In Harry Potter as Neville Longbottom

The poisonous fangs of Basilisk bit the diary and killed Voldemort instantly and destroyed the Horcrux. A white thin glowing line around the Basilisk suddenly started disappearing and the destruction of the Horcrux caused a small explosion inside Basilisk's mouth making it move crazily in pain.

Harry heard the serpent hissing in pain and tried to get cover under the platform but a large stone from the wall behind him suddenly (strangely) dropped on top of him. Harry passed out from the impact and was somehow his fainted body was safely tucked under the platform.

The serpent king Basilisk also suppressed his pain after some time and then looked around. Two large scratches near his right eye were still dripping blood and now there was some poisonous blood dripping from his mouth too. However, it was not attacking or killing anyone but hissing toward the Phoenix.

Fawkes flew in the air around the Basilisk, and both started a strange conversation of hissing and chirping. After some sort of argument or discussion, it disappeared inside a small fireball leaving the serpent king alone in the secret chambers.

"Fuck! What the fuck?" Neville who just saw this scene hiding inside the invisible cloak felt stupid. This was not the part of the script.

The great Harry Potter had already saved the day by killing Voldemort but where is the Old Headmaster? Where is Dumbledore? Should he not come here and take harry away killing this Basilisk?

How come that fucking fire chicken leaves without killing this fucking snake or rescuing the kids here?

Neville who was hiding behind another statue carefully felt his brain freezing. So many questions were staring Neville in his face and then he saw the serpent king coiling around on top of his statue.

It was staring dead into his eyes. Neville had no chance to avoid or close his eyes and he felt the one huge light-yellow eyeball was watching him closely.

However, Neville realised he was safe and still alive inside the invisible cloak, but he could see the face of Basilisk. He was not even petrified while he was having the staring constant with such a huge powerful and deadly beast.

"That was close!" Neville just had this thought when he saw Basilisk opening his mouth and then roaring in front of his cloak.

Neville felt terrified and moved a few steps back.

"Armour!" He shouted and the floating Grimoire released a glowing shield around him giving him some sort of confidence.

However, contrary to his expectations of the general monster movies, the Basilisk didn't attack Neville or Harry. It just sniffed closely for a few minutes and then turned his head away and slithered towards the giant snake's head.

Neville's eyes sparkled at the scene, and he had a dangerous glint in his eyes. When the Basilisk had just entered the mouth, a suitcase suddenly opened, and the serpent was simply sucked inside.

Neville had put his bag there to create a trap for the serpent king in case he ever tried to flee or if he himself needed to hide somewhere during the fight.

"Finally, something as per the script!" Neville shouted excitedly and took off the invisible robe.

Neville came out in open and saw that in the end, he was the only one standing like a true victor in the chamber of secrets. The Basilisk was trapped, Voldemort is dead and his Horcrux destroyed, and the culprit Daphne Greengrass who was also a victim herself, still alive and breathing.

But how to end this matter? Should he bring Harry and Daphne out from here? Or Should he send some sort of signal to the professors?

Finally, deciding to keep his name far away from this trouble, Neville picked the diary which had a huge hole inside it. Then he got a good idea.

After the Horcrux was destroyed, the pages of diary had blackened and there were many scribbles and scratches in some pages. Neville turned the diary to the middle part and used transfiguration to turn a stone into a quill.

Using the blood drops on the floor from Basilisk as ink, he wrote two words inside the diary 'Gaunt's Ring' and as the blood touched the diary it damaged and created more tiny holes in paper matching the diary's condition.

"Let's see Headmaster, how will you like my gift?" Chuckling Neville threw the diary near Harry and then threw Daphne's wand in some corner.

With this work done, Neville decided before leaving he should have a look around the chamber. Neville carefully entered the Basilisk's nest but found nothing except a pipe that was dripping water and few fishes were dropping down from the net that closed the pipe.

"Maybe that how he survived all these years. The lake is just above the chamber and the water and fish from it will keep falling inside."

However, apart from this, the entire chamber was empty. If there was anything stored here for future heirs of Slytherin, Voldemort had already taken away.

With some disappointment, Neville left the chambers with his suitcase covering himself tightly in the invisible cloak.

Let the great Harry Potter do his thing. Neville had enough fame in the first year. Besides, he still has a mouse trapped inside his manor. A trapped, hungry and locked up prisoner in a dark and empty space.

In Snape's classroom, Professor snape was writing some notes on his recent experiment on potions when he felt the death mark tingling.

Snape immediately pulled his sleeve to find the dark had faded a lot. In the last two years, this had happened thrice. Some tingling, some sensation and then the death mark will fade.

"Something happened..... Harry!" Snape was just thinking before he realised Harry Potter might be in some danger.

"Dumbledore..." Professor Snape ran for headmaster and just knocked his doors before the doors opened itself.

"Aaah Severus! Anything urgent. You don't look ready for tonight's party?" Headmaster Dumbledore dressed in rare regal clothes and proper attire asked the huffing and puffing professor.

"Where is Harry?" Professor Severus could only ask this when Dumbledore found his Phoenix returning suddenly.

"Fawkes, where did you run away my old friend?" Headmaster Dumbledore scratched his Phoenix neck while sending a big magical detection wave around the whole Hogwarts.

Closing his eyes and watching the scene like SONAR feedback, he noticed a strange and deadly anomaly.

"Second Flood, Girl's washroom. So, that's where you are..." Dumbledore opened his eyes and realised he finally found the clue to the legendary chamber of secrets.

"Let's go Severus. Let's check out what the founding wizard of your house left behind for us." Headmaster Dumbledore simply said and then he walked in a speed that didn't match his age.

While walking, he sent his Patronus Phoenix to call other professors and bring them to the second floor. In a short time, other professors who were getting ready or were already dressed for the party hurried to that place.

Everyone knew headmaster would only use his Patronus in emergency cases only.
