That individuals like you were something that Boomer would call rare. Considering how many villains he has to deal with in his life, you were probably one of the people he could not get along with for his life of him. Simply, I just can't keep your hands to yourself! Yeah, sure. He could an amazing Supervillain, terrorizing Townsville here and there with his brother, but wowe you take the cake. Not to mention you were from the infamous Citiesville. Of course, you were as bad as the people there. The place itself was overflowing with crime.
Mojo Jojo thought it'd be a great idea, socne you were just running amok. And because of your apparent intelligence and your criminal knowledge. Since they were the typical supervillain brothers and had enough space to fit a zoo, you would be staying here for your remaining time here, and oh, boy, were you a nuisance to all of them. Brick couldn't even stand you the first seconds you appeared on their doorstep, Boomer has tried his best, giving you the benefit of the doubt.
Yet, even he had his limits. He just didn't understand how your thought process worked to be so.. different. Did he forget too much that you were literally around his age? It's like you didn't know what privacy was with the number of times he had to chase you out of the comfort of his room. Not even Butch's or Brick's it had to be his you had to go and mess up.
Allegedly, you couldn't be trusted alone in the house or base, whatever they called it. And this time Boomer was the one assigned to watch you, and he was so far not enjoying it. You have been having a staring contest with him for the last few minutes, and he can't anymore! Everyone, when he told you to stop doing something, you didn't listen and gave him that nasty attitude he disliked so much and kept defying his every word. It was almost overwhelming to the point that he hadn't a clue what to do with you.
