Have her bring her friends

"Just like Glynda," Duke said. "You'll be helping use recruit your friends."

"What?" Yang asked. "No way! I--"

"If you don't do it willingly we'll hypnotize you to do it anyways," Emerald reminded her.

Yang knew she couldn't argue, staring at her feet. "Fine. What do you want me to do?"

"Just try to get them alone as much as possible," said Duke. "And if I decide we need to keep one of them for ourselves, you'll make the others not worry."

"Keep them?" Yang's eyes widened.

"That won't come till much later," Duke assured her. "Once I'm confident we have all the women we want with a baseline programming."

Yang looked like she wanted to argue, eyes blazing.
