Summary
The intention of keeping Timmy in a good light was rearing in Jimmy’s head, he knew Timmy didn’t mean any harm. But, in his heart, he felt betrayed.
It was a classic fight between the two boys, banter, even. The difference about the severity of the situation was that the topic wasn’t about team issues, weapons, and how plans turned out.
This was about their relationship. And how much effort they both put into it.
A conversation that would go well if these boys weren’t so stubborn.
-
Or a little bump in Timmy and Jimmy's relationship that makes them really think. For better or for worse.

Summary
“Yes, Cindy?” James asked with a smirk, not looking away from his reflection.
Her face seared with anger. “I thought I told you not to call me that, Neutron,” Cynthia spat with a glare, crossing her arms. Her forest green sequin-adorned dress glimmered in the low light of the break room.
“Come to tell me that you wish I had an aneurysm again?” he chuckled, combing his hair rhythmically and repetitively to get the chocolate brown swirl just right. “Hate to break it to ya, but I think I've heard that line before.”
*•°•*
Set in the mid 1960s, James Neutron is a lonely lounge singer with a dream to be the next Einstein and the ability to store his entire life savings in his front pocket. Oftentimes, he's competing with the other vocalists like Liberty Folfax and Cynthia Vortex for the spotlight. They have the voices of songbirds. Him? He's no Bobby Darin or Frank Sinatra, but it puts bread on the table.

Summary
Skyler wouldn’t say she’s the most irritable person. Sure, she could get frustrated, but she’d still be able to talk it out if the other party stayed civil. She may not start fights, but she sure as hell knows how to finish them. Except when it comes to literally anybody she cares about. The second anyone she’s close to, be it a sibling or a close friend (or Alfred ) is on the line is the moment where she loses her shit. And yes, she does in fact start some fights. These are just 5 instances where it’s happened. (plus a bonus time of many where all of the CHAOS operatives do the same for her)

Summary
After what happened last time things seem to have gone back to normal though none of them would think of the loophole that Marcel had found. Meanwhile it is time for people from the modern stone age family show to have their fun with the club stud.
From here on I'm taking a break from this series since I plan to do original series only once The Simpsons ends as well but I will pick this up once one of them ends.
