After few minutes Ron and Harry came downstairs.
"Chris? You wanted to tell us something?" Ron asked, looking very surprised.
"Yes. Did you know something?" Harry said
"Yeah. I know what's inside the chamber and who opened the chamber." Chris said quietly.
"What?" Ron almost screamed.
"Yes. Please. Don't freak out. It's... It's a Basilisk... the King of Serpents, gigantic size snake and can live many hundreds of years. That's why you can hear it Harry, because you're a Parseltongue and it can live without food for many years.... Spiders fear it that's why we saw the spiders running, from the places where people were petrified. ... and remember Hagrid told us that someone was killing his roosters, crowing of roosters are fatal to Basilisk..." Chris looked at the shocked face of Harry and Ron. "If someone looked at it's eyes through something then they got petrified, looking directly to the Basilisk's eyes results instant death but no one died because.."
"Because no one looked it straight in the eye. Colin saw it through his camera. The basilisk burned up all the film inside it, but Colin just got Petrified. Justin . . . Justin must've seen the basilisk through Nearly Headless Nick! Nick got the full blast of it, but he couldn't die again . . . and Hermione and that Ravenclaw prefect were found with a mirror next to them." Harry said with a realization.
"And I think, Hermione had just realized the monster was a basilisk and maybe she warned the first person she met to look around corners with a mirror first! And that girl pulled out her mirror..." Chris sighed.
Ron's jaw dropped.
"And Mrs. Norris?" he whispered eagerly.
"Remember there was water under Mrs. Norris." Chris explained.
"But how? If the snake was gigantic in size then how come no one saw it?" Ron asked.
"Because it was traveling through the pipes. Remember, Harry heard the sound from the walls... He said it was going up.. Because it was using the plumbing.."
"Then the entrance to the Chamber of Secrets!" Harry said hoarsely. "What if it's a bathroom?"
"Wait... Myrtle's bathroom!" said Chris surprised. "I didn't realise that. She told me once that she died in that bathroom when she heard some funny language.."
"Funny language?" Ron looked confused.
"Parseltongue." Harry and Chris said together.
"But you said, you know, who's that heir of Slytherin. So? Who is it?" Ron asked and Chris took a deep breath.
"It's... Ginny.." as Chris said, Ron almost stumbled back in shock.
"What? Chris, what are you saying..?" Harry said in disbelief.
"Ginny can't be." Ron gasped.
"How and why, I'll tell you both tomorrow.... Just know it's not her fault.... I convinced Ginny, we're going to meet Dumbledore tomorrow..... and Ron, please don't write to your mother right now. Do it tomorrow. Please."

However next morning, Professor Dumbledore was gone, so was Hagrid... and Ginny she was nowhere to be found.
Chris, Harry and Ron searched the entire Gryffindor tower, the Great Hall. At last they decided to tell a teacher.
"What're you three doing here?" Professor McGonagall asked with a fearful tone. She was almost white.
"Professor! Ginny, We're looking for her." Ron said.
"She's not in Gryffindor tower from this morning, Professor." Chris said.
Professor McGonagall face became more pale. "I suggest, you three to go back to the Gryffindor tower. Something terrible happened."
"Professor?" Chris was tensed.
"Mr. Weasley. Your sister has been taken... to the chamber... by the monster... We'll try our best to save her." Professor McGonagall said with a cracked voice.
Ron slide down onto the floor. Harry helped him to stand up.
After Professor McGonagall almost dragged them into the dormitory and told the Gryffindors what have happened to Ginny; Chris, Harry, Ron, Fred and George was sitting together in a corner of the Gryffindor common room, unable to say anything to each other. Percy wasn't there. He had gone to send an owl to Mr. and Mrs. Weasley, then shut himself up in his dormitory.
Chris's face was expressionless. It was like the emotions inside her were so many and so much that her face was failing to express them.
"Now, will you tell us the entire thing, Chris?" Ron spoke for the first time after he heard the news.
Chris sighed then took a deep breath and straighten up in her chair.
"Yes. I'll. It was a Diary. The diary of a boy named Tom Riddle. He was the one who accused Hagrid... for opening the chamber and freeing the monster within... but Hagrid had a Acromantula, a giant spider.. Acromantula can't petrify. I realized something was wrong when I found Ginny throwing a diary in Myrtle's bathroom.. the diary of that same boy T. M. Riddle. I picked it up and started examining it. Then Harry said he felt connected to the Diary.... and when I wrote in that diary... it replied back. Tom Riddle was a memory inside the Diary.. I don't know how long but Ginny was writing in it and that's why she wasn't looked like herself... I don't know about all kind of magic, but I know, for that kind of magic, storing a part of yourself or your life in a object, needs very very very advanced magic and I won't believe a that kind of smart person will mistook between Acromantula and Basilisk.. then I remembered he was a Slytherin... Everything became clear.. Harry's connection to the snakes and that diary wasn't a coincidence.... Tom Riddle turned Hagrid in because he was saving himself. He was the one who opened the chamber last time and this time using Ginny. He was a Parseltongue too... The paint on Ginny's robes, roosters feathers in our room and on her things, and the writing on the wall matching Ginny's handwriting was enough proofs for me."
As she finished, she saw Fred, George, Ron and Harry were staring at her.
