Harry Potter and the Methods of Rationality

'Very clever of you,' said Harry, still cold. 'But perhaps you mistake my interests.'

'Perhaps I do.' A hint of steel came into the silken voice. 'Indeed, that is precisely what I fear. You are playing strange games with my son, to a purpose I cannot guess. That is not a friendly act, and you cannot but expect me to be concerned!'

Lucius was leaning upon his cane with both hands now, and both those hands white, and his bodyguards had suddenly tensed.

Some instinct within Harry claimed that it would be a very bad idea to show his fear, to let Lucius see that he could be intimidated. They were in a public train station anyway -

'I find it interesting,' Harry said, putting steel into his own voice, 'that you think I could benefit from doing Draco harm. But it is irrelevant, Lucius. He is my friend, and I do not betray my friends.'

'What?' whispered Lucius. His face showed sheer shock.

Then -

'Company,' said one of the minions, and Harry thought, from the voice, that it must be the senior Crabbe.

Lucius straightened and turned, then let out a hiss of disapproval.

Neville was approaching, looking scared but determined, in tow behind a tall woman who didn't look scared at all.

'Madam Longbottom,' Lucius said icily.

'Mr. Malfoy,' returned the woman with equal ice. 'Are you being an annoyance to our Harry Potter?'

The bark of laughter that came from Lucius seemed strangely bitter. 'Oh, I rather think not. Come to protect him from me, have you?' The white-haired head shifted toward Neville. 'And this would be Mr. Potter's loyal lieutenant, the last scion of Longbottom, Neville, self-styled of Chaos. How strangely does the world turn. Sometimes I think it must all be mad.'

Harry had no idea at all what to say to that, and Neville looked confused, and frightened.

'I doubt it is the world that is mad,' said Madam Longbottom. Her voice took on a gloating tone. 'You seem in a poor mood, Mr. Malfoy. Did the speech of our dear Professor Quirrell cost you a few allies?'

'It was a clever enough slander of my abilities,' Lucius said coldly, 'though only effective upon the fools who believe that I was truly a Death Eater.'

'What?' blurted Neville.

'I was under the Imperius, young man,' said Lucius, now sounding tired. 'The Dark Lord could hardly have begun recruiting among pureblood families without the support of House Malfoy. I demurred, and he simply made sure of me. His own Death Eaters did not know it until afterward, hence the false Mark I bear; though since I did not truly consent, it does not bind me. Some of the Death Eaters still believe I was foremost among their number, and for the peace of this nation I let them believe it, to keep them controlled. But I was not such a fool as to support that ill-fated adventurer of my own choice -'

'Ignore him,' Madam Longbottom said, the instruction addressed to Harry as well as Neville. 'He must spend the rest of his life pretending, for fear of your testimony under Veritaseum.' Said with malicious satisfaction.

Lucius turned his back on her dismissively, and faced Harry again. 'Will you request this harridan to depart, Mr. Potter?'

'I think not,' said Harry in a dry voice. 'I prefer to deal with the part of House Malfoy that's my own age.'

There was a long pause, then. The grey eyes searched him.

'Of course...' said Lucius slowly. 'I do feel the fool now. This whole time you were just pretending to have no idea what we were talking about.'

Harry met the gaze, and said nothing.

Lucius raised his cane a few centimeters and struck it hard on the ground.

The world vanished in a pale haze, all sounds went quiet, there was nothing in the universe but Harry and Lucius Malfoy and the snake-headed cane.

'My son is my heart,' said the senior Malfoy, 'the last worthwhile thing I have left in this world, and this I say to you in a spirit of friendship: if he were to come to harm, I would give my life over to vengeance. But so long as my son does not come to harm, I wish you the best of luck in your endeavors. And as you have asked nothing more of me, I will ask nothing more of you.'

Then the pale haze vanished, showing an outraged Madam Longbottom being blocked from moving forward by the senior Crabbe; her wand was in her hand, now.

'How dare you!' she hissed.

Lucius's dark robes swirled around him, and his white hair, as he turned to the senior Goyle. 'We return to Malfoy Manor.'

There were three pops of Apparition, and they were gone.

A silence followed.

'Dear heavens,' said Madam Longbottom. 'What was that about?'

Harry shrugged helplessly. Then he looked at Neville.

There was sweat on Neville's forehead.

'Thank you very much, Neville,' said Harry. 'Your help was greatly appreciated, Neville. And now, Neville, I think you should sit down.'
