Next day, at the Loud House...

Luna and Luan were at their bedroom, with Luna playing some sick tunes on her guitar while Luan rested on her bed, looking strictly at the ceiling as she remembered the distraught look Mrs. DiMartino had on her face as she and Luna walked back home after their visit.

"Yeah! Brand new record!" Luna exclaimed as she finished player her music. "Hey Luan, something tells me that game Giggles showed me really helped me with my shredding, what do ya think?"

"Mom... I didn't knew I hurt you that much..." Luan remarked to herself, grabbing her forehead as she started shedding tears. "If only I had known earlier-"

"Love?"

Luan jumped up-hitting the ceiling in the process-and turned around to see Luna looking at her with a worried look. "I just asked you if my shredding had improved thanks to Giggles. Her game was shredding-related, after all."

"Oh, uh, y-yeah, you definitely improved!" Luan answered before laying on her bed and turning away from Luna. "N-Now, please leave me alone, I have to think about something."

"Were you crying just now?" Luna suddenly realized, and blurted, causing the comedian to flinch. "Luan, if there's something that's bothering you, then you don't need to hide it from me, you can tell me what it is and I'll help you. I mean, you told me your real identity, so I can assure you whatever revelation you have for me-"

Luan turned back to look at Luna with a tearful face, "DiMartino's my mother."

Luna's smile slowly turned from "happy and confident" to "wait what?" in a couple of seconds, followed by the musician blatantly stating, "W-Well, that's something I wasn't expecting to find out this soon."

And then she realized what that meant. "Wait, doesn't that mean Giggles is your sister, then? And your real sister, at that?"

Luan facepalmed. "Great, another thing to worry about!"

"Sorry for bringing that up, I really need to watch what I say more often," Luna chuckled, scratching the back of her head. "Now, I have to ask, why didn't you tell me DiMartino was your mother yesterday?"

"I neither had the time, nor the heart to do it," Luan sighed. "You looked so happy after the visit, and my moment with DiMartino was really upsetting, so I wasn't feeling like bringing it up. Just like how I wasn't feeling like worrying about the Chuckles impostor-"

"There's a Chuckles impostor?" Luna tilted her head, only to get an "you can't be serious" glare from Luan. "Oh right, the one from the factory! Now I remember! And now that you mention it, she did say she had something in store for Royal Woods."

Upon hearing that, Luan suddenly got an idea, and smiled. "Luna, could you please get out of the room? I need to talk to myself."

Luna tilted her head and frowned. "You mean as in-"

"No, not as in literally talk to myself like some crazy person," Luan sighed. "I mean as in, let me rest so I can go to my mind, and talk with Chuckles."

"Are you sure that's a good idea, love?" Luna brushed Luan's hair. "I mean, last time you met her, it was in a nightmare that required you to sleep with me to deal with it."

"Even if our meeting is unpleasant, I still have things to discuss with her, specially now that we brought up the impostor Chuckles," Luan put on a reassuring look. "So now, if you could please leave me alone, I'd appreciate it."

Luna nodded with a slight smile, then promptly obliged and left. Luan fell asleep soon afterwards, and when she "woke up," she found herself sitting on a chair, with a table with a cake and some dessert on it. And also a couple of fireworks next to the cake.

"You remember now, don't you?"

Luan turned to the source of the voice, and saw none other than Chuckles-dressed like Luan's former clown self-staring at Luan with extreme prejudice. Not that the comedian was affected. In fact, she seemed rather... Stoic.

"This is the birthday party where you ran away from your life as Luan DiMartino," Chuckles remarked as the table morphed to now only hold the fireworks, with the cake and dessert suspended in the air. "Our birthday party, according to mom."

Luan just nodded, and Chuckles grabbed the fireworks.

"There were two variations of fireworks available, a normal one, and a facial one," Chuckles showed the fireworks; the normal one was red, while the facial one was yellow. "We meant to use the normal one in order to show off, and the super one would later be used to create our face in fireworks as the party's finale. Sadly, we picked the wrong one."

Luan nodded once more, though with notable regret.

"So, we decided to try the "fire breath" trick."

Chuckles threw the facial fireworks in the sky, then blew some fire onto it, causing it to blow up into a fireworks version of Luan's face. And in that instant, memories flashed through Luan's head, which were shown in the background:

First, Luan-back then Chuckles-leaped back in fear and crashed through the table, causing the cake and dessert to fly off and land on the ground. And not only that, some of the firework dispersed... And hit the normal fireworks.

Next, Luan watched as the normal fireworks activated and went off flying at random, burning a bit of the grass but, miraculously enough, not hurt any of the partygoers. However, a younger DiMartino still decided to go back home and take out a fire extinguisher.

Finally, as the fires were being put out, Luan watched all over the place to see her mistakes: Crying kids, the ground burning, cake and desserts destroyed and on the floor, and basically, one birthday party. Her birthday party ruined. And it was all her fault. And on the verge of crying, the clown girl got up, ran away, and the rest of the memories went off as normal until the background suddenly turned back... To the DiMartino house backyard.

"Is that how it happened?"

Luan turned back to Chuckles, who was back to her "Luan but with two ponytails" look. She still had a stern look at her new self, but there was some slight worry underneath it.

"Yeah, I remember now," Luan answered without hesitation.

"And what does this tell you, Luan Loud?" Chuckles inquired. "What does this tell you about the consequences of what you've done?"

Luan frowned. "Ever since we left... Ever since I left, I thought mom would just disown me. And yet, she kept my room exactly the same as how it was, for so many years."

Chuckles rolled her eyes. "It's like what I've been telling you, us running away did far more harm than good. Not only for us, but for our original family."

Luan remained silent as Chuckles continued:

"Listen, first, an impostor of our identity comes out of nowhere and threatens to do something horrible this April Fools Day, and now, you have seen what mom did after you ran away: She held on hope you'd return, only to see you had thrown away your original identity."

And then came a question:

"What more do you need to see before you're convinced to try and make ammends? Before you decide to stop being a Loud, and return to being a DiMartino?"

Luan stood up, and with a confident tone, she answered:

"Nothing."

Naturally, Chuckles was confused, "Excuse me?"

"I've managed to get my thoughts together," Luan shook her head. "I've done everything wrong up to this point: Instead of things getting better because I ran away, they got worse. Instead of mom being angry at me for ruining my own birthday party, she's both angry and devastated because not only did I run away, but I was adopted by an entirely different family! And as if that wasn't enough, there's a copycat of my old identity running around who's planning something on-"

Luan and Chuckles exchanged looks as they stated in unison:

"April Fools Day."

The duo exchanged looks, and soon enough, Luan nervously rubbed her arm while Chuckles... Smiled. And it wasn't a smug or malicious smile, but a confident one.

"So... C-Chuckles, I know you prefer to-"

"Say no more. I'll accept the truce."

Upon hearing her original self say that, Luan turned to look at Chuckles, arms folded and with a confident grin, giving her a thumbs up. "Why take you over and try ruin your reputation on April Fools Day, when we can reveal the faker's identity and return to the world in the most glorious fashion?!"

Luan looked at the ground with doubt. "But... Is it necessary to reveal who we really are?"

Chuckles put a hand in Luan's shoulder. "We both know the only way to stop our faker from continue stealing our identity, is for us to reveal who we really are, then unmask her for the world to see. It may be hard, it may be difficult, but we still have to try."

Luan looked back up to see Chuckles giving her a reassuring smile. Upon seeing that, Luan smiled for a moment before her smile turned into a confident smirk. "This April Fools Day..."

The pair shook hands, and finished in unison:

"The joke will be on her!"
