Ethan knew he couldn't do what his family asked when it came to hurting you, but after hours of Quinn telling Ethan that you'd never want him, and that you would never see him as anything more than a pathetic loser, he'd channeled enough rage towards you to hopefully do the job he was asked to do.
When he popped out of Quinn's closet that night and killed her flavor of the week, the adrenaline was already pumping through his veins. When he went out to the main area of the apartment, he searched for you. He thought back to the text you sent him about being bummed that he had econ and couldn't join you and the rest of the friend group, so he knew this was where you were supposed to be. He didn't let you not being there throw everything off, it just meant Anika had to die before it was originally planned.
He met with his dad before he had to show up at the crime scene and play the roll of the grieving father to explain how everything actually played out.
"She wasn't there?!" Wayne yelled, as Ethan nodded, his breathing still heavy from all the running to get away from the apartment before anyone had a chance to see him. "Fuck, I thought you had this all planned out!"
"I'm sorry," Ethan said, "She was supposed to be there. I guess she changed her mind."
"You're going to finish the job though, right?" Wayne asked, knowing how much convincing it took to get Ethan to want to kill you in the first place.
"Yeah, I'll take care of it. I know tomorrow's supposed to be the end of all this, but I have her schedule memorized. I'll just break into her apartment before she get's home from class, kill her, and I'll meet you at the theater," he said, as Wayne nodded in approval.
"I knew you wouldn't let me down."
The next day, you went to class. You'd heard about another attack but had no idea it was Anika and Quinn. With you backing out of coming over to Tara and Sam's last minute before the attacks happened, your friends couldn't help but wonder if you could've been the one that caused her death. You were the last person they'd suspect, but they thought it was a little strange.
Finally, Tara called you when you were walking back home after your morning classes.
"Hey, sorry I didn't come over last night. I was so tired," you said, as soon as you answered the phone.
"It's a good thing you didn't," Tara said. You immediately heard the sadness in her voice.
"Wait, what happened?" you asked, before you heard Mindy yelling at Tara for calling you in the background. "Tara, what's going on?"
"The killer came to the apartment last night...Quinn and Anika are dead," she said, as you were walking through your front door.
"Oh my god," you said, bracing yourself against the doorway as you took in the news she just told you. "Is Mindy okay?" you asked as you started to get emotional. You weren't the closest to Anika yet, but you were getting there. You loved her sweet yet sarcastic personality, and you'd recently started to get to know her better from the study sessions with her and Ethan.
"No, not really," Tara sighed, "Were you really home last night? I hate to ask you because I don't think you'd do anything like this...but you saying you weren't coming over last minute was a little suspicious."
You were taken aback by her accusations, and were about to respond, when you heard the beeping that someone else was calling you. You felt annoyed as you saw the unknown number, quickly declining it before you responded to Tara.
"Tara, I promise you I was at home. I was so tired after class yesterday," you got out, before you started to get another unknown number call, "Fuck, someone keeps calling me. I'll text you in a little bit. We'll figure out who's doing this."
