Narcissa wasn't one to have nasty habits like biting at her nails or gnawing at her thumb or tugging at her hair, though she did have lapses and always blamed them on this Muggle infested and filthy city.

Narcissa moved her arms to embrace him, but hesitated, in the unlikely event he wouldn't want the contact.
