Cindy was in her Study Hall, reading a book called Carrie; she had everything done so she took the time to read her book.
"Cindy, how do you spell 'supernatural'?" Robin asked.
"S-U-P-E-R-N-A-T-U-R-A-L." Cindy spelled out as she read Carrie.
"Thanks." Robin smiled as she then wrote what Cindy spelled for her.
"No problem," Cindy replied. "Man, this book is very interesting, scary, but interesting. I feel bad for Carrie."
"You're reading Carrie?" Robin asked.
"Yeah," Cindy sighed. "I just wish there was something I could do, but she's just a book character."
The lights suddenly went out and everyone panicked.
"Hey, what happened?" Cindy wondered.
"The power went out!" Eddy told her. "And, Cindy, please, let go of my hand."
"But I'm not holding your hand, I'm sitting with Robin!" Cindy told him.
"Then who's holding my hand?" Eddy asked. "Oh, man, it better not be Lee Kanker!"
"Eddy, you're a firebender, surely you can make us some light?" Robin suggested.
"Oh, okay." Eddy said before snapping his fingers and fire came out of his hands, there was then something written in red which said 'I'M BACK'.
"Jinkies!" Cindy and Eddy gasped.
Cindy jumped in Eddy's arms Scooby-Doo style and the two of them ran out of the study hall and into the hallway. Cindy and Eddy ran off together as Robin slowly walked after them since they were in the hallways.
"Oh, my God, there's a ghost in this school!" Eddy yelped.
"What do you want me to do about it?!" Cindy replied. "I'm not The Ghostbusters!"
The two preteens heard footsteps coming down the hallway.
"Cindy, Eddy, is that you guys?" A female voice asked.
"The ghosts know our names!" Eddy panicked.
"Ugh..." The female voice groaned to their stupidity.
"You guys are idiots," Another voice said. "Do we look like ghosts?!"
"Stand back, ghosts!" Cindy warned. "I know Kung Fu, and I'm not afraid to use it!"
Mike soon put her hands on Eddy and Cindy's heads and made them look at her.
"Oh, it's only, Mike," Eddy said. "I knew it all along."
Mike rolled her eyes. "What's this about ghosts?" she then asked.
"There's a ghost in Study Hall." Cindy pointed out.
"Wait, I heard another voice too," Eddy said. "Who was that?"
"It was me," Sky said as she was right behind the young scammer which made him yelp. "I heard screaming, and I decided to check out what was going on."
"Sky, don't do that, I almost had a heart attack!" Eddy yelped.
"Sorry..." Sky replied. "Um, you saw a ghost, Cindy?"
"Well, I didn't see one, but the lights went out, and there was writing on the wall." Cindy explained.
"It was back at Study Hall, there was a sign in red which said 'I'm back'," Eddy added. "I bet it's just Duncan and Abby pranking us."
"If you think it was Duncan and Abby, then why did you get so scared?" Cindy deadpanned to Eddy.
"Why were you scared then, huh?" Eddy retorted.
"Touché, my firebender friend, touché." Cindy replied.
Mike and Sky came back into Study Hall to look at the wall only to see the writing there.
"There's the writing," Robin told the cousins. "We're not sure who could've written it... It might've been Duncan and Abby, but who can say?"
"Hmm..." Sky hummed in thought before touching the wall. "It's not Duncan and Abby Nelson, this is written in blood."
"Blood?!" Cindy asked.
"Yep, this is true blood..." Sky replied.
"Oh, my mother loves that show," Cindy smiled. "We just love Sookie."
"Not that true blood," Sky told her. "Blood from the writer..."
"Who would write in blood?" Mike wondered.
"The creepy librarian who hates noise in the library and gives you like a fine of $10,000 if your book is even one day late?" Eddy muttered.
"No, it's obvious that it's someone back from the dead." Sky replied.
"But who?" Mike wondered.
"It's probably Carrie who wants revenge." Eddy joked.
"Carrie?" Mike asked.
"I'm reading Carrie by Stephen King." Cindy showed her latest book.
"Hmm..." Mike hummed in thought before getting an idea. "Cindy, could I see that book?"
"Sure." Cindy replied as she handed the tomboy the book.
Mike took the book and then flipped through it as it showed the torture and bullying that poor Carrie White went through.
"I read that book in English Class," Sky memorized. "Poor Carrie, with all that stuff she's been through."
"I know, right?" Cindy frowned. "I just wish I could help her."
"And I thought that Samara had a hard life." Sky replied.
"You might be right about Carrie, Eddy." Mike stated.
"But Mike, I was joking!" Eddy replied.
"No time for jokes, this is serious." Mike said.
"But why here?" Cindy asked. "I mean, it's not like Carrie was a student here in Cartoon Network School or anything."
"Not necessarily, Cindy, but I think that maybe one of the adults probably went to school with Carrie." Mike theorized.
"But who?" Cindy shrugged.
"That's just what we have to find out," Mike said. "We'll have to solve a mystery of our own."
Cindy and Eddy just looked to each other.
