At the Casagrande's cabin, Bobby is in his bedroom moping after Lori breaks up with him.
He lies down face first on a pillow.
Maria knocks on the door and says "Bobby? Are you OK, honey?"
"Go away. I just want to be alone." said Bobby.
Outside the room, the whole family checks in on him.
"Ay, chihuahua. I've never seen Bobby this sad since I accidentally destroyed his 3rd grade science project." said Arturo.
"I can't stand to see one of mi familia sad. Cos when they're sad, I'm said." said Frida before bursting into tears.
"Bobby, come on. Why don't you just find Lori and go talk to her?" Ronnie Anne said to Bobby.
"Just make sure you don't bump into another girl and lock lips." said Carl.
Ronnie Anne thumps Carl.
"OK. So what if you and Leni accidentally kissed? You didn't really mean to." said Carlota.
"Yeah. These things happen, mijo. Like when I accidentally kissed a girl who looked like Rosa." said Hector.
"I'm sorry. What was that, Hector?" said Rosa before picking up her chancla and threatening to hit him.
"Uh... The important thing is to forget about the past and try to mend this crazy sitch." Hector said to Bobby.
"What's the point? Lori doesn't love me anymore. I'm never gonna be happy again." said Bobby.
"OK, then. Good luck being a sad sack for the rest of your life, without a wife." said Carl before being thumped again by Ronnie Anne.
"Ow! How strong are you, girl?" said Carl.
Meanwhile, at the Loud's cabin, Lori is in her bedroom ripping pictures of her and Bobby to shreds in a fit of emotional rage.
All the other Louds check in on her.
"Lori? Lori Loo? Are you alright?" asked a concerned Lynn Sr.
"GET OUT!" shouted Lori.
She shouted at Lynn Sr. so loud, he gets blasted out.
"Yeah, she's definitely not fine." said Lynn Sr.
Rita says to Lori "Honey, I know things are difficult for you, but that's no reason to take it out on Leni."
"Leni who?" said Lori.
"Your sister." said Lincoln.
"I have no second eldest sister. She can run off and elope with said ex for all I care. As far as I'm concerned, they're literally both dead to me." said an emotionally enraged Lori before slamming the door on her family.
"And I thought I had deep emotions." said Lucy.
"Wow. This is so serious, I can't even make a joke outta this." said Luan.
"But I can. Now that Bobby's her ex, his ex-tra dopey actions left him ex-traordinarily ex-tremely ex-communicated from her life. You could say it was ex-travagant. Hahahahahahahaha." said Mr Coconuts.
Everyone glares at Luan.
"What? It wasn't me." said Luan.
"Guys, maybe we should leave Lori alone 'til she cools off." said Lincoln.
"'til Lori cools off? What about my grotesque sunburn? It's not cooling off at all." said Lola.
"Let the aloe vera run its course, spoilt bratty sibling." said Lisa.
"You know, I can't help feeling awful about Leni too. Lori just said she was dead to her. That's so beyond heavy." said Lynn.
"Speaking of the subject of our second eldest sister, I couldn't help notice she's been absent from our cabin for quite some time." said Lisa.
"Hey, you're right. Where is Leni?" said Rita.
Meanwhile, Sergio is locked up in a cage held by Brock the tough steward.
"Squawk! Get me outta here. Please don't send me to a dark place." said Sergio.
"Should've thought of that before you stowed away on here, bird. Now you're gonna pay." said Brock.
Brock opens the door to a utility room and throws Sergio inside.
"Just you wait 'til we hit land. I got tons of punishment ideas for you. Hehehehehehe." said Brock before shutting the door.
"Oh, triple summer bummer." said Sergio.
Then, he hears crying from behind.
"What the? Who's there?" asked Sergio.
It was Leni, who was looking at pics of her and Lori on her phone.
"Hey. What are you doing here, girl?" asked Sergio.
Leni sees Sergio and says "Oh, hey. I'm down here cos I can't stand to face my sister again after what I did and what she said to me. She said I was dead to her."
Leni starts crying.
"Ah, big whoop. It's not like that's as heart-wrenching as me and the buffet. All those delicious hot wings, that spicy enchilada, those crispy crackers. Oh, who am I kidding? This is definitely heart-wrenching for me too." said Sergio before bursting into tears.
"Lori was right. I am a stupid, idiotic girl. I ruined the biggest night of her life all because I got the taste of her now ex-boyfriend on my mouth." said a tearful Leni.
"Lucky." said a tearful Sergio.
"You know, bird. I don't think I can live like this any longer." said Leni.
"What do you mean? Are you saying... No. You couldn't." said an assuming Sergio.
"I can't live in this filthy room. It's too dark for me and it's making me even sadder." said Leni.
"Oh, that's what you meant. Yeah, me too. Say, whaddya say we vamos outta here before I get caught?" said Sergio.
"OK. Anything to clear my mind from this disaster I caused." said Leni as she lifts up the cage Sergio is in and they both leave the utility room.
Leni continues to walk along the deck.
Meanwhile, the little squid is being chased by stewards.
"Hey. Stop that squid. Put it back in the aquarium." said one of the stewards.
The squid leaves a trail of ink on the floor.
As it does, Leni doesn't realize she's headed for it.
"You know something else, bird. I just got the feeling I don't wanna be needed here anymore. Maybe I should just run away so that I don't ruin other people's lives again." said Leni.
She then slips on the ink, causing her to lose control of balance and speed.
She bumps into a button that releases a lifeboat, which she and Sergio fall into.
The lifeboat drops 1,500 feet into the ocean as the SS Aqua Voyager continues to move.
Leni and Sergio are left stranded on a lifeboat in the middle of the ocean.
"Ah! I take it back! This was not what I meant!" said a panicking Leni.
"What the heck, girl?! You got us stranded!" Sergio shouted to Leni.
"I'm sorry, bird. Oh, why must I still be an idiot?" said Leni.
"Squawk! And now we're gonna starve. Thanks a lot, ditzy girl." said Sergio.
"Well, at least there's no danger in the ocean. That's good, right?" said Leni.
Wrong, because from a few miles behind Leni and Sergio, a band of steel-toothed sharks see both of them.
They smile, signaling their intent to devour them.
