Lincoln's consciousness is dropped off in an unfamiliar region of his brain. Thankfully, there is a conveniently placed sign that tells him where he is.
"Prefrontal Cortex." The dream Lincoln reads off
He starts to walk toward the prefrontal cortex's fixtures. Proceeding forward, he sees a building off into the distance. He heads toward it. Eventually, he sees the building, which looks like a university. He notices a policeman and asks where he is and what this place is.
"This is Broad Man University, and we are in Lincoln Loud's Superior Frontal Gyrus. I'm Adolph. Though I look like a policeman, I'm actually just a neuron used to personify Lincoln's abstract concept of thought."
"Do you have 3 kids?"
"Yes. Hey, how did you know that?"
"I didn't. I got that from a SpongeBob episode."
"So, how does this place work?"
"It is an education building that houses all grades, from first grade all the way to college seniors. It's the only educational building in the entire brain, so everybody knows everybody here."
"Isn't it dangerous to have an intermingled student body?"
"That's why there are police inside the building, so that no funny business can happen."
A man comes out and speaks to Adolph, he looks like a renaissance man.
"Why aren't you at the 2nd floor, Adolph? You're supposed to be monitoring the middle schoolers."
"Right away, headmaster Corbin."
Adolph leaves. Headmaster Corbin then notices dream Lincoln.
"You. Are you a student?"
"No?"
"Then get off the campus grounds. I don't have time to deal with delinquents like you."
Dream Lincoln leaves.
"Warum muss ich mit all den Idioten umgehen?" Headmaster Corbin says under bated breath
A person that looks like Lisa leaves the university and goes over to talk with the headmaster.
"What's wrong?"
"Ah, my paragonal professor, what are you doing out here?"
"I'm on break. So, what happened?"
"Just a delinquent loitering around campus…I chased him off."
"…"
"You know, Clara, I used to be a POW of the Austro-Hungarian empire during the great war. They released me because I had a pneumonia infection and figured I would die soon anyway. They still tried to keep me a prisoner, saying that my brain was too important to science for them to just kill me."
Clara just looks at him.
"Huh…you know, headmaster, I worry about that boy."
"Why? He's just a random neuron floating around Lincoln's brain. It will generate more neurons. What makes him so special?"
"I don't know. But I have a feeling that something is about to go wrong…"
The next day…
Lincoln wakes up and gets ready to just lackadaisically lounge around and read comics in his undies until he receives word that his grades at school are on a gradual decline! If this continues, he'll flunk 5th grade! And no, this time is different because he wasn't ogling Ms. DiMartino like the rest of the 5th grade male student body. He needs to do something drastic...
He notices the trophy case. A standing reminder of how inferior he is compared to his sisters. He takes out the "Most Improved Brother" trophy and snaps it in twain! Shallow praise…everyone knows that that was a pity trophy. He heads outside and sees Lynn practicing one of her many sports.
"Hey Lynn, I have a proposition to make with you…"
"Are you sure, Lincoln?"
He nods.
A few days later and Lincoln's grades have improved. But there seems to be an unwarranted side effect, which Lisa takes notice of.
"Elder brother, I see that you're suffering from several hematomas. Being of average intelligence, you didn't rupture your own blood vessels; Therefore, I can conclude that someone is picking on you."
"Not this time."
"?"
"I assure you, I'm fine. Besides, my grades have never been better."
"Oh, forget about those! You're lucky that you haven't suffered an aneurism yet!"
Lynn comes out counting a small stack of bills.
"$5, $10, $15…"
"Lynn, someone is picking on Lincoln again!"
"Really?! I'll kill them for hurting you, Lincoln!"
"No one is picking on me! Besides, Lynn is a greater threat to me than Ronnie Anne ever was!"
"Lincoln?"
"See you later, Lis. Lynn, come on, there's a psychology test I have coming up and you're going to help me study for it."
Both of them leave.
"Lynn helping Lincoln with academia? Something is really wrong here…"
Lisa spies on their training.
"Ok, what Brodmann Areas are in the Superior Frontal Gyrus?"
"4, 6, and 8."
"Correct."
"What are the 3 regions of psychoanalysis?"
Hypoego, Ego and Hyperego."
"Incorrect."
Lynn punches Lincoln, while Lisa looks on with shock.
"It's id, ego and superego."
"Say, Lincoln, I really don't feel comfortable doing this anymore."
"Well, I'm paying you to help me ace my tests, so you don't have a choice."
"I can't do this anymore, I quit."
Lynn leaves.
Lisa enters Lincoln's room.
"So, you're paying Lynn to beat you up? Why would you do that?"
"2 words. "Operant conditioning.""
Lisa manages to put 2 and 2 together.
"Negative reinforcement? Why would you subject yourself to that?"
"My grades are tanking, that's why."
"Why didn't you just study?"
"I already did. It didn't make that much of a difference."
"What caused you to do this?"
"Because compared to you guys, I'm not smart. I just wanted to prove I'm on the same level as you guys."
"But you are."
Lincoln scoffs.
"No, I'm not, Lis. You're just saying that to make me feel better. We all know you think all your other siblings are ignoramuses."
"…"
"See?"
"But you don't have anything to prove to us, we like you just the way you are!"
"Stupid?"
"No, caring."
"…"
"Look, despite what I say, I really care about you."
"…"
"I know you don't believe me. But let me prove it to you."
"…"
"Remember when you stopped me from electrocuting Lily? I lost some important data, but because you did that, I don't experiment on our siblings anymore."
"You expect me to believe that?"
"No. I don't expect you to believe this either."
Lisa walks over to Lincoln, hugs him and says "I love you" to him.
"Platonically, of course."
Lisa did actually show genuine emotion to Lincoln. And Lincoln knows how hard it is for her to show genuine emotion…
"Alright, I'll stop."
"Thanks, Lincoln."
"No, thank you, Lis."
