After she finished her sandwich, Zelena got up and strolled towards the front office. She could hear the distant howling of an ambulance. The atmosphere of panic was evident inside the building, with everyone on the phone talking frantically. Through the windows, Zelena could see the students outside all running to the same place, to catch a glimpse at what had transpired only moments ago.
The time is perfect, Zelena thought, as she walked past the desk and straight into Mr. Walsh's office. He was on the phone as well, and from what Zelena heard, Walsh was speaking to Cecilia's parents.
"No... yes, an ambulance has been called... the sick bay... yes, I understand."
Eventually, the call came to an end, and Mr. Walsh's eyes fixated on Zelena, who sat down quietly. Zelena didn't know whether to expect fear or fury from the vice principal. A little of both, perhaps.
"You."
His eyes had become wide with horror, but his voice was a growl.
"Me?" Zelena smiled and raised an eyebrow.
"This was you!" Mr. Walsh rose from his seat, "I – how–"
"Are you accusing me of attacking Cecilia?" asked Zelena, feigning confusion, "I think you'll find many witnesses who'd gladly say otherwise."
Walsh walked over to the door, slammed it hard, before towering over Zelena.
"I don't know how," he snarled, "but this was you. You may find my actions disgusting, but you... not even blackmailing me will save you. I'm gonna tell–"
"What?" Zelena smiled, "You think anyone's going to believe I did this? Sit down, you fucking moron. You promised you'd elevate me to Gold classes when Cecilia was no longer a viable option."
"I'm calling the cops!" Mr. Walsh picked up his phone.
"Oh, I wouldn't bother," shrugged Zelena, checking her own phone, "They'll be here soon to take care of Ava. Although, I suspect they'll be here longer than anticipated. You see, those screenshots I used to blackmail you were sent to the police department three minutes ago."
Mr. Walsh's eyes bulged, and his grip on the phone tightened.
"So they'll also be paying you a visit, and I've made sure they find exactly what they're looking for," Zelena grinned, and looked over at Walsh's computer screen. Mr. Walsh turned to face it, just as the screen came alive with hundreds of explicit photos that forced even Zelena to look away.
"H-How?!" Walsh gasped.
"I know those photos aren't yours, but hey," Zelena stood up, "sometimes the truths that cut deepest need something a little extra."
She never listened to his begging, as she stepped out of his office and closed the door behind her.

By next morning, the news had spread around school. Ava had thrown some sort of chemical drain cleaner into Cecilia's eyes, and although Cecilia had been rushed into hospital, it was unlikely that Cecilia would ever see again. Ava was taken away by the police, who had to break down the locked door of Mr. Walsh's office. Inside, they discovered the vice principal hanging from a noose. No connection between the two events had been made, but many horrific photos of underage children were found on his computer. At an assembly, Mrs. Mills announced that the school year would be finishing three weeks early, due to these tragedies.

On her last day of Grade 10, Zelena was summoned to the front office. I've waited for this. When she got there, Zelena glanced at the empty office that had once been Mr. Walsh's. For once, she wasn't here to see him. Zelena was escorted into another office, where Principal Cora Mills sat in her chair.
"Hello Zelena," the principal greeted, gesturing to a chair.
"Good morning Mrs. Mills," Zelena sat in the chair, remaining calm.
"Regina has told me a lot about you," said Mrs. Mills. Has she indeed?
"She's one of my closest friends," smiled Zelena. The principal chuckled.
"Don't act for me," she replied dryly, "You've been coveting her spot in the Gold classes for years. You've set her up for sabotage in both her educational and personal lives. I must admit, I'm impressed... you remind me of myself at your age. You're smart, resourceful, and cunning. Your parents... must be proud."
"I only have a dad," Zelena murmured, "My mother died when I was born."
Mrs. Mills looked down and gave a small nod, before moving on,
"Cecilia Braeburn will no longer be attending Storybrooke High. Most of her eye tissue has corroded. It'll be over a year before she recovers from the trauma."
"How sad," said Zelena.
"It was an injustice, preventing you from entering Gold classes," said Mrs. Mills, "but you must understand that I'll do whatever it takes to help Regina succeed in life. Now that there is a vacant spot, I hope you will stop resenting Regina for the actions I've made."
Zelena looked up,
"Does this mean...?"
"Starting next year, you'll be in the Gold classes," Mrs. Mills nodded.
"Thank you," Zelena's smile was real, "I'll work hard, I promise."
"I expect nothing less," replied Mrs. Mills, "Go now. Enjoy your holidays."

"Zelena," said Eloise Gardener, "is more of a threat than I anticipated..."
The student council - aside from Regina - sat around the table of the conference room.
"...Regina suspects she was behind the leak that led to the attack on Cecilia, and we have reason to believe that she is behind Mr. Walsh's suicide as well. She craves power, and has the means to take it. She won't be satisfied with Gold classes. Before long, she'll turn her sights towards us."
"What do we do?" asked a blue-haired girl sitting across from Eloise.
"We find her weakness," replied Eloise, "and use it to destroy her."
