"Hello, Evelyn Deavor, or should I say, Screenslaver."
Evelyn immediately woke up to find herself tied up to a mattress inside an ambulance with Stain looking up to her menacingly. She recognizes him as the Hero Killer.
"You!" she said with fear in recognition.
"So you know who I am," he commented casually. "You know it's wrong what you've been doing."
"What's going on?" she asked. "How did you know that I'm the Screenslaver?"
"Elastigirl has managed to track down the person who was thought to be the Screenslaver, but I'm not stupid," Stain started explaining while he uses a small knife to cut Evelyn's cheek for her blood. He licked it, causing her paralysis which is his Quirk. "I always knew that you hypnotized someone to avoid being implicated. After all, if you were the one to fight her when she fought the Screenslaver, you would have been beaten so easily."
"What do you want from me?" Evelyn demanded.
"To understand that what you've been doing is wrong," was the response. "This hatred you have against superheroes all because your parents were murdered by burglars, which that could have avoided if only your father had agreed to go hide in the panic room with your mother... it's quite petty, and I don't like it."
"Well, what about you?" she tried to contract him with a question. "Don't you hate superheroes as well?"
"You're right. I hate superheroes, but only those who were only out there for fame and money," Stain glared at her. "All I want is to create a just society of 'true' heroes by killing those heroes who I called to be 'fakes'."
"But look what you're doing to me!" Evelyn exclaimed while she can't find herself struggling due to the paralysis.
"I know," the Hero Killer continued with his explanation. "I also don't like villains who are out for unnecessary violence and bloodshed, and what you're doing makes another great example in my opinion."
Instead of using his sword to kill her, he has decided to use a defibrillator for the occasion.
"I am just trying to..." Evelyn tries to justify her actions.
"No!" Stain grabs her head to shut her up. "You were just trying to fulfill your selfish desire to keep the superheroes remain illegal," he lets go of her head afterwards as he uses the medical equipment against her. "That's all."
He puts it on her chest to shock her heart continuously. After a few seconds, her heart stopped and that she's now dead. With his work done, Stain immediately left the ambulance and flies away from town.
