The door swung open to reveal Yang Xiao-Long standing there in her yellow tank top and black shorts. Behind her was her sister, Ruby, sitting on the floor in a black t-shirt and shorts, holding a video game controller in her hands.

"Oh. Heya Vomit Boy. What's up?" Yang asked.

"Hi Jaune!" Ruby said with a smile. "What brings ya by?"

"What? I can't swing over to see my best friend?" he asked. Both Ruby and Yang's faces dropped to a sassy expression.

"Yeah right. Usually Ruby has to kick your door down to get you to come over. You want something." Yang smirked.

"...Okay fine. So I found a cool thing I wanted to show Ruby." he said as he pulled out the gun. Ruby darted over to him.

"Ooooooh! What's that?!" she asked, curiously.

Yang rolled her eyes playfully.

"Of course you found a toy gun." she chuckled "Fine. While you kids play with your dumb toy, I'm gonna hit the vending machines down the hall. Want anything, Rubes?"

"Soda please!" she chirped, as Yang stepped out.

"So what is it, Jaune?!" she asked.

Jaune had a couple ideas. First was using it on Ruby. The issue there was that he had to get any programming and playing done before Yang came back, but it was possible. The second idea... was convincing Ruby to use it on Yang with him. Then again, he hadn't thought too much about it. There could be other options.
