Molly & Draco
Hate was a strong word for someone like Molly, who tried her hardest to be kind to everyone. Even the Slytherins at school, many of whom she felt were too snobby or rude. Even when people disagreed, Molly would be inclined to strive for peaceable resolution of issues. Hearing that her Arthur and Draco's father hated one another was worth the deep frown that appeared on her face. Sociopolitical ideologies were one thing, but hate felt very personal.
Hearing that she supposedly killed someone distracted Molly from everything said thereafter. She barely registered the name of Remus Lupin when the name Lestrange and being Draco's aunt drew her attention. It was unsurprising that the Malfoy family and the Lestrange family were connected. Both were pureblood families of long magical lineage.
"What?!" The red-haired witch looked shocked beyond measure. "Surely you must be mistaken. I couldn't possibly kill anyone!"
