Molly attacks
She ducks away from the body she has just felled, spinning around in time to see a green light flash centimeters from Ginny's – her Ginny's – leg. Her vision narrows.
She is a mother – of seven children! – made to nurture life, not to extinguish it.
But in that moment, bright-hot anger – red as the hair on her children's heads – coursing through her veins, any thoughts of the sanctity of life flee her mind. All that's left to focus on is the sick perversion of nature she is unfortunate enough to be related to.
