Lucius smiled at the child, looking her over. 'Well thank you,' he said with a chuckle, lifting the girl up into his laugh. 'Just don't tell granny Cissa that,' he said with a wink.
'You have very pretty hair yourself, just right for a Malfoy,' he told her, because though she may not be a true Malfoy she was one all the same.
'Now Violet, I know we've just met, but would you do something for me?' he asked softly, still from the corner of his eye watching Draco's handling of the vial. 'Would you mind?' he asked reaching out for it. 'This here, is a vial with a potion Draco just had,' he said. 'He drank that to protect himself, as have I as will granny Cissa. Would you drink one for me to keep yourself safe?' he asked. 'It would make me feel very much safer because even if I don't know you yet, we are family and family looks out for each other.'
