It is the big night of Lori and Bobby's anniversary party at the SS Aqua Voyager dining room where both families come together.
Luna is in the middle of doing karaoke on the stage.
At the Louds' side, Lincoln says to his siblings "Guys, you'll never believe the stunts I did with Ronnie Anne on the flowrider. It was like I was some sort of surfing acrobat."
"That's nothing compared to my sky dive which splashed everyone. Then, I got banned from the pools for the rest of the trip." said Lynn.
"At least you had a slightly worse faith, I got sunburnt all over and I still see red on my skin." said Lola.
"Good thing I packed up 2 gallons of aloe vera for everybody. That aloe vera bath should've soothed that overheated tan of yours. Your welcome." said Lisa.
"Well, at least her skin will heal up. I look like an unfinished piece of firewood. What is this, shop class?" said Mr. Coconuts.
Leni is still on edge while sitting next to Lori.
"OK, Leni. You are in deep water here. You better not say anything about yourself and Bobby. Matter of fact, you better not say anything in general." said Leni's mind.
Lori glances at Leni and looks concerned.
"Are you OK, sis? You've literally been feeling tense all day." said Lori.
Leni doesn't say anything and looks away frightened.
Then, she ends up sighting Bobby at the Casagrandes' side of the dining room.
She gets more frightened and covers herself with a table cloth.
"Leni? What's gotten into you?" asked Lori.
But Leni still won't say anything.
Bobby looks at what Leni's doing, and feels a little worried.
"Oh, no. I hope she doesn't spill the beans." said Bobby.
"Spill the beans about what?" asked Ronnie Anne.
"Uh... these beans." said Bobby while taking a dish of beans from the Flip and spills them.
"Oops. Guess I done that myself. Hahahahahahaha." said Bobby.
"Hey! Spill your own beans, bozo." said Flip before picking up the beans himself.
Meanwhile, Carl spots Melody talking to Brock.
"*gasp* There's that stewardess again. Better make my move." said Carl before slicking back his hair and wearing sunglasses.
He gets off his seat and walks toward Melody.
"Hey there, babe. Mind if we share this dance?" said Carl in a fancy tone.
Melody laughs and says "Oh, you've gotta be the sweetest kidder around. But I can share this candy bar with you if you like."
Melody gives half a candy bar to Carl as he gets disgruntled from his rejection.
"Thank you, ma'am." contemptuously said Carl.
"Ha! Rejected again, huh?" said Sergio while still being disguised.
"Where've you been, Sergio? Have you blown your cover yet?" said Carl.
"Relax. I remained undetected. And a little full. I might not able to eat some more." said Sergio before seeing the buffet fill up again.
Sergio gets so intrigued that he says "Never mind. Time to eat up again."
He races back to the buffet and eats more food, with Brock looking on.
"I know there's something off about him. Only a matter of time." said Brock.
Meanwhile, Luna finishes her karaoke song on the stage.
"Good night, Aqua Voyager." said Luna while giving peace signs and walking off.
Melody goes up to the stage and announces "A big hands up for Ms. Luna Loud, everyone. Now, first off, I like to welcome two families who've come together for such a momentous occasion. Bobby Casagrande and Lori Loud are celebrating the anniversary of the first encounter together. And they asked to come up onto this stage for something special."
Bobby and Lori head up to the stage.
"Thanks, lady. And thank you, Louds and Casagrandes, for literally joining Bobby and I on this totes amazing night." said Lori.
"And to celebrate, we're gonna be singing a duet." said Bobby.
"Hit it, Boo-Boo Bear." said Lori as Bobby starts playing his guitar.
(Bobby)
You are the mind to my soul
You keep my heart from holes
You are the ying to my yang
You unlock my keyhole
(Lori)
You are the root to my plant
You are the eater to my ant
You were the chosen one
You fill my life with enchant
(Lori & Bobby)
Te quiero, mi amor
You're what I've longed for
Querida, mi compañera
So unique as mascara
Te quiero, mi amor
Our love, like nothing before
Forever glued in two
I love you
(Bobby)
I was a loner
Until I caught your eyes
Their magnifico like yourself
An angel sent from the skies
(Lori)
Literally, I'm adored
By the great presence of yours
I feel this love grow
And I want it some more
(Lori & Bobby)
Te quiero, mi amor
You're what I've longed for
Querida, mi compañera
So unique as mascara
Te quiero, mi amor
Our love, like nothing before
Forever glued in two
I love you
(Lori)
No, you
(Bobby)
No, you
(Lori & Bobby)
No, us
Te quiero, mi amor
The song has ended with everyone giving a standing ovation.
