After Rapunzel, Astrid, and Kristoff got Jack and Flynn, they all went to Rupert's classroom.
They busted through the door, running straight to the room Rupert retreated to during the fairy 'attack'.
"He may be useless", Kristoff started, "but Rupert's going to get inside the Chamber!"
Astrid then said: "We can at least tell him what we know."
They came into the room.
"Professor!" Rapunzel yelled when they came inside. "We have something to tell you!"
They saw him throw two shirts into a suitcase, close it, and turn to them. They looked around quizzically…
Jack squinted his eyes at Rupert. "Are you going somewhere?" He asked in a disgusted manner.
Rupert stammered for a second. "Yes. It's quite urgent and I must be leaving!"
"What about Merida!?" Flynn asked.
"Well…" Rupert turned to all his suitcases, looked at them, seeing if they were closed, and turned back to the kids. "I am sorry that has happened and it is very unfortunate."
"You can't leave!" Jack yelled. "You're the Defense against the Dark Arts teacher!"
Rupert slammed an article of clothing into a bag. "When I took this job, there was nothing in the description about", he went around his desk to leave –
All the kids stood in front of him.
"You're running away!?" Rapunzel asked, directly in front of Rupert. "What about all those fights in your books?"
"Books can be misleading!" Rupert retorted.
"You wrote them!" Astrid stepped next to Rapunzel.
"Use common sense!" Rupert yelled. "My books would not have sold as well as they did if people knew I didn't do those things."
Flynn and Rapunzel gasped.
"You're a fraud." Kristoff said.
Jack reached into his coat, pulled out two gold coins, and handed them to Astrid.
Astrid looked at the coins and then to Jack. "You were carrying those?"
Jack shrugged. "Always prepared."
Rapunzel shook her head and looked back at Rupert. "You've been taking credit for what other witches and wizards have done?"
Rupert rolled his eyes. "Nothing gets past you bunch."
"Is there anything you can do?" Flynn asked.
"There is." Rupert smiled. "I'm highly gifted at Memory Charms. If I wasn't…all those other wizards would have gone blabbing." He started to walk over to some of his cases. "In fact – I'll have to use my skills on you all." He turned with his wand and was faced with five wands.
Astrid shook her head. "Put it down."
Rupert dropped his wand.
After a while, the six of them came into Aggrieved Aggie's bathroom.
"Who's there?" Aggie turned to all of them. "Oh." She smiled. "Hi you guys." She waved happily, then she realized… "Is there something you all need?"
Rapunzel stepped forward. "Can you tell us how you died?"
Aggie looked down sadly. "It was awful. It happened right here in this stall." She pointed down at the stall she was floating over. "I was being bullied for no reason by senior students, so I hid in here. I was crying, but then I heard someone come in."
Rapunzel tilted her head a bit to the side. "Who was it?"
Aggie began to whimper. "I don't know!" She started to float down to them, seeming to calm down. "But I heard them speaking a weird language – then I realized it was a boy. So, I unlocked the door to tell him to go away and I died." She stopped in front of Rapunzel.
"Just like that?" Jack asked. "How?"
Aggie shrugged. "I remember seeing a pair of large yellow eyes. Over there by that sink." She pointed at the one sink with rust under the faucet and then floated away.
Jack, Kristoff, and Flynn began to inspect the sink.
Kristoff smiled and pointed to his side of the faucet. "This is the entrance to the Chamber of Secrets."
They all stood behind him, except for Astrid and Rupert, and saw a snake engraved on the faucet.
Rapunzel smiled at Astrid. "I do believe this will require your expertise."
Flynn pointed his wand at Rupert; Astrid cleared her throat and stood in front of the sink.
Astrid stared down the sink and then spoke in Parseltongue.
The top of the sinks went up to the ceiling, the sinks spread apart, and then the sink with the engraved snake went into the floor.
Rupert leaned over and looked down the chasm, gulped, and stood back with the kids. "Excellent job, Astrid." He smiled. "Now, there's no need for me!" He went to run away, but they all stopped him.
"Yes there is!" Rapunzel yelled and pushed him, almost down the chasm.
