Hermione was able to push aside all of her concerns about staying in Draco's flat for another day. When she practically ran from Kingsley's flat, there wasn't even a hesitation on her part to return. She felt safe when she was inside its walls, something she hadn't experienced since she was in Cornwall with her husband, her ex-lover and her son. It might have been wrong to return and continue to live in the confusion, but she didn't care. She just wanted one more day of safety.
