At the comic book store, Lisa entered the establishment while wearing a trench coat covering her body and a fedora hat. "Excellent, this disguise will make sure nobody manages to figure out who I really am!" Lisa proudly thought. "Now to go buy the issue."

The small kid went to the comic shelves and remembered what issue she read, "Okay, the issue I read was apparently Issue 17, so I need to find the 18."

So she started to look. She managed to find the 16th issue, and the 14th, 13th, even the 19th and 20th issue, but the 18th issue was nowhere to be seen. "Where is that stupid Japanese comic book?!" Lisa spat before calming down. "Okay Lisa, calm down, you're not getting anywhere by getting angry."

Lisa went to the counter and her small size quickly caught the guy's attention. "Excuse me sir, but I'm looking for Ace Savvy issue number 18th, and it seems to be lacking in your shelves," Lisa explained to the guy behind the counter. "Do you know

"Issue 18th? Well yeah, a kid named Lincoln Loud bought the last copy we had of that issue," the guy answered. "We'll restock tomorrow, though, so you may-" but Lisa had already left.

Back at Lisa and Lily's Bedroom...

"I don't know how he did it, Lily, I don't know when he did it, but what's important is that he did it!" Lisa proclaimed, walking back and forth. "Lincoln bought the issue before I could! And now, to figure out what was the result of the secret weapon clash, I'll have to try and take the book from Lincoln's bedroom."

The baby just laughed. "Quit laughing at my misery, Lily!" Lisa hissed, right before remembering something. "Speaking of which, while I was gone, did anybody outside of Leni come here and see the comic book? Did you spill the beans?"

Lisa checked Lily's diaper, which had been recently replaced. "Well, you did something with the beans if you needed Leni to give you a diaper change," closer inspection revealed the diaper was not upside down, or backwards, or any sort of mistake. "More surprisingly, though, is that she did it right for once."

Lily then hit Lisa's face with her hand. "You're right, I need to focus on the mission," the duo separated and Lisa walked to a blackboard, one filled with a bunch of doodles forming a plan. "And this is what I'll do: I'll go into Linc's bedroom while he's out, then I'll look everywhere for the issue, then I quickly read it and return it to its spot before coming back here!"

The baby blinked silently. "You know, sometimes I wonder if you even know what I'm telling you, and if I'm a genius or an idiot for thinking you really do understand."

So Lisa took a peek out of her room's door, and when she saw Lincoln come out of his room and go downstairs, she quickly went inside and started to look around for the 18th issue. She eventually found it in his desk, and she soon took it and opened it. "Okay, let's see what we have here!" Lisa chirped as she got on Linc's bed.

"Last time, on Ace Savvy," Lisa said, acting as the narrator. "The magnificent hero known as Ace Savvy, and Professor Doctorade were about to unleash their secret weapons! And now, we continue-"

"Lisa?"

Upon hearing Linc's voice, Lisa turned to see Linc, holding a glass of water and standing next to her. "Why are you reading my comic book?"

"Uh... um..." Lisa stammered before pointing outside. "Look, Lucy's over there!"

"Actually, I'm here," Lucy said while being on the opposite way Lisa was pointing at.

Lisa and Linc freaked out, and the little genius took the chance to flee, with Lincoln giving chase. "Sigh, once again, I'm ignored," Lucy remarked.

Linc chased Lisa as the smart brunette hid the comic book as well as she could: they ran through the living room, the basement, the attic, and up until Linc lost Lisa in the middle of the hallway. The girl went to the kitchen, where she caught her breath while Leni prepared a sandwich. "Oh hi Lisa, what's up?" she greeted.

"You saw nothing!" Lisa exclaimed before fleeing once more.

Leni shrugged and bid farewell. "Okay, bye nothing!"

And then Lincoln arrived. "Leni, did you see where Lisa went?"

"I don't think so, but I did see where a nothing went, and it went over there," Leni explained before pointing at Lisa's location.

Linc nodded, resumed the chase and eventually the duo stopped at the garage. "Okay Lisa, you got nowhere else to run!" Linc stated as he approached the girl. "Now tell me, what were you doing in my room?"

Seeing she had no escape, Lisa caved in and showed the book to Lincoln. "I went to your room to read this," she answered, looking at the ground.

"My 18th issue of Ace Savvy?" Linc took the issue and eyed it. "Why would you want to read this?"

"Long story short: I read the 17th issue to see if it was quality material, but I ended up liking it too much. And it ended on a cliffhanger, so I had to get my hands on the 18th issue to complete the picture!" Lisa explained.

"Well, how about we read it together?" Linc suggested.

Lisa was surprised at his response. "Really? You're not angry?"

"Why? It's good to have a fellow Ace Savvy fan in the house," Linc replied before offering his hand to Lisa. "So come on up, let's find out the aftermath of the secret weapon brawl."

Lisa smiled, eagerly took the hand and the duo ran to the living room. A couple minutes later, the duo were laughing and reading the issue together. "Man, that was a brawl and a half!" Linc exclaimed.

"I know right?" Lisa replied with a chuckle. "The part where the shark came out and shot lasers out of its eyes, while breaking a bunch of scientific laws known to mankind, was incredible!"

"I liked the part with the rabbit," Linc added, rolling his eyes.

"Oh right, that part was pure genius," Lisa looked at the ground before asking, "Lincoln, do you mind keeping this a secret? I am the smartest of us all, after all, and having cultivated such a know-it-all scientific attitude, I think the girls would never stop bothering me if they found out I read Ace Savvy with you.

"Sure, this is between us," Linc replied.

The duo shared smiles before Lisa hugged Lincoln, with the guy looking surprised for a moment before gently returning the hug.
