Lori, Lincoln, and Carol are still on the road to Great Lakes City. During the drive, Lori notices that one of the exit signs lead to her dream college that she'll soon be attending, Fairway University.
"Well... since we're already on the road, and it's only a couple miles away from Great Lakes, maybe we can pay a quick visit to my college. Just to see what the campus is like," Lori suggests.
"Sounds like a plan to me," Lincoln replies, as Carol also responds, "And me." With everyone in agreement, Lori turns onto the exit heading towards Fairway University. A little while after the threesome arrive, Coach Niblick greets, "Good afternoon. What brings you three here?"
"Hi, Coach N. Just wanted to take a look around campus while we were in the area," Lori explains. "Only a couple more months until I get to attend."
"Well, let me show you kids around, then," Coach Niblick insists, as he shows the trio around the university. They traverse the golf fields, the buildings dedicated to each class subject, and the student dorms.
After processing how eager Lori is to attend this college, Carol manages to slither away from the tour group while they're near the school's line of golf carts. She slinks into the women's restroom to give a call to Lorraine.
"Lorraine, I'm at Fairway University with Lori and Linky. And I've come up with another phase for my plan. In the meantime, you head over to the Loud house for Phase 2. Once you're done, come see me in Great Lakes City."
When the tour was over and the two Louds were about to return to the van, Lincoln notices, "Wait, where'd Carol go?" Luckily, Carol returns just as Lori and Lincoln were about to go searching for her. "Sorry, guys. Had to go use the bathroom during the tour."
Still being skeptical of Carol, Lori tells her, "Alright. Just don't wander off like that again."
With Carol back in their group, the three get into Vanzilla, as they resume their journey to Great Lakes City.
Meanwhile, back at the Loud house, the rest of the Loud Family were enjoying their Saturday afternoon. All of a sudden, some loud knocks at the door were heard.
"Coming!" Rita shouts. When she goes to answer it, she discovers that "Lori" came back home. But something about her was different.
Some differences Rita notes were that her tank top was in royal blue, had notable fissures at the end, and barely went past her navel. In addition, she had on a biker helmet with streaks of blue and yellow on the sides, a charcoal leather jacket, and raven finger-less gloves.
Rita also observes her jet black combat boots and sable denim jeans, which had severe tears on the sleeves. Plus, she had on heavier mascara, navy blue eyeliner, and the curved ends of her hair were now pointier. Something about how "Lori" appeared, made her look kinda bad.
"Lori, what are you doing home so early?" Rita asks. "I thought you were going to go visit Bobby in Great Lakes," Lynn Sr. chimes in. In response, "Lori" says, "It's none of your bullshit."
The sisters gasp when they heard "Lori" cuss at their very own parents. An appalled Rita then demands, "Also, where's Lincoln and Carol?"
"Lori" replies, "They're already at the city with Bobby and Ronnie Anne, and I gave Carol the keys to the van."
"Then how'd you get back here?" Lynn Sr. queries. "Lori" then reveals, "I have a ride of my own," as she points to the right.
Outside and on the driveway, there was a motorcycle parked. "I "borrowed" a motorcycle from some thug at a local bar," she claims, with finger quotations.
As the Loud parents were riled up at their eldest daughter for doing such nasty things, "Lori" says, "Out of my way," as she simply shoves them out of her way, making her way up the stairs and into her room.
The other Loud sisters were quite perturbed about their eldest sister's behavior.
"This is real messed up, dudettes." Luna says in confusion. "Why's our sis dissin' on Mom and Pops?"
"Why'd she leave Carol and Linky behind in the city?" Leni ponders.
"Why would she steal a biker's ride?" Lola says.
"I think the important question regarding of all this is, why's our eldest sister acting so different from what she once was?" Lisa states.
As the other Loud sisters were confused on "Lori"-'s strange behavior, Lucy starts to have a foreboding feeling about it.
"Guys... I'm starting to get a bad feeling that Lori isn't the sister we once knew." Lucy states. "She's going down a path, and it's not a very bright one."
Meanwhile, at Great Lakes City, Lori, Lincoln, and Carol had finally arrived at the big city where they would spend the weekend with Bobby and Ronnie Anne.
