letting Penelope out

How stupid. Like it's not going to escalate. Gee, you want to leave her unsupervised and trust her not to mess with her mask or monitor. In a place filled with her old clients, since you used her black book, who will undoubtedly be happy to help her. Cheryl's arrogance will be her downfall, she's giving Penelope the tools to outsmart her and become a villain again for the second half of the season. That's Riverdale for ya.
