Perhaps the fanfiction involves Sid being a new neighbor in the Loud House neighborhood. She meets Lincoln, and they start a club together. They face challenges like getting other kids to join and dealing with a bully who wants to shut down their club. This could lead to a lot of fun adventures and them learning about friendship along the way.
There might be a new character introduced in the fanfiction as the antagonist. A kid from school who is jealous of Lincoln and Sid's new friendship. This character could spread rumors about them or try to break them apart by causing misunderstandings between them.
In the fanfiction, Lincoln and Sid could get into some comical situations. For example, they could accidentally cause chaos while trying to cook a meal for the Loud family. Or perhaps they team up to prank Lincoln's sisters, but the prank backfires in a hilarious way. Their meeting could also lead to a deeper understanding between them, where they learn about each other's family dynamics and how different yet similar they are.
One way could be that Sid hears about Lincoln through mutual friends in the Loud House universe. Maybe they both like the same hobby, like collecting comic books. So, Sid could go to a comic book convention where Lincoln is also present, and that's how they meet.
They could talk about their families. Lincoln has a large and unique family, and Sid could share stories about her own family. For example, Lincoln might tell Sid about his sisters' crazy antics, and Sid could talk about her siblings if she has any.
Maybe Sid has a hidden talent that he reveals to Lincoln. For instance, he could be a master of martial arts or a brilliant inventor. But there's a catch - his talent is being hunted by some bad guys in the Loud House world. Lincoln then has to help Sid keep his talent a secret while also using it to save the day. This would add a lot of action and mystery to the fanfiction.
Personal insecurities could pose a challenge. Lincoln might be insecure about his ability to keep Nikki interested, especially considering his sometimes chaotic family life. Nikki might be insecure about fitting into Lincoln's world. These insecurities could cause misunderstandings and arguments between them as they try to figure out their relationship.
A possible plot could be that Sibella and Lincoln are arranged to be married. At first, they're hesitant, but as they spend time together, they fall in love. For instance, they might discover shared hobbies or interests that draw them closer.