When they arrive at the Los Casagrandes building, they were greeted by The Casagrande Family themselves, as they all came together for a large group hug. Most notably, they were embracing Lincoln the most. They were really worried about him ever since Ronnie Anne filled them in on what happened a few months back.
Each Casagrande asked Lincoln if he was OK. However, Lincoln assures them, "Don't worry about it, guys. All of that's in the past. Besides, Carol turned over a new leaf since then."
"I beg to differ..." Lori mutters, just before Grandpa Hector enters. He informs her, "Bobby's just about done with his shift. You can go visit him in the bodega whenever you please." Thus, a gleeful Lori dashes into the bodega, with Carol following right behind, just so she could see where Bobby worked.
As for Lincoln, the Casagrandes bring him up to their apartment, where Rosa has prepared a tantalizing feast for him, just in case if he was still feeling a bit fastidious about the incident.
Down in the bodega, Bobby had finished his shift when he heard a certain someone call out his pet name. "Bobby Boo-Boo Bear!" It was none other than Lori, his beloved sweetheart. "Babe!" he calls out.
He and Lori embrace each other with open arms, as they snuggle together. Carol greets, "Hi, Bobby," only to be hissed off by Lori.
Bobby apologizes, "Sorry about Lori, Carol. Sometimes, she gets like that when any other girls try to approach me."
"How about you two meet up with Carlota upstairs?" he adds. Back on the Casagrande Floor, Lincoln has just finished off the last of the food on his plate, just when Ronnie Anne comes home. Spotting her companion at the table, Ronnie Anne gives Lincoln a great big hug, as she asks, "How's it going, Lame-o? Are ya feeling any better?"
Lincoln then brings her up to speed. "I'm feeling much better, Ronnie Anne. I've been having less nightmares about the incident recently, and that's mostly because I forgave Carol for that. Things are cool between her and most of my family now. Except for Lori." After hearing what just came out of Lincoln's mouth, Ronnie Anne was chagrined.
"Have you gone loco, Lincoln?! You've forgiven Carol after what she and her friends did to you?!" Ronnie Anne berates. Lincoln informs, "No, I'm not. Carol really has changed, Ronnie."
"Yeah, I'll believe it when I see it," Ronnie Anne responds. "Let's just keep a close eye on Carol, just to be safe."
As Lincoln and Ronnie Anne were hanging out, Lori and Carol were with Carlota in her room.
"Here ya go, Lori," Carlota says, as she lends her another set of big city clothes from the last time she came. "I got them just in case anything happened to the first set. After what happened the last time you were here in the city."
"Wow! That outfit's really cute! What store did you get it from?" Carol asks.
"I got it and all my other clothes from The Swift Thrift," Carlota answers. "A girl's always prepared in case of any accidents."
"Don't you get any ideas, Pingrey," Lori threatens to Carol. "You are not stealing my city look."
Little did Lori know, Carol had plenty in store, with one that will soon be part of her collection.
Since "Lori" left Vanzilla back in Great Lakes, Lynn Sr. and Rita had to rent a van for temporary use until Lincoln and Carol came back. The other Loud sisters also get in the van so their oldest sibling can have her space, but mostly so they wouldn't incite any of her potential ire. While the Loud family was away to enjoy the outdoors, "Lori" knew, "It's go-time."
Lorraine went into each room, desecrating all the Loud sisters' personal belongings, especially the gifts that Carol got some of them. She rips the head off of Lily's new doll, breaks Lisa's tablet in half with an axe, cuts Lola's new dress into chains of paper dolls, and tears out the pages of Luan's joke book.
She also smashes up Lucy's Vampire Statue with a sledgehammer, breaks all of Lynn Jr.'s sport equipment and trophies, smashes all of Luna's instruments, and ruins all of Leni's fashion magazines and dresses.
When she was through with those rooms, the only room she didn't go into was Lincoln's, because Carol told her she had something very special lined up for him and that it wasn't necessary to invade his room.
Once Lorraine was done ruining all the stuff upstairs, she barges into the Loud parents' bedroom. There, she breaks Lynn Sr.'s prized cowbell, in addition to ripping out, scribbling over, and crumpling every page in the novel Rita's been writing.
