Ginny Weasley.
Ginny Weasley.
To save Ginny Weasley.
It saves by it self
As well as saving all the lives of the 'Mudbloods' in Harry Potter and the Chamber of Secrets he saved the life of Ginny, Ron's younger sister and the youngest in the Weasley Family.
Ginny is his best-friend's sister and an eleven year old girl, he wasn't going to let her die.
In the English version of the Chamber of Secrets with 251 pages i'd say the climax is on page 104 when Harry, Ron and Hermione (well Harry) hears the voice in the walls and they they find Mrs. Norris petrified.
It depends on what you like. The Sorcerer's Stone starts off calm as Harry finds out who his real friends are, Ron and Hermione, then the action starts as they get into trouble and try to figure out the secrets of the stone then as they fight Lord Voldemort. The Chamber of Secrets is more exciting at the beginning and near the end it's a little exciting but mainly the tension packs on as Harry is trying to save the muggle-borns and Ginny's life from Voldemort.
Tom Riddle* and Harry both meet face to face in the Chamber of Secrets (book & film 2) when Harry is trying to save Ginny. However, earlier in the film there is a flash back into Riddle's diary, where Harry does see him, but its merely a memory, so Riddle doesn't see him.
Arogog is Hagrid's pet. It is a giant spider that was blamed for terrorizing Hogwarts School 50 years earlier. In order to save Arogog's life, Hagrid released the spider into the forbidden forest and later found him a mate. Hagrid still visits Arogog and loves him dearly. Arogog is introduced in Harry Potter and the Chamber of Secrets, and makes a major plot twist in Harry Potter and The Half Blood Prince.
Yes, Harry saves Ginny from the Chamber of Secrets and Tom Riddle in the 2nd book. Tom Riddle is what Voldemort's birth name is, and in this case he is the soul/memory that lives in Tom Riddle's diary. (The reason Ginny is in the Chamber of Secrets is because she poured her thoughts into the diary, which got her dependent on the diary, the part of Tom Riddle in the diary took her over and used her to open the Chamber of Secrets and control the beast of the Chamber of Secrets). He saves her by stabbing the Basilisk fang into the diary (which is also a Horcrux of Voldemort's).
because harry potter save ginny from Voldemort
In Harry Potter and the Chamber of Secrets he attempts to stop Harry Potter from going back to Hogwarts by dropping a cake on top of the Dursley's visitor and blocking the barrier to the platform. He then attempted to get him sent home by charming a bludger to follow him. At the end he protects him from Lucius Malfoy. In Harry Potter and the Goblet of Fire he steals Gillyweed from Severus Snape's store cupboard so that Harry can save his "Wheezy" (Ron Weasley) from the lake challenge. He also starts working at Hogwarts and looks after Winky. In Harry Potter and the Order of the Phoenix he tells Harry about the Room of Requirement and tells him when Umbridge is coming. In Harry Potter and the Half-Blood Prince Harry asks him, along with Kreacher, to spy on Draco Malfoy. Dobby fought Kreacher when he insulted Harry. In Harry Potter and the Deathly Hallows he saves Harry, Ron, Hermione, Luna, Ollivander and Griphook from Malfoy Manor and died after being stabbed in the heart by Bellatrix Lestrange's knife.
