"Well?" asked Marisa impatiently.
It was about one o'clock. As it was the weekend, there was no need to worry about getting up early the next morning, so they were free to stay up late in order to avoid Draco.
"Well what?" replied Leo, even though he knew perfectly well what she meant.
"Well, can you please explain what that was?"
"What what was?"
"You know exactly what," said Marisa, her patience running out. "What is the Chamber of Secrets, who is the heir, and what does this has to do with Draco."
"Well," said Leo, "the only one I can fully answer is the first. The Chamber of Secrets was created by Salazar Slytherin after a dispute between him and Godric Gryffindor. Rumour states that it holds a monster destined to," he made quotation marks with his fingers, "purge the school of those who are unworthy to study magic".
"And… that means Muggle-borns, right?"
"That's how most people have interpreted it, but it's not necessarily what Slytherin meant. But Slytherin's dead, so it's the intentions of the heir that matter."
"The heir… of Slytherin?"
Leo nodded.
"Who is this heir?" she asked.
"Well, if I knew that, this wouldn't be happening now. Would it?"
"Got any theories?"
"No, I'm not sure."
"Shall we investigate together?"
Leo hesitated. "We can ask around, but I don't think we should do anything stupid."
"When did I mention that?" asked Marisa. "You know that I am not stupid, and wouldn't do anything stupid."
"I'm just saying," Leo pointed out, "sneaking out to fly is one thing, tackling the thousand-year-old monster of Salazar Slytherin is quite another."
"I had no plans to tackle it," replied Marisa, "I just wanted to find out what it was. Anyway, I'd better get some sleep. See you tomorrow?"
"Yeah," Leo replied and stood up.
