Harry runs out of the exam hall to get help. Unfortunately, Professor [=McGonagall=] is not in school. Due to her injuries in the previous chapter, she has been taken to St Mungo's Hospital. Harry finds Ron and Hermione. An argument ensues with Hermione, who says it could be a trick by Voldemort. They are joined by Ginny and Luna. They agree to a plan to check whether Sirius is being held captive. Harry will access Grimmauld Place using the Floo Powder and the fireplace in Umbridge's office while the rest of them create a diversion.

While the others create the diversion, Harry goes into Umbridges office and uses the fire to again look through into Grimmauld Place. Only Kreacher is there. He tells Harry that Sirius has indeed been taken captive. Umbridge then grabs Harry and drags him back into her office. It turns out that she had added extra protective spells in the office and that in any case, the others' diversion plan failed. The Inquistorial Squad bring in Harry's four accomplices as captives, as well as Neville.

Umbridge demands Harry tell her who he was trying to contact. She summons Snape and demands Veritaserum to interrogate Harry. Snape tells her that she exhausted all of it and it would take a month to make more. Harry tries to tell by telling him cryptically that "He's got Padfoot in the place where it's hidden!" Snape does not seem to understand, and leaves. Umbridge tells Harry she will use the Cruciatus Curse to get information from him. She tells a protesting Hermione that she is not concerned that it is illegal if no-one finds out, revealing that she was the one who sent the Dementors [[Recap/HarryPotterAndTheOrderOfThePhoenixC1DudleyDemented in the first chapter]].

Hermione stops Umbridge by making a false confession up on the spot. She says that there is a "weapon" hidden in the school grounds and Harry was trying to tell Dumbledore that it is ready. Umbridge agrees to go alone with Harry and Hermione to be shown the "weapon".