Lynn Sr. cries from the sight, and so does Frida.
"Ugh. Cheesytown, population: them. Am I right?" said Lynn.
Everyone else glares at Lynn.
"I respect their sentiment." humbly said Lynn.
At the stage, Bobby says to Lori "You know, babe. Singing that song made me realize somthing. We should be forevered glued in two, because..."
Bobby gets down on one knee.
"Wait. He's not." said Ronnie Anne.
Bobby takes out a small box.
"He really isn't." said Maria.
The box opens, revealing an engagement ring.
"Madre Mia! He is!" said Arturo.
"Lori Loud. Will you marry me?" proposed Bobby.
Lori heavily gasps for 5 seconds and shouts happily "LITERALLY!"
Both the Louds and the Casagrandes freak out after witnessing a surprise proposal.
There's an even bigger standing ovation for Bobby and Lori as they both share a kiss.
"I love you, Bobby." said a tearful Lori.
"I love you too, Leni." incorrectly said Bobby.
After that misleading, Lori shouts "LENI?!"
"LENI?!" followed the Louds.
"LENI?!" followed the Casagrandes.
"LENI?!" followed Sergio who by the way inadvertently reveals himself.
"SERGIO!" shouted Carl.
"SERGIO?!" followed Rosa and Hector.
"BIRD?!" shouted Brock who snuck up behind Sergio.
"VAMOS!" shouted Sergio before flying away and having Brock chase him.
"Leni." said Leni in a fearful manner before slowly lowering herself under the table to hide.
Lori gets so angry suddenly that she marches down toward Leni, aggressively rips off the table cloth and grabs Leni by her dress.
"Leni, do you mind explaining to me why Bobby, the one and only love of my life and fiancé for a couple of seconds, just called me by your name?" asked a daunting Lori.
Leni shivers from fear and sweats a lots as if she was about to confess against her will.
Bobby signals her not to, but Leni was so scared by Lori's frightening glance that she screams...
"BOBBY AND I KISSED!"
What she said can be echoed all over the cruise.
Everyone on board gasps.
"They did what?!" exclaimed Flip.
Lori was paralyzed with shock that she ends up letting go of Leni.
"Uh... babe. You alright?" asked Bobby.
Lori starts shaking with anger, turns around and shouts to Bobby at a furious tone "DON'T. YOU. BABE. ME!"
"How dare you kiss another Loud girl? How dare you?!" she wailed aggressively to Bobby.
"It wasn't my fault, babe. It was an accident. Honest." said Bobby.
"Honest? Honest?! You mean like when you said we'd be forever glued in two?! Or when you said I was an angel?! Or when you said I was your amor?!" angrily said Lori.
"Yeah." said Bobby.
Lori grabs Bobby's hand and puts the ring on it.
"We are literally through. FOREVER!" cried a distraught Lori before storming out.
"Lori?" said Leni.
Lori storms close to Leni and says in a very quiet and merciless tone "You stupid, two-timing idiotic girl. You are literally dead to me."
Leni gasps as her heart breaks.
Lori angrily storms out of the restaurant altogether.
Bobby stares at the engagement ring with utter sadness.
He walks through the Casagrandes tearfully.
"Mijo?" said a concerned Arturo.
"Roberto?" said a concerned Rosa.
Leni becomes even more tearful as she also walks out of the restaurant knowing that she has shattered her friendship with Lori and destroyed the love of her sister and Bobby.
"Leni?" said Rita as the all the Louds look concerned.
Melody walks up the the stage and says "Uh, apologies for that serious episode. Uh, why don't we put this heartbreaking disaster behind us and continue with the karaoke."
"Ooh-wee. That's my queue. Hit it!" said Flip as he starts singing.
(Flip)
Everybody drink the Flippy Flip
Yeah!
Come on, now, take a sippy sip
Yeah!
You know to make that straw drip
Yeah!
So everybody do the Flippy Flip
Yeah!
He sees that nobody is in the mood to be entertained by his performance.
"Oh, come on! I paid big money to sing in front of you people. What a lousy reception." said Flip.
