Jaune has an idea

"Can I see the gun?" Jaune asked.

"Sure," said Ruby.

She gave Jaune the gun, and he turned it on her, blasting Ruby with the Trigger setting.

"Please input trigger," Ruby droned.

"Ruby, I have a fun idea. Whenever I say 'Yang is so great' at whatever she is doing when acting out a trigger, you'll instantly mimic her wanting to outdo her."

"Trigger received," said Ruby.

Jaune then hit Ruby with the Reprogram setting.

"State desired programming."

"You believe I'll never use the gun on you, and won't question any time that's passed when you are in this trance."

"Programming received," said Ruby.

Jaune then waited for the sisters to wake up.
