"What lingering Death Eaters?" Narcissa asked him. She knew of a few names, if she was honest, but only a few, and only she and Draco had received pardons.
And Draco thought Regulus was similar to himself. He had absolutely no idea. And Narcissa instantly knew it would be dangerous to let them spend too much time together. Whatever her choices had been in the second war, whatever Draco's had been, Regulus' influence on her son had to be controlled.
"Leave him to me as well," she decided. Up until his defection, she'd had quite a bit of influence over him, and she couldn't imagine that vanishing now. "But we have to keep him out of Lucius' way, or Merlin knows what will happen ..."
The situation had suddenly become much more complicated, but it was probably a blessing. Narcissa couldn't dwell on memories any longer, not when she had to actively manage a difficult, potentially dangerous situation.
