( May '98 )

Cassandra and Harry pushed past students as they ran up to Ravenclaw tower.

"Harry!" Luna called after the twins. "Cassandra! Wait! I need to talk to you."

"We're a bit preoccupied at the moment!" Harry told Luna.

"You guys won't find anything where you're going." Luna said. "You're wasting your time."

"Look, we'll talk later." Harry said. "Okay Luna?"

"Harry and Cassandra Potter, listen to me right now!" Luna yelled, causing the twins to face her. "Don't you remember what Cho said about Rowena Ravenclaw's Diadem? There's not a person alive who's seen it. It's obvious isn't it? We have to talk to someone who's dead."

Harry and Cassandra followed Luna to another part of the castle.

"If you want to find her, you'll find her down there." Luna said, pointing.

"Aren't you coming?" Cassandra asked.

"No." Luna said. "I think it's best if you three talk alone. She's very shy."

"You're the Grey Lady." Harry said. "The ghost of Ravenclaw tower."

"I do not answer to that name." Helena said, gliding away from Harry.

"It's Helena, isn't it?" Cassandra asked. "Helena Ravenclaw, Rowena's daughter?"

"Are you two friends of Luna?" Helena asked.

"Yes, we've been friends with her for quite some time." Cassandra answered.

"She thought you might be able to help us." Harry added.

"You see my mother's diadem." Helena said.

"Yes." Cassandra said. "That's right."

"Luna is kind." Helena said. "Unlike so many of the others. But she is wrong. I cannot help you."

"Wait!" Cassandra called. "Please."

"We want to destroy it." Harry said. "That's what you want too, isn't it Helena? You want it destroyed."

"Another swore to destroy it many years ago." Helena said. "A strange boy with a strange name."

"Tom Riddle." Cassandra whispered.

"He lied." Helena said.

"He is right outside these castle gates." Cassandra said. "He is about to kill anyone who doesn't listen to him or give him what he wants. The diadem is a horcrux and once we destroy it, part of his soul gets destroyed too."

"You two remind me of him a bit." Helena whispered. "It's here in the castle. In the place where everything is hidden. If you have to ask, you'll never know. If you know, you need only ask."

"Thank you!" Cassandra said.

Cassandra and Harry ran off. They headed down a staircase that was in almost complete ruin.

"Ginny!" Harry yelled. "Neville! Are you alright?"

"Never better." Neville answered. "I feel like I could spit fire. You haven't seen Luna have you?"

"Luna?" Cassandra asked.

"I'm mad for her!" Neville said. "I think it's about time I told her, since we'll both be dead by dawn!"

"Awww." Cassandra cooed.

Beside her, Ginny and Harry latched in a kiss. She heard Ginny mention something to Harry before she ran off. Harry grabbed Cassandra's hand and they ran.

They reached the Room of Requirement. The door disappeared behind them as they stepped in. They took a look around before getting the diadem.

"Too bad we don't have the basilisk fang." Cassandra said before the diadem was knocked out of her hands. "Shit."

The diadem was on a tall stack of junk.

"Well, well." A voice from behind them said. "What brings you here, Potters?"

Cassandra turned around and was met face to face with Goyle, Draco and Blaise.

"We could ask you the same." Cassandra said, crossing her arms.

She knew that today would determine where Draco's loyalty lies.

"You have something of mine." Draco stated. "I'd like it back."

"What's wrong with the one you have?" Harry asked.

"It's my mother's." Draco said. "It's powerful, but not the same. Doesn't quite understand me. Know what I mean?"

"Expelliarmus!" Hermione yelled.

"Avada Kedavra!" Goyle yelled and the spell hit an object.

"Stupefy!" Hermione yelled.

Blaise and Draco ran off with Goyle behind them and Ron chased after them.

"That's my girlfriend you numpty!" Ron yelled.

"Girlfriend?" Cassandra asked as she started to climb the stack of objects.

Cassandra saw Hermione blush out of the corner of her eye. Cassandra attempted to use her "scarlet witch" magic to get the diadem down but she was weak and unsuccessful. She managed to get to the diadem and climb down before chaos broke out. She joined Harry and Hermione on the floor and a yellow light was coming from where Ron ran to.

"Aaahhhhh!" Ron yelled, coming out of the area. "Goyle set the bloody place on fire!"

The fire had taken the form of a snake and the four young Gryffindors had started running away. Harry and Cassandra knocked things down as they ran past. They all managed to escape the fire before it appeared again. Ron tripped and fell back into a pile of brooms.

They each mounted a broom and zoomed off in time to see Goyle fall to his death. Draco and Blaise looked horrified as they continued climbing up a stack of junk.

"We have to help them!" Cassandra yelled.

Harry nodded in agreement before taking Blaise. Cassandra went and got Draco. Draco wrapped his arms around Cassandra's waist, earning a blush from her. Her body felt like fire which was kind of ironic in that situation. They flew out and tumbled onto the floor. Draco was on top of Cassandra. He quickly moved off of her and he was now blushing as well.

"Hermione! The fang!" Cassandra exclaimed.

Cassandra took the fang, lifting it above her head, and smashed the diadem. She grabbed onto Draco as she felt a sharp pang hit her chest. She kicked the diadem into the Room of Requirement before the doors had closed. She started having a vision of Nagini and she immediately knew that the snake was the last horcrux before she would meet her end.

Draco placed Cassandra near a wall before disappearing down the hallway with Blaise.

"It's the snake." Cassandra said. "She's the last one. She's the last horcrux."

"Look inside him." Ron said. "Find out where he is, if we find him we find the snake. And we can end this."

Cassandra nodded before closing her eyes. She saw a boat and then Nagini. Right beside Nagini was Voldemort and Lucius.

"My lord, might it be less..." Lucius trailed off. "I could not be more prudent to call off this attack. Simply seek the twins yourself."

"I do not need to seek the boy and girl." Voldemort said. "Before the night is out, they will come to me. Do you understand? Look at me. How can you live with yourself Lucius?"

"I don't know." Lucius answered.

"Go and find Severus." Voldemort said. "Bring him to me."

"Shit shit shit!" Cassandra cursed.

"What's wrong?" Ron asked.

"I know where he is." Cassandra said. "But he's going to kill Snape."
