The culprit

"Lily, why?"

When the school bell rang, Lily, Penny, and Ginnie walked their way out of the building using the longer route. This time, they were taking this path not because of Penny, but because of Lily. 

Lily pursed her quivering lips as she looked at Ginnie. "I was a little angry and told myself I'd just tell him things nicely. But then, my mouth wouldn't stop!" She then clung to the little Penny for help. "Penny, am I dead?"

Penny's face contorted as she thought about what Lily had told them. They wanted to ask her when she got back from the restroom, but their teacher arrived. During their self-study class, Lily was so distraught they didn't get an answer from her. 

Lily only confessed when she asked them to take the other route. 

"You'll be fine, I guess?" Penny laughed awkwardly. 

"You guess? You're not sure?" Lily dramatically wept, her anxiety skyrocketing at the thought of Ray's wrath.
