If he was startled by his usually cold and distant mother's arms wrapping around his neck, Oliver didn't let on. He acted as if the tight squeeze she held him in for several long moments was perfectly normal behavior. Perhaps that was what he wanted from her all along. She'd seen how Mafalda and even Hannah hugged him. Neither woman ever appeared to be in a hurry to let go. Even if it was the only embrace he'd ever get from her like that, Hermione didn't fail him in that instance.
