Summary: Adrien, Felix, Marinette, and Bridgette decided to fool everyone by switching appearances in which lead to Lila's lies being exposed.
~~~~~
Marinette and Adrien's cousins are known for each other in London and they decided to visit Paris in April Fools. Marinette and Adrien are at the bakery to help Marinette's parents when the door opens.
Marinette: Welcome to the b-
Marinette gasped dropping the box in the process. Adrien looked up and gasped as well.
Marinette: Bridgette?
Adrien: Felix?
Bridgette: Marinette!
Marinette hugs Bridgette.
Felix: Bridgette wants to come with me so she could visit her cousin. It's good to see you too, Adrien.
Felix hugs Adrien and Adrien hugs him back. After they help in the bakery, Felix checks on his phone what day is today.
Felix: Hey guys, do you know what day is today?
Marinette looks at her phone and she has realized it.
Marinette: You mean...
Felix: April Fools!
Adrien: Oh yeah. Today is spring, meaning it's April Fools.
Bridgette: So, that means we're going to prank people?
Felix: Oh, yes. With a twist.
The cousins' faces lit up with the idea.
Adrien: Oh~ this is going to be funny.
Marinette: But first, we want to inform you two about something.
Bridgette: And what is it?
After Marinette and Adrien explained the situation, Bridgette went rage at how Lila threatened her cousin like that, and Felix was disappointed.
Bridgette: This girl needs to be down.
Marinette: I agree, meaning we could prank her and our so-called friends.
Bridgette chuckles evilly as Felix gets scared with the face.
~~~~~
The cousins are now in place. Marinette and Adrien wear their cousins' clothes and Bridgette and Felix in vice versa and now separated into several places. Felix as Adrien was scheduled for the photoshoot with Lila which made him disgusted. Bridgette as Marinette was at her cousin's home helping Marinette's parents in the bakery. Meanwhile, Marinette and Adrien as their cousins went on an ice cream date at Pont des Arts. Almost everything is according to plan, not even Lila realized who she hangs out with. When "Adrien's" photoshoot was over, his so-called friends came by as Lila clutches Felix's arm.
Alya: Hey Lila, Hey Adrien!
Nino: Hey dudes.
Lila: Hello guys!
Felix (Adrien): Hey.
Nino noticed his behavior.
Nino: Are you okay, dude? You don't feel energized.
Felix (Adrien): Oh, I'm good. I'm just not in the mood today.
The group is talking a lot when Felix spotted Marinette and Adrien entering the park.
Felix (Adrien): Felix!
Adrien (Felix): Oh, hey Adrien.
The duo approaches them.
Lila: Adrien, you know him?
Felix (Adrien): Yeah. That's Felix. He's my cousin.
Alix: Man, I didn't know you have a cousin.
Alya: But, why is Marinette here?
Marinette (Bridgette): Pardon?
Alya: What are you doing here, Marinette?
Adrien grips Marinette to get close to him.
Adrien (Felix): I'm sorry, but her name is not Marinette.
Felix (Adrien): Yeah. Her name is Bridgette, Felix's girlfriend.
Kim: Uh, are you sure that's Marinette? Because the other Marinette was just entering the park over there.
Kim points at Bridgette who's entering the park holding a box of pies.
Bridgette (Marinette): Hey Adrien, Bridgette, Felix.
Marinette (Bridgette), Adrien (Felix), Felix (Adrien): Hey Mari.
The rest groans when they saw "Marinette" came.
Mylene: How come you guys know each other?
Alix: That's not cool.
Rose: Yeah! You don't belong here.
Marinette flinched a little bit worried about their prank. Bridgette noticed.
Bridgette (Marinette): Should we tell them?
Alya: Tell us what?
Adrien shrugged before giving a questionable look at his cousin who is still being clutched by Lila.
Alya: TELL US WHAT?!?!?!
Nobody answered, instead, Felix starts to laugh then Adrien, Marinette, and Bridgette earning curious yet furious looks from the group.
Alya: WHAT IS IT?!?!?!
Marinette stopped laughing to answer.
Marinette (Bridgette): Do you notice what day is today?
This earns curious looks again but Max checks the date then he turned pale.
Kim: What is it, Max?
Max: Today's April first, meaning...
The cousins laugh again before saying at the same time.
Cousins: April Fools!
Akuma Class: What?!
Lila: What?! So, does this means...
Felix: That's right. We tricked you by switching ourselves.
Lila felt disgusted when she released Felix, and she felt guilty for not being with Adrien this whole time. Adrien laughs again when he saw Lila's expression.
Adrien: You should see your face, Lila!
Lila was now embarrassed at this point.
Lila: But, how could be possible if I knew it's you or Felix?
Nino: What did you do when we have Felix?
Adrien: Let's just say that I went on a date with my princess.
Akuma Class: Princess?!
Marinette: Oh, hush you, Kitty.
Bridgette: Can we go now? The pie is almost cold.
Marinette: Sure.
Adrien & Felix: Bye-bye.
The cousins are about to leave the park when Lila is about to attack Marinette when Bridgette grabs her hand and flung her.
Bridgette: That's for threatening Marinette in the bathroom in school!
The group has now left the place but stopped by a limo which it's belongs to Chloe as they greet her. Meanwhile, the group stands there, pale, guilty, and speechless.
Kim: I guess they fooled us good.
Kim gets elbowed in the stomach by Alix.
