An accident?! Mrs. Malfoy knew there was no mistake made. Andromeda had been jealous of the Malfoys from the day Lucius chose his true wife. Mrs. Tonks was clearly driven to this unforgivable act by the loss of her own Mudblood sack of flesh husband getting himself killed. Because of Andromeda's own foolishness, she had lost everything, and wanted nothing more than to make sure her prosperous sister fell, too.
Narcissa did not speak another word to Andromeda. Of course she was going to take her husband away! The murdering bitch suggesting it was condescending and wretched... as if Narcissa could not think of it on her own! As if Narcissa would allow her precious, perfect treasure of a husband remain in the shadow of such a repulsive disgrace!
The wench killed her husband and now she was going to act superior. People were staring. Mrs. Malfoy would have none of it. The blonde dug her nails into her husband's robes, her own face mangled with raw blotches and acidic tears. The pangs of her icy stare continued to cut into Andromeda, and hung in the air even after Narcissa had Apparated away with Lucius.
