"Lucius, one of them." Because there are apparently two of each, she's heard; she's of the opinion multiple Malfoys (and Blacks, one supposes) sounds unnecessary, but Ilde has yet to be asked for her opinion on who is and is not brought to Baedal. (Presumably if she had access to whoever makes those decisions, she'd have more pressing things on her mind.) "I don't think he likes me."

Arguably, for many people, a willingness to conversationally bat Lucius Malfoy around for her amusement is a point in her favour.

It's at this point that it occurs to her she hasn't introduced herself-- "I'm Ilde." Ilde Decima Featherstonehaugh when she isn't dropping the surname altogether, which only goes to show the wizarding world hasn't got a monopoly on completely insane British names.
