Why not add another?

Silvanus thought back to Pyrrha and Coco. It'd be a waste to have permanent women now and not take one of them, especially given the fact he could easily reprogram them.

"Glynda, you probably know your student roster more than anyone. Who do you think should join Yang here? Permanently, I mean."

"If I had to say...probably Coco," droned Glynda. "She often goes on long shopping trips alone, so it wouldn't be out of the ordinary for her to vanish. Just make sure to tell her to tell Velvet she's leaving, otherwise Velvet will worry if she leaves without a word."

"Ah, good idea," said Silvanus. "I knew it was a good idea to get you."

He took out his scroll to text Coco to come. "Yang, how do you feel about me adding Coco to our little...business?"

"I feel however I am programmed to feel," Yang droned.

After confirmation of Coco's impending arrival, Silvanus decided to kill the time.
