Lucius Malfoy is a liar. An ex-Death Eater, an ex-Slytherin, a womaniser and a liar. A liar whom Hermione Granger found herself in bed with after months of boredom with Ron, weeks of too little happening in her life, and a single night wherein she, against her better judgement, consumed far more firewhisky than could be considered healthy.
A night turned into a week, a week into a month, a month into a year and it is still going on. She knows very well that Lucius Malfoy is a liar, yet she can't seem to break away from his grasp: or maybe she just doesn't want to.
She found out a long time ago that Lucius' wife knows and doesn't care; apparently affairs of this kind are commonplace to the point of being expected. Purebloods still work differently to the rest of society after all.
She feels guilty when she realises this. Ron still doesn't know. Ron will never know. Ron may be a pureblood but he doesn't work with the same sort of old traditions as people like Lucius Malfoy. There would be a scandal if they were ever found out, and neither of them can afford such a thing. It is better to carry on lying, Lucius says; that way no one gets hurt.
Lucius Malfoy is a liar. An ex-Death Eater, an ex-Slytherin, a womaniser and a liar. But, as he so often reminds her, Slytherins are meant to lie: they are expected to; it's in their blood, so that means he is doing nothing wrong.
Hermione Granger does not think herself to be a liar. She is an ex-member of the Order of the Phoenix, an ex-Gryffindor, a hard working member of society and above all an honest person. Sometimes, however, Lucius will remind her that she is a liar, perhaps an even worse one than he is. She is a Gryffindor after all, and Gryffindors don't lie.
