Narcissa's lips flew up into a smile upon hearing Tom's admittance of not being a Muggle, more than sure of the fact after seeing his wand. "Thank Merlin for that, yes?" She shot a look at Logan, blowing air out of her nose and dismissing him by focusing once more on the young man before her.
She had not yet drawn her wand, seeing no use for it as he posed no threat. She kept her gaze relaxed and her stance was elegant, measured. There was no lazy slouch or fidgeting of the hands.
She was having difficulty placing those eyes and waited for some revelation of who he was, because he apparently knew her as well. "I am..." she drew a breath to say more, but thought better of it and started again. "May I ask whom I have the pleasure of speaking with?" She treaded carefully in the event he was foe and not ally.
