Lincoln and his family was watching Monster Inc. During the middle of the movie, Lincoln pause the movie, much to his sisters annoyance.
"Lisa?" Lincoln asked his 4 year old sister.
"Yes male sibling?" Lisa said.
"I have a question that science still can't answer!" Lincoln said.
"Pfft, I bet I can answer that question for you!" Lisa said.
"Okay ready?"
"Affirmative!"
"Does Mike Wazowski blink or wink?" Lincoln asked.
That question confused Lisa.
"Dang it, I knew I should've watch Rick and Morty, the smartest show in the world, for this question!" Lisa said in her mind.
"Oh, I know the answer!"
Everyone turned to Leni.
"Pfft, I doubt you know the answer!" Lincoln said.
"Quiet Linky, at least I didn't fail lunch 9 times in a row!" Leni scolded.
Lincoln frowned. Leni felt bad.
"Sorry for scolding you Linky!" Leni apologized.
"It's okay!" Lincoln replied with a smile.
"Anyways, Mike Wazowski actually...!"
10 minutes later
"And there's your answer!" Leni finished.
The sibling's, even Lincoln and Lisa, jaws were wide since Leni manage to answer that question even if she's dumb.
"Oh, and I didn't see that one episode from Rick and Morty so I'm not dumb!" Leni informed her siblings.
This made Leni's siblings jaws going more wide.
Leni then revealed that she actually been smart her entire life and she has been keeping this secret from her siblings her whole life. Leni also said that if Lisa couldn't answer a question, then she would reveal her secret.
Turns out that all her failed test and project were actually fake. Leni then help her siblings with school and they all get A.
The Parents then came home and told their kids that they were all adopted and the only biological children of the Loud Family was Lincoln, Leni, and Luna.
The sisters, except Leni and Luna, didn't complain about being adopted.
Everything was normal and Lincoln moved into Leni's room and Lori's room was now a closet. Now Lincoln has a roommate and will not be alone.
The End.
