Let's see what happens when Jaune goes with Sun to the White Fang rally instead of Blake.
Of all the things the White Fang enforce expected to happen when admitting people to the rally, this was not one of them.
"Sir, I don't think I can let him in," he said.
"Oh come on. Is there specifically a 'no pets allowed' rule?" Sun asked.
"People don't normally bring their pets to something like this."
"Well, I wouldn't be a responsible person if I left him home alone, now would I? Besides, my niece was so excited and supportive that she made him a mask. Look!" Sun held Jaune up, who had a paper White Fang mask colored with crayon.
"I… ok fine. But if you get in trouble, I never saw you."
"Deal. Thanks bro." They wade their way inside the warehouse. "Told you it would work. Your fur feeling ok?"
"Arf," Jaune nodded. His usually blonde fur was dyed black. It was a precaution in case someone recognized him as 'Pyrrha's dog'.
Plus it wouldn't be the first time his fur was dyed black.
"Girls, why did you dye Jaune's fur black?"
"It's not Jaune, it's a Grimm! I tamed him with my superpowers!"
Of course, the jig was blown when Jaune responded to his name being called.
"Man, there's a lot of people here," Sun noted. Jaune nodded in agreement. They weren't too concerned though. All they had to do was blend in and pay attention to how the meeting went and what information was given. Easy peasy.
And then Roman Torchwick hoped on the stage. He received negative fanfare but quickly charmed the crowd with few choice words. Sun grew a little concerned at this revelation, but he held his composure together for the sake of the mission.
Sun paid so much attention to Roman's speech that he failed to notice that his arms were empty until it was too late.
"Wait.. uh oh. Jaune?" he looked around. "Jaune?"
The mighty war beast maneuvered through the feet of the oblivious faunus as he made his way to his target. Soon he made it to the side up on the stage with his target in sight: Roman Torchwick, the man who hurt and almost killed Pyrrha.
The mighty war beast charged forward. Tonight, vengeance shall be had!
"Get the heck off me you mutt!" The entire assembly was put on hold as Roman shook his foot, but the dog kept a strong grip on his pants. Didn't the stupid thing know how expensive those were?
"Sorry!" A masked monkey faunus ran up on stage. "Sorry," he grabbed the dog and force it to let go. "Sorry," he apologized again, caring the growling dog back to his spot among the audience. His fake smile did little to hide his embarrassment. "Dude, what the heck?" he asked quietly.
"Grrr," Jaune regarded him softly.
"Bro, it's…" Sun sighed. "Just try and stay calm here, alright?" Jaune just seemed to grumble but listened. Sun thought that was that and went back to listening to Roman's speech, trying to take mental notes of what was said.
Unfortunately, he concentrated so hard he didn't notice Jaune jumped off after him again.
"Jaune stop! Get off the nice man!" Sun shouted as he ran back on stage to stop him from tearing Roman's pants. "Sorry." As Sun carried him away, Roman thought something sounded familiar about the name 'Jaune,' but he couldn't put his finger on it.
Sun held Jaune in a tighter grip, but he somehow managed to escape again.
"Jaune no, stop it!"
And again.
"Seriously, cut it out!"
And again.
"What did that man's pants ever do to you?!"
And again.
"He's a nice human Jaune! A nice human!" Sun managed to pry him loose, this time from Roman's cane, as he used it to defend himself. "Sorry," Sun never felt more embarrassed as all eyes were on him as they went back to their spot. "Jaune, seriously, cut it out," Sun pointed a finger in his face for emphasis.
"Don't be too harsh on him. He's a good boy," a masked faunus said next to them.
"And adorable," another masked faunus said as they scratched Jaune's ears. "Who wants to kill all the evil humans? You do, yes you do~." Jaune's angry glare was replaced with happy panting at the ear scratches. Sun looked around and saw that everyone around them was smiling at Jaune, some also even gave Jaune scratches or head pats.
For some reason, the thought of terrorists being nice to and loving dogs did not compute.
"Get that stupid mutt on a lease," Roman sneered.
"Racist!" Someone from the crowd called out.
"It's literally an animal that attacked me repeatedly!" Roman yelled back. "Wait a minute, I say to get an animal on a leash and your first thought is a faunus. I think you're the real racist here."
The faunus went to retort but paused, cupped their chin for several moments, and then left the assembly to rethink their life.
The assembly then got back on track, with Roman unveiling the star of the show: capture Atlas mechs with the White Fang insignia painted on them. Everyone cheered, Sun did as well but no one noticed the nervousness in his posture and voice. He had to find out if there was more and alert team RWBY. If the White Fang had more of these, then they could… he no longer felt Jaune in his arms anymore… again.
"Jaune no!" Sun yelled as he leaped onto the stage. "Get off the… nice… man?" Jaune was nowhere to be seen, much to the confusion of everyone. "Jaune? Where'd ya go?"
Everyone's eyes were drawn to the paladin as its cockpit hissed shut.
"Uh oh," Sun ran up to it. "Jaune, you in there buddy?" Jaune's muffled barks confirmed it. "Don't worry buddy, we'll get you out of there."
"Paladin online." The mech's computerized voice said as it whirred to life.
"Uh oh," Roman took a step back.
"IFF system offline Weapon safety disengaged."
"Jaune, we'll get you out of there, just stay still and stop pushing buttons!" Sun shouted.
It was good advice. However, since Jaune knew which buttons did what, he elected to ignore it.
"Target acquired." It raised its main gun. "Firing main cannon."
"Uh oh," Roman gulped.
"Uh oh," Sun said.
"Uh oh," several faunus in the rally said as they took steps back.
And then Roman exploded.
When the smoke cleared, only ash from the blast remained where Roman Torchwick once stood. There was also light coming through the ceiling in a newly made Roman Torchwick shaped hole. Seconds later, screaming could be heard and another Roman Torchwick shaped hole in the ceiling was made, followed by a Roman Torchwick shaped crater on the stage.
Not long after the meeting ended, Sun and a now human Jaune ducked back into a nearby alley.
"Dude, what the heck were you thinking?" Sun asked annoyed. "This was supposed to be a stealth mission and you did everything to bring attention to us."
"Sorry," Jaune apologized. "I… just lost it."
"What the heck did Roman do to you man?"
"He almost killed Pyrrha."
"... I… o-oh… damn. I'm sorry, I didn't know."
"It's alright man. She ended up recovering quickly. I just wanted a little bit of payback but… yeah I shouldn't have done that, sorry."
"It's alright. So, we're NOT going to tell Blake and the others you just became an unofficial symbol for the White Fang and are the reason for a 100% recruitment rate tonight, right?"
"Only if you help me wash this dye out of my hair."
"Deal."
As they left, a pair of pink and brown wide eyes watched them from the rooftop. Neo arrived later but wanted to see just who decided to hurt her man slave, only to find a monkey boy holding a dog that then turned into the puppy napper.
The boy was telling the truth about his semblance all along.
She… had some things to think about.
"Ah, Roman," Adam greeted, "I trust all went- what the hell happened to you?"
Roman brushed some soot off his hat. "Next time, make sure I don't miss the 'bring your kid to work day' memo."
Just to clarify, Neo was still the one who tried to kill Jaune/Pyrrha, but because they didn't see her there, Jaune blames Roman for it.
Thanks for reading, have a good day :)
