Author's Name: Thanks to Thegonk on Deviantart for making a massive list of errors I've made during earlier chapters so I could go back and fix them.
After arriving at Skinner's place with their damaged cars. Skinner made sure Chalmers wasn't looking for taking the food and drinks items inside. He quickly went into the kitchen with them while Chalmers sat down next to the dining table.
After a few minutes of pretending to prepare the 'Steamed Hams', he came out with them on a plate and two bottles of champagne in between his arms. "Well Chalmers, it's the moment you've been waiting for, the one and the only, 'Steamed Hams'!" Skinner said excitedly.
As Chalmers took a bite out of one of them, he said: "I still don't understand why these taste like the burgers you get at Krusty Burger…". "Again, it's an old family recipe. I guess the similar taste is a coincidence." Skinner replied nervously.
"Anyway, I wanted to talk about 'The Springfield Elementary Disappearances' with you." Chalmers told him. Skinner felt butterflies running through his stomach upon hearing that and after a few seconds, he said: "Oh that, it's been mentioned throughout the news in Springfield."
"Yeah, I've been reviewing the security footage and I've noticed that whenever that one minute, the student is clearly visible and then the next, they're gone!" Chalmers said to Skinner, who was getting uneasy about the subject.
"Well, I clearly can't understand why they would vanish suddenly without ever been seen again…" Skinner said, really starting to get worried that Chalmers was on his case. He then told him "Look, mother needs to be picked up from her… Uh, parenting camp." He said. Of course, this wasn't true as he murdered his mother a while back and was just using this as an excuse to get Superintendent Chalmers out of his house.
"Well, I guess I'll be heading off to…" The superintendent said. The both of when went to their damaged cars and took off. After making sure Gary wasn't taking the same route as him, he turned onto the main road and headed to the school so he could do his usual tape tampering.
The next day, Skinner realized something about the victims he'd been choosing. All but one of them were boys. He figured that it was now time to start picking more girls as his victims. But there was still another problem, which one would he pick? Sure, there were loads of them, but he just couldn't pick of one of them.
Then, he realized that his answer would come in pairs, literally. "Maybe I could target Sherri and Terri as my next victims. After all, they're starting to creep me out with their secret twin speak and shit like that…" He told himself.
After that was decided on, he went on hunting for them. It wouldn't take long before he overheard them speaking in their secret twin language in the girl's bathroom. "Perfect…" He said quietly. Both girls left the bathroom and began chatting and giggling away.
"So Terri, do you have any idea what happened to Bart?" Sherri asked her sister, who was just as mystified by 'The Springfield Elementary Disappearances'. "No sis, Bart hasn't been seen for several weeks now!" She replied. Just then, Skinner grabbed the duo by their long purple hair.
"Whah?" They said, before hearing a familiar voice behind them. "Hello, Sherri and Terri, whichever of you is which!" The voice went. They both turned around to find it was Skinner holding them by their hair. "Skinner, what are you doing?" Both of them said. "I have a special surprise for the both of you!" He said, with an evil look on his face. The two twins both had their legs dangling in the air as Skinner took them to his death chambers.
Upon arriving there, Skinner was still gripping to them tightly by the hair and went into a room called "Acid". Both girls looked at each other nervously as the Principal took them into the room. There were two shower cubicles inside, each looking to fit one twin inside it. Skinner threw the two into the separate cubicles and locked them in there.
"Let us out!" The two repeated over and over, banging the doors at the same time. Of course, Skinner just ignored them and fired on the acid. Sherri felt the top of her head beginning to burn up as the acid melted through her hair bow. "Ahhhhhh!" She screamed at the feeling of the burning acid. "Hang on, why hasn't any fallen on me?" Terri asked nervously.
Skinner had a reason why only Sherri was currently receiving acid water, and not her younger sister Terri. Inside Sherri's shower, there was a button on the wall which when pressed, would stop the acid water pouring onto her. There was a catch though, as pressing the button would redirect the acid to the other cubicle which was holding Terri. It was a true test of Sisterhood indeed.
"Hey Sherri, if you don't want the acid to harm you any further, press that button on the wall." Skinner whispered to her. By this point, her feet and hair had partially melted away, so she was bound to press the button. However, Skinner didn't tell her about the catch to the button and she pressed it unaware of the consequences.
Sherri then heard a shrill scream come from what could only be her sister in the other shower. She then realized that pressing the button would direct the acid to her sister, leaving her with the toughest choice of her 10-year life.
"Skinner, just take me and let my sister go!" Sherri said frantically, letting go of the button. Of course, Skinner turned down the offer as he wanted to kill both girls. Sherri's shoes and socks had melted completely at this point and the acid was melting through the rest of her clothing at this point. She was screaming loudly and the acid ate through her skin, while Terri was forced to listen to her sister's horrifying screams, despite her best efforts to block out the noise. She also had a problem of her own, the acid pool on the floor was eating through the soles of her shoes.
Sherri had decided that she had endured enough pain and pressed the button again, as much as she didn't want to. Terri screamed again as a fresh rain of acid poured onto her, eating away at her flesh on her hands and the bottom of her dress. Not wanting to listen to her sister's screams of horror, she released her finger from the button and had more acid pour down on her.
"I can't bear to see my sister dying!" Sherri said, conceding in defeat as the acid melted her flesh to the point that Skinner could see her guts and insides. Eventually, the acid melted her heart, leading to her death.
"Sherri!" Terri screamed when she noticed that her sister had died. "You sick bastard!" Terri said, banging the shower door loudly. Just then, she felt more acid water pouring down on her. "Ahhhhhhh!" She screamed. "You were saying?" Skinner said, with an evil grin on his face. In just thirty seconds, her face had melted off, exposing her brain to Skinner.
"Wow Terri, your brain is…" Skinner said before Terri interrupted with "Wait, how do you know I'm Terri?". Simple, I noticed that Sherri is always on the left, and you're on the right!" Skinner told her. Just like Sherri, she'd given up on getting out alive, especially after Skinner figured out which twin was which. It would only take a minute for her to succumb to the acid, just like the older twin did.
"I don't think I want to be touching either body after what I put them through…" Skinner said, putting the acid in both cubicles on full blast to melt away the rest of their remains. Once that was done, the rest of the school day went without incident and Skinner did his tape tampering once the school day was over.
