Severus Snape prepares Harry for a new Defence professor from the Ministry, Dolores Umbridge, and warns him to keep his head down. A tense departure from Prince Manor leads to Grimmauld Place through the Fidelius Charm, where Harry meets the Weasleys and finally confronts Ron and Hermione about a summer of silence. What follows is a raw, shouting match about secrecy, trust, and Dumbledore’s choices, with Snape’s practical guidance echoing in the background. This is close, character-driven guardianship that sets the stakes for Order of the Phoenix.
