Lord Voldemort has left Malfoy Manor, taking Dolohov with him, because of something Tristan Nott told him. Draco concludes that Theo’s father didn’t succeed in working out an alliance agreement with the wizarding communities in Romania and Bulgaria, so the Dark Lord has taken matters into his own hands. It’s a relief not to have him in the Manor, but now Draco has to deal with Tristan Nott, who is currently Voldemort’s favorite, despite his lack of diplomatic skills. Draco has to walk a fine line, reminding Nott that Lord Malfoy is the master of Malfoy Manor without provoking the man’s anger.
