Blake headed off, deciding to resume the chase alone for now. Jaune let her get to it, and then turned back to Penny, looking her over, before taking the Note out and writing, "Penny Polendina will answer any and all questions Jaune Arc has for her honestly, including sexual ones."

"What are you waiting?" Penny asked, tilting her head curiously.

"Oh, nothing important," he said. "So, what brings you to Vale?"

"Oh, I'm here from Atlas for the festival," Penny said happily that someone was showing interest in interacting with her.

"Nice..." he smiled. That meant she would be in town a while... "How often do you masturbate?" he asked.

"... what's masturbate?" Penny asked, tilting her head.

"...okay, we'll come back to that," he said, a bit weirded out. "Do you find me attractive?"

"I am unsure what you mean by... Attractive..." she said, putting a hand under her chin.

"Okay..." Weiss said in Jaune's ear. "She's... Odd. Asexual maybe?"

"Maybe," he muttered back, knowing he could use the Note to fix that.
