The Louds are at the Casagrandes' cabin where Lynn Sr. knocks on the door.
Maria opens the door.
"Hello, Maria. Listen, our daughter Leni hasn't returned to our cabin at all." said Lynn Sr.
"We looked all over for her. Do you know where she is?" Rita said to Maria.
"No. I don't, actually." said Maria.
Ronnie Anne pops up and says "Wait, Leni's missing?"
"Yeah. She's gone AWOL, dudette." said Luna.
"It has been an estimated 38.53 minutes without the presence of Leni in our selected ship cabin." said Lisa.
Carlos comes out and says "Leni never returned to you?"
"AY! One of yours has disappeared?!" exclaimed Rosa.
Frida arrives too and says "What? There's somebody missing? Oh, the humanity." before bursting into her trademark tears.
"That's why we've come to you. We need all of your help to find Leni." said Lincoln.
"Don't worry, lame-o. You can count on us." said Ronnie Anne.
"Right, then. Action stations, familia. There is a lost girl we have to find." said Rosa as the Casagrandes get ready to help the Louds.
Ronnie Anne races to Bobby in his bedroom where he is moping while holding the engagement ring for Lori.
Ronnie Anne opens the door and says "Bobby, come quick. One of the Louds has gone missing."
"How could that help to mend my broken heart? I have no faith anymore." said Bobby before crying.
"But Bobby, the Louds said Leni is missing. We think she's not on the boat anymore." said Ronnie Anne.
"Leni's missing?" said a surprised Bobby.
"Yeah. And the Louds need all the help they can get. Are you in?" said Ronnie Anne.
Bobby looks at the ring and says "OK. I'm in, sis."
The siblings race out of the bedroom.
Meanwhile, Lincoln races to the Loud cabin to look for Lori.
An emotionally distraught Lori watches TV about sister apologizing.
"I'm sorry I broke your bike, big sis." said sister 1.
"That's OK. I forgive you, baby sis." said sister 2.
The TV sisters hug it out.
Lori is disgusted by the scene and says "Literally never in real life."
She shuts off the TV and holds onto a pillow.
Lincoln storms in and says "Lori! We got a huge problem."
"You think you're the one with the problem? I just dumped my cheating ex for the cheating cheater pants that he literally is." Lori said with her fist clenched.
"But Lori. Leni has gone missing and we think she might've disappeared." said Lincoln.
"Leni who?" said a sassy Lori.
"Leni, our sister. A member of our family." said Lincoln.
Lori grabs Lincoln and says close to his face "Don't ever say that name in my presence again. I'm literally way better off without that brainless boyfriend thief."
"She was never going to steal Bobby away from you. That kiss was an accident." said Lincoln.
"Lincoln, we all know SHE always says the dopiest things and we don't believe her and sometimes we're right not to believe her. So, she can literally get lost for all eternity for all I care." said Lori.
Lincoln now grabs Lori and says "Lori, our own blood relative's life is possibly at risk, and all you can do is still consider her dead to you? What is the matter with you? Do you even care about family at all? A real sister would never consider another dead to her. A real sister always looks out for another, because once a sister, always a sister. Now, are you gonna march your butt out and help us find our beloved sister?"
Lori thinks about it and says "Leave me alone, Lincoln. I got better things to do."
"Fine! But if something terrible happened to Leni because you crushed her, it'll haunt you for life." said Lincoln before closing the door.
Lori feels frustrated after that talk, but maybe feeling a little guilt.
