me to use my pranks!

Margo: Oh really.

Edith: Yeah!

There was an argument between Margo and Edith. Meanwhile Gru and Lucy were in the Grumobile and they were going to save the girls.

Gru: I hope the girls are okay.

Lucy: I'm sure their fine.

Gru: Call Margo.

Gru took out his phone and threw it to Lucy.

Lucy: Okay.

Lucy called Margo, but due to El Macho breaking the phone, the number was not in service.

Lucy: No.

Gru: Take the wheel.

Lucy took the wheel and gave Gru the phone and Gru called Edith, but he got the same message that Lucy got.

Lucy: Well?

Gru: No. Oh no!

Lucy: Hey. Felonius, calm down.

Gru: Sorry.

Lucy: We'll find them.

Gru: You're right.

Lucy: We just need to stay positive.

Gru put his phone away, grabbed the steering wheel, and started driving. At Scarlet's Castle, Margo and Edith were still arguing and Scarlet had it.

Scarlet: Enough! That's it! If I hear three more peeps from any of you, you will never see your father ever again!

The girls were silent. Agnes looked at Margo. Margo started whispering.

Margo: Don't worry. I'll find a way to get us out of here.

Scarlet: Oh and one more thing. Whispering counts as talking! That means you only have two more peeps left until Gru's gone forever. So use it well my little minions.

Edith: Oh that's it Scarlet.

Margo mouthed the word no.

Edith: Hey! Miss Crazy! You can't keep us locked in here like this! We are not prisoners! You're the one who's despicable, not Gru!

Scarlet: Ah! That's two! I knew you kids wouldn't stay quiet. And yes, I am despicable. Now all I need is little tiny Agnes to say something and it's goodbye to Gru.

Margo mouthed the words stay strong to Agnes.

Scarlet: Finally! My plan is not going to fail this time!

El Macho: I don't know about that Scarlet.

Vector: This plan sounds great, but will it succeed?

Herb: Yeah.

Scarlet: Are you three doubting me!?

Vector and El Macho: Yes.

Herb: No.

Scarlet: Don't doubt me Vector and El Macho. This plan will not fail! I've got Gru right where I want him. Do you two understand me!?

Vector and El Macho nodded.

Scarlet: Good.

Agnes looked at Margo and Edith. They shook their head at her, but Agnes couldn't stay quiet.

Agnes: I can't take it! Please don't kill Gru! I'm begging you!

Scarlet laughed.

Margo and Edith: Agnes!

Scarlet: I knew it. You wouldn't stay quiet for fifteen minutes!

Margo: Please Scarlet. Give us another chance.

Edith: We promise we won't ruin it this time.

Scarlet: I had it with your little games girls and I will not regret this! When your father comes, get ready to say your goodbyes.

Each girls had a different expression. Agnes was crying, Edith was ready to fight, and Margo was thinking of a plan to escape.

Agnes: We have to get out.

Margo: I know. I'm thinking of an escape plan.

Scarlet: There is no escape girls. You're stuck in a cage. How are you going to get out? The answer is simple, you won't. Herb, El Macho, take the cage with the girls and put them in the storage room.

Herb: You want us to put live minions in a storage room?

Scarlet: You got a problem with that?

Herb: No.

Scarlet: That's what I thought. Now do what I say!

El Macho: Yes ma'am.

Herb and El Macho took the girls to the storage room downstairs in Scarlet's Castle.

Vector: What do I do?

Scarlet: Create a deadly weapon!

Vector: Roger that Scarlet.

Gru parked the Grumobile.

Gru: We're here.

Lucy got out of the car. Then they both ran into the castle.

Gru: Shh! Over here.

Lucy: Okay. Now where could they be?

Gru pressed a button on his phone and he actually had a locator chip that can locate the girls.

Gru: I've got a chip on them.

Lucy: Uh Gru, now is not the time to talk about food.

Gru: Food? No. It's a locator chip.

Lucy: Oh. Oops.

Gru: This way! I'm picking up a signal in the storage room!

Lucy: Then let's go!

Gru and Lucy went into the storage room.

Gru: Wow. More boxes.

Lucy: I know. Where could they be?

Margo sighed.

Margo: So much for getting out. This is all my fault.

Edith: No kidding!

Margo: I'm so sorry.

Edith: It's fine.

Agnes: but now Gru will be gone. I'll never see him again!

Gru saw a security camera. He took his Freeze Ray out and froze the camera. Margo, Edith, and Agnes saw the frozen camera.

Margo: What was that?

Agnes: Look! The security camera is frozen!

Edith: Then that means…

Gru: Girls!

Girls: Gru!

Gru: Shh, shh, shh, shh. I'm going to get out of here.

Gru opened the cage and the girls hugged Gru. Lucy waved. Then Gru took out the blue serum that will turn the girls back

Margo: Thanks Gru.

The girls took the serum and turned back into humans.

Gru: Let's go!

Lucy: Come on!

But before they can escape, Scarlet caught them.

Scarlet: Well, well, well. Nice try, but you failed!

Gru: Yeah right.

Gru froze Vector's foot making Vector trip, causing a lot of problems. When he tripped, he dropped his weapon and the deadly weapon sprayed Gru's Freeze Ray.

Gru: Come on!

Gru grabbed the Freeze Ray, but he didn't know that it was sprayed by a deadly weapon. Gru, Lucy, and the girls left. Vector smiled.

Scarlet: Did it work?

Vector: Yes.

Scarlet: What did it hit?

Vector: The Freeze Ray.

Scarlet: Perfect.

Scarlet laughed.