"There." Lorraine said. "That should be enough. Time to head over to the city."
When she was all finished, Lorraine got onto her motorcycle and drives off to Great Lakes City.
Later that day, when the Loud family came back, the sisters head into their rooms to discover that all their prized possessions have been defiled! Rita and Lynn Sr. also discover that their stuff had been violated too. The only question on everyone's minds was, "Who did this?"
"Fortunately, I've come prepared for such occasions as this. Everyone, into my room," Lisa states. Although her lie detecting goggles were destroyed, her cameras were still intact, and she's been using them mostly for security purposes. She presents the family with the monitors of each room, showing them what happened through prerecorded footage.
"I can rewind these screens to the part where we left the house in the first place." Lisa said, rewinding the videos. "We'll soon find out what happened while we were away."
But when Lisa managed to the part when the family left the house, what they saw next brought shock and confusion to them, for they saw "Lori" ruining their rooms and breaking their stuff. The family thought Lori has gone rogue. What they didn't know was that the "Lori" they saw, wasn't the real Lori.
"Oh my gosh!" Leni says. "Is that... Lori?!"
"Bogus! She busted up the place!" Luna states.
"But where is she now?" Lucy wonders. "Probably off on her ride." Lynn Jr. figured.
"How could she do all of this?" Lana says. "I thought she was better than that."
"Whatever the case may be, girls, your father and I are going to have a little talk with her." Rita says in a stern voice. "IF she ever comes back home."
Later that night, in Great Lakes, Lincoln was bunking with Ronnie Anne in her room while Lori was sleeping with Bobby. But, one person in the apartment wasn't asleep.
Carol waited patiently for everyone to go to sleep, as she then dons a women's fedora, a purple dress, a dark purple trench-coat, pantyhose, and heels. Grabbing an umbrella to complete the look, Carol sneaks out of the Casagrandes' abode and makes a nightly stroll towards another part of the city.
And in that region of town, was an abandoned apartment building. There in said building resided a syndicate of teenage female bikers that recently escaped from juvenile hall. And with those bikers were some of Carol's acquaintances that turned to a life of crime: Belle, Whitney, Fiona, and Becky.
They were all waiting for someone special. Some of them were growing impatient for her arrival.
"Ugh! What's taking her so long?!" Fiona groans, with Whitney and Belle in agreement. "It's not like Carol to keep us waiting like this," Becky says. "I say we go out and get back at Lori right now!" Whitney suggests.
Before they could do anything, Stiletto, the all-female biker gang's leader and and an associate of Belle's, tells them, "Not yet, girls. We're still waiting for Carol to get here."
Soon enough, Carol had arrived. Everyone greets her and asks if she had anything important for them to do. Carol then introduces, "Girls, say hello to our new guest," as Lorraine walks inside the headquarters.
At first, Carol's friends confused Lorraine for the real Lori, believing that their ally ratted them out to the enemy. Carol explains, "Guys, this isn't Lori. This is Lorraine. She's a stunt double I hired to help us with our plan to get back at Lori." Now, everything was made crystal clear to Carol's associates.
QT asks, "How exactly is she going help us get back at Loud?"
Carol explains, "Well, old Lorraine here helped out with trashing the Loud house during Phase 2. Now that she's here with us, "
She then turns her attention to Stiletto. "I'll need you and your gang to help out for Phase 3, Stiletto," she asserts. Taking interest, Stiletto asks, "What do you need help with, Pingrey?"
"Earlier today, I learned that Lori's gonna be attending a college called Fairway University soon. From what I saw, it's some stuffy old golf college that doesn't know how to party..."
An intrigued Stiletto inquires, "Oh, I take it that you want me and my gang to throw this college the gnarliest, awesomest, raddest, most ravin' party they'll never forget?" Carol nods and also tells her, "Better invite 'Lori' too... She'd hate to miss it," obviously referring to Lorraine.
"Like, a college party?" Lorraine perks up. "Yeah." Carol replied. "Stiletto, Lorraine, here's what I have in mind for Phase 3..."
Stiletto and Lorraine group huddles with Carol as she whispers her plan for Phase 3. Whatever she was planning was for a party at Fairway University, it wasn't going to be very peaceful.
