Harry, Ron, and Fang are picked up by [acromantulas] and carried to Aragog. Aragog explains that he was not the monster from the Chamber of Secrets, the monster that killed a girl in the bathroom. He then tells his family to devour Ron and Harry, who escape only with the help of Mr. Weasley's car.

Back in Hagrid's hut, Harry and Ron discuss the [acromantulas] and catch their breath before heading up to their [dormitory]. Just before falling asleep though, Harry realizes that the girl killed by the monster 50 years before was probably Moaning Myrtle.

At breakfast Professor McGonagall announces that the [Mandrake Restorative Draught] is almost ready, to an excited student body. Ginny comes over, scared, and tries to tell them something but is scared away by Percy.

While they are led to class by Professor Lockhart, Harry and Ron convince him to let the class go on themselves - and leave the class straight for Moaning Myrtle's bathroom.

McGonagall catches Ron and Harry in the hall, and they tell her they were trying to see Hermione. She is moved, and lets them go.

Harry and Ron run up to the hospital wing to see Hermione, to Madam Pomfrey's displeasure. Once there, Harry finds a page of a library book in Hermione's hand, explaining the [basilisk], and figures out that it's [Slytherin's monster], and how all of the pieces fit together - including the fact that the entrance to the chamber is in [Moaning Myrtle's bathroom] - and run off to find McGonagall.
