Harry and Ron think Draco Malfoy is the heir of Slytherin. They think his evil father, Lucius Malfoy, told him the family secret on how to get into the Chamber. But while they are under the Polyjuice potion as Crabbe and Goyle they find out that they are wrong.
Slytherin Common Room
This propels the action because Harry and Ron still don’t know who the heir of Slytherin is. This keeps the rumors going that Harry might be the heir. He thinks that it is impossible for him to be the heir because he doesn’t know anything about the Chamber but Hermione tells them there is not enough evidence that he isn’t. The entire school realizes that Harry is a “ Parseltongue” meaning he can talk to snakes during dueling club. This doesn’t help the rumors and scares first years because Slytherin was known for using his parseltongue against mudbloods and half- bloods. This is when they realize the monster or beast hiding in the Chamber of Secrets might be Slytherins serpent, this is why the Slytherin logo is a snake.
