Who's Yang?

"Huh?" Ruby asked confusedly. "What's a Yang?"

Jaune laughed inwardly. "That's, um, not important. I'm just here to pick up my mannequin."

He motioned to Yang. Ruby nodded.

"Take it. I don't know why you insist on leaving it here anyways."

Jaune was amazed that Ruby now viewed her sister as just a mannequin, but to her, Yang didn't exist.

"Who's the fourth bed for?" Jaune asked, pointing to Yang's bed.

"Guests, obviously," Ruby said in an indignant voice. "Now get out."

Now that Jaune new that the collars worked, he could use one on Ruby now...
