Voldemort is in residence at Malfoy Manor again, and Draco feels sick most of the time. If the Dark Lord is there, so are his field commanders, Dolohov and Yaxley, who are worse even than Rabastan and Rodolphus because they’re not as stupid. Draco’s first goal on his return to his family home has been to establish himself as Lord Malfoy. This is his ancestral home; he is the sole heir of the Malfoy family, and he will manage his home as he sees fit. As much as possible, he emulates his father, but, unlike his father, he doesn’t abase himself before Voldemort. He treats the Dark Lord with deference, of course, but this is the Malfoy estate, not Tom Riddle’s house, and Voldemort is a guest in it. Voldemort misses Lucius’s obsequious toadying, but Draco now holds the rights to the Malfoy vault, and an army needs supplies. It won’t do to offend young Lord Malfoy if he doesn’t have to. For now, it is an acceptable arrangement. If it becomes burdensome later – well, Nagini is always hungry.
