So I'm not totally farmilar with the books or movies but I'm going to try to fit it in as best as I can. Enjoy.
Unfortunately, Danny had to spend his detention with Professor Lockhart. To good thing is that he didn't have to sit and help sign the pig of wizard's fan mail alone. For some reason, Harry was a signed detention too. When their time was done both boys hurried out of Lockhart's chambers. On the way to the dorms, they ran into Ron and Hermione. Together they walked the long halls to the Gryffindor tower, but a side trip happened after Harry declared he heard a voice when Danny, Hermione and Ron heard nothing. The three Gryffindors followed Harry until they came across a very disturbing sight.
Hogwarts' caretaker Argus Filch's cat, Mrs. Norris, was hung up side down petrified, and a message written in blood;
The chambers of serects has been opened. Enemies of the heir, beware...
After a long discussion, it was mauled over that the four came to be at the wrong place at the wrong time.
The next morning during Transfiguration, the group talked about the events that happened the night before.
"What could the chambers of Secrets be?" Danny shrugged his shoulder at Ron's question.
Hermione turned her hazel eyes from her male friends to Professor McGonagall. "Professor," the wild, curly brunette called as she raised her hand. "Can you tell us about the chambers of Secrets?"
At first Professor McGonagall seemed put back at the knowledge that they know about the chamber but explains anyway, that one of Hogwarts' founders, Salazar Slytherin, supposedly constructed a secret Chamber and placed inside it a monster that only his Heir can control, to purge the school of impure-blooded wizards and witches. Since Mrs. Norris' attack many more attacks occur over the course of the year. Danny, Harry and Ron suspect Malfoy is the Heir, so Hermione suggests they question him while disguised using polyjuice potion. Their makeshift laboratory is in a disused bathroom haunted by a ghost, Moaning Myrtle.
When Harry communicates with a snake, the group realized that was something Salazar Slytherin could do as well. Most of Hogwarts believe Harry is the Heir. At Christmas, Harry and Ron learn that Malfoy is not the Heir, but he mentions that a girl died when the Chamber was last opened fifty years ago. Harry finds an enchanted diary, owned by a former student named Tom Riddle, which shows him a flashback to fifty years before, where Riddle accused Hagrid, then a student, of opening the Chamber. When the diary disappears and Hermione is petrified, Harry, Danny and Ron question Hagrid. Professor Dumbledore, Cornelius Fudge, and Lucius Malfoy come to take Hagrid to Azkaban, but he discreetly tells the boys to "follow the spiders".
Lucius has Dumbledore suspended. In the Forbidden Forest, Danny, Harry and Ron find Aragog, who reveals Hagrid's innocence and that the dead girl was found in a bathroom. Aragog then sets his colony of Acromantula on the boys, after calling for their brooms and riding off to the castle saves them.
Once back in the castle they three boys find that Hermione has been the recent victim. A book page in Hermione's hand reveals the monster is a basilisk, a giant serpent that instantly kills those who make direct eye contact with it; the petrified victims saw it indirectly.
"That explains alot." Danny mumbled but Harry and Ron heard him. "What are we going to do?"
Ron raised his hands and shook his head. "I am not going anywhere near a killer snake."
Harry and Danny understood before going to investigate and question Myrtle. On the way to Myrtle's bathroom they come across another writing, with the school staff surrounded. The school staff learn that Breana was taken into the Chamber, and convince Lockhart to save her.
"Breana!" Danny cried in despair. Danny had tears as he thought about Breana down in the chamber with a killer snake.
Harry covered his friend's mouth so they wouldn't be discovered, after all it was against the new rules to be out this late. "We'll find her."
After nodding, Harry and Danny find Lockhart, revealed as a fraud, planning to flee; knowing Myrtle was the girl the Basilisk killed, they drag him to her bathroom and find the Chamber's entrance.
Before sliding down the sink after Danny and Lockhart Myrtle called out and said, "If you die, we can share my toilet."
Harry shook his head before jumping down the opening. Once inside, Lockhart uses Danny's wand against them, but it backfires, wiping his memory, and causes a cave-in.
Harry enters the Chamber alone and finds Breana unconscious and dying guarded by Tom Riddle. Harry realises Riddle is the Heir and he used the diary to manipulate Breana and reopen the Chamber. Riddle then reveals his full name, Tom Marvolo Riddle, from which he created the anagram for his future new identity, "I am Lord Voldemort".
After Harry expresses support for Dumbledore, Dumbledore's phoenix Fawkes flies in with the Sorting Hat, and Riddle summons the Basilisk. Fawkes blinds the Basilisk, and the Sorting Hat eventually produces a sword with which Harry battles and slays the Basilisk, but he is poisoned by its fangs.
Harry defeats Riddle and revives Breana by stabbing the diary with a basilisk fang. Fawkes' tears heal him, and he returns to Hogwarts with his friends and a baffled professor Lockhart. Dumbledore, reinstated as headmaster, praises them and orders for Hagrid's release. Dumbledore shows Harry that the sword he wielded was Godric Gryffindor's own sword, and says he is different from Voldemort because he chose Gryffindor House instead of Slytherin House. Harry accuses Lucius, who he found out was Dobby's master when the two appeared in Dumbledore's office, of putting the diary in Breana's cauldron and tricks him into freeing Dobby. The Basilisk's victims are healed, Hermione is reunited with Harry and Ron and Hagrid returns to school.
The Burrow
Molly Weasley was overly concerned when she, Arthur and Remus got the news about what happened at Hogwarts. But she was calmed and happy after seeing the group of children she cared for so much returned unscarred, but not all was undamaged. As Tom Riddle didn't do much as of take over Breana's mind, it was something that she would never forget. Even if the whole household pretend that it never happened. Danny on the other hand, tried his hardest to come to terms of what happened. He could of lost his love of his life, and didn't even tell her. But he didn't know how?
While Danny and Breana was getting through their tumours, there was a problem that the adults also known as the Order of the Phoenix had to deal with.
"When did he get out?"
Arthur, who works with the Minstery of Magic was the one to receive such grave news. He rubbed his wife's shoulder as he shook his head. "They don't know."
Molly sobbed which rocked her whole body. "That poor boy. He has so much on his shoulders...now this!" During Molly's outburst she threw a issue of the Daily Prophet across the table.
Tonks shared a look at her grum looking husband before looking at the paper on the kitchen table that showed a bit of movement.
Have you seen this Wizard?
Underneath was a picture of a wizard the Order knew all too well, with a Prisoner of Azkaban sign, after all he was one of them.
