Harry Potter & the Half Blood Prince SPOILER ALERT!
Chapter Twenty-One: The Unknowable Room
Synopsis
Kreacher and Dobby report to Harry that Malfoy has been frequenting the seventh floor with variety of other students who keep watch for him while he enters the Room of Requirement.
Harry realizes that the variety of students are just Crabbe and Goyle who have been taking Polyjuice Potion to change their appearance.
From the Daily Prophet, they find out that Mundungus has been sent to Azkaban.
Moaning Myrtle has been visiting the boy's bathroom and tells Harry and Ron that she has been talking to someone in there.
Harry tries to get into the Room of Requirement but fails. Instead, he sees Tonks by the hallway.
Ron and Hermione take another class prior to their Apparition tests.
I wonder who the crying boy talking to Moaning Myrtle is.
And, as we can all expect, I think that Ron and Hermione will end up together.