Rupert held onto the two sinks he was in between and stared at the kids in fear.
They all pointed their wands at him and said simultaneously: "YOU FIRST."
"What good will that do?" Rupert asked.
Flynn shrugged. "Better you than us I suppose."
Rupert nodded and turned to the chasm, looked down, and then faced back to the five. "You sure there's no other way to test this?"
Jack kicked Rupert down the chasm, but he didn't fall for long until they heard a crash.
Rupert groaned loudly in disgust. "It's filthy down here!"
Rapunzel shrugged. "Let's go."
"By the way." Aggie caught their attention. "If any of you die down there – you're welcome to share my toilet." She then giggled.
"Thanks?" Kristoff shrugged.
They all jumped down one-by-one screaming as they slid downward! When they hit the bottom, they landed on tiny skeletons, quite possible mice or rats.
Flynn looked at one of the skeletons. "Glad I keep Mr. Scabbers in his cage."
Jack bumped Flynn's arm and the five quickly stood and pointed their wands at Rupert.
"Remember", Astrid started, "if you see any sign of movement – close your eyes." She turned and walked through a pipe and Rapunzel immediately followed.
Jack gestured for Rupert to follow along; he did so – and the three boys followed behind him.
A few minutes later, Astrid led them all into a narrow area; the floor covered in sand and a large snake skin trailing along the floor.
Rapunzel, Flynn, and Kristoff walked next to the snake skin, inspecting it.
"What's that?" Jack asked, standing behind with Rupert and Astrid.
Astrid knelt down and touched the skin. "It's snake skin."
As Flynn reached the head of the skin, he said: "This thing must be at least 70 feet long."
Rapunzel lightly giggled. "Imagine if my hair was that long."
The others laughed a bit at her joke; and Rupert fainted.
Astrid shook her head at the fallen man. "Heart of a lion."
Rupert quickly sat up, grabbed Jack's wand, stood, grabbed Jack, and pointed the wand at him. "It ends here. Don't worry – everyone will know this story. I was too late to save the girl and you all lost your minds when you saw her dead." He then pointed the wand at Astrid. "Say goodbye to your memories, Ms. Hofferson. Obliviate!" The spell backfired against Rupert, freeing Jack, and sending Rupert against the stone wall behind him!
The ceiling began to shake loudly and many rocks fell between the five preteens, completely covering any space for them to get around – separating Jack and Astrid from the others and the rest of the area.
"Eugene!" Jack yelled. "Eugene!"
Flynn ran up to the rocks. "Jack! Jack, are you okay?"
"I'm fine!" Jack replied.
Astrid scoffed. "We're both fine!"
Rupert sat up with a groan, smiled at Jack, and said: "Hello. Who are you?"
"Um…" Jack looked at Astrid and then back to Rupert. "Jack Frost."
"Really?" Rupert asked. "And who am I?"
Astrid's eyebrows raised and she turned to the rubble. "Rupert's charm backfired on him and now he can't remember a thing!"
Kristoff rubbed the back of his neck. "Was anyone really worried when he grabbed Jack's wand?"
They all stood there for a second…shrugged, shook their heads, and said: "NO."
"This is quite the place." Rupert picked up a rock, smiled, and turned to Jack. "Do you live here?"
Astrid took the rock from Rupert and hit him across the head with it!
"Astrid just knocked him out!" Jack told the others.
"I did!" Astrid confirmed it proudly.
Jack groaned into his hand. "Now what!?" He asked exhaustedly.
"You two stay here!" Rapunzel told them. "Try to move these rocks so we can all get through together and we will go and get Merida."
"Good." Jack nodded.
Rapunzel, Flynn, and Kristoff went ahead just a few feet and saw a round door covered by metal snakes.
"Uh, Astrid!" Flynn yelled.
"Yeah!?" Astrid said.
"We may need you to say something in Parseltongue!" Kristoff said.
Astrid moved a rock and saw the door. "Okay." She put her wand against her neck, spoke loudly in Parseltongue, and the door opened with a metal snake going around the circle – making the others move back.
The door opened slowly and loudly, the three walked into the Chamber with their wands ready.
The Chamber was lined with a tiled walkway, all the way to a statue head of what could be Salazar Slytherin, with a pool of water in front of it, and more of the walkway around the pool. The walkway had water on both sides of it and open mouthed snake head statues on the water.
As they walked ahead; Rapunzel saw the diary.
"The diary!" Rapunzel ran to the diary and picked it up, shaking the water off of it.
When Flynn and Kristoff made it to Rapunzel, Flynn turned to his left, and saw a boy a bit older than them come from an opening in the wall.
"Who're you?" Flynn asked the boy.
Rapunzel looked at the boy and stood. "Dustin Babcock. Are you a ghost?"
Dustin walked up to them. "A memory…kept in that diary for 50 years."
Kristoff looked around. "Where's Merida?"
Dustin walked between the three kids and the large statue head, pointing Merida's wand at Rapunzel.
Flynn and Kristoff pointed their wands at Dustin.
Rapunzel stood. "Why do you have Merida's wand? Where is she?"
Dustin smiled. "You're looking at her – well…sort of." He then chuckled.
Kristoff went to say something, but Dustin held up his hand to stop him.
"I had Merida open the Chamber of Secrets, I had her command the Basilisk to attack your friends and that filthy cat, and I had her write those threatening messages on the walls." Dustin grinned.
"How?" Rapunzel asked.
"I am quite charming when it comes to young girls." Dustin winked at Rapunzel; and Flynn quickly stepped in front of her, causing Dustin to laugh. "Oh my, but she was in somewhat of a trance. She didn't completely know what she was doing, but she began to fear the diary and tried to rid herself of it in the girls bathroom – and who should find it, but one of you nine?"
Flynn took a step forward. "How are we looking at Merida's body when all we see is you?"
"Because I have taken over her body with the bond that her and I share with Drago!" Dustin wickedly smiled. "In fact, you all share some bond with Drago…I just don't know how."
"How do you know we have a bond with him?" Rapunzel asked. "And how do you know about him or even have a bond with him?"
"When Merida and I were bonding and I allowed you to see into my memory." Dustin winked at Rapunzel. "I saw and heard yours and her memories as well. Though the ones about Drago were fuzzy, short, and few – but I allowed you to see my memory a clear as day."
Kristoff stepped next to Flynn. "Why do you care so much about Drago?"
Dustin turned, wrote in the air with Merida's wand, spelling out in red words: 'Dustin Charming Babcock'. He then scattered the words and they then spelled out, with some of the letters fading away: 'I am Drago'.
"The heir of Slytherin." Flynn whispered.
Dustin turned to them. "After my current Headmaster began to suspect me of opening the Chamber, I preserved this memory of my sixteen year old self so I could lead someone to finish Salazar Slytherin's task! I used my diary to gain your trust, Rapunzel. To switch the blame on Gobber."
Kristoff stormed to Dustin, but Dustin threw Merida's wand against Kristoff's face, cutting his cheek, and stopping him – and Merida's wand came back to Dustin.
Rapunzel looked at the statue behind Dustin, smiled, and stood in front of Flynn and Kristoff. "Seems you have failed to rid the school of all Muggle-borns."
Flynn then swatted her across the back of her head.
Dustin chuckled. "Haven't you realized? My new target is you nine." He furrowed his brows at them.
"Why!?" Kristoff asked.
"Because!" Dustin yelled. "Whatever this bond is you have with my older self, I'm sure he does not want it, and instead wants you all dead."
Then they all heard a loud chirp, Rapunzel quickly turned, and saw Phil the Phoenix flying towards them with the sorting hat in his talons.
"Phil!" Rapunzel yelled with a wide smile.
Phil flew towards Kristoff, dropped the sorting hat into his arms, and flew back towards the entrance.
"That!?" Dustin practically laughed. "THAT is what you three are given to fight me!? A lousy songbird and an old hat!" He started to laugh hysterically. Dustin quickly turned to the statue head, put his hand out towards it, and spoke in Parseltongue.
The mouth of the statue slowly started to open…
