Harry Potter and the Methods of Rationality

'Well?' said the Potions Master.

'All right,' Harry said slowly. It was hard to see how having a conversation and being unable to tell anyone could be more constraining than not having it, in which case you also couldn't tell anyone the contents. 'I promise.'

Severus was watching Harry intently. 'You said once in the Headmaster's office that you would not tolerate bullying or abuse. And so I wonder, Harry Potter. Just how much do you resemble your father?'

'Unless we're talking about Michael Verres-Evans,' Harry said, 'the answer is that I know very little about James Potter.'

Severus nodded, as though to himself. 'There is a fifth-year Slytherin. A boy named Lesath Lestrange. He is being bullied by Gryffindors. I am... constrained, in my ability to deal with such situations. You could help him, perhaps. If you wished. I am not asking you for a favor, and will not owe you one. It is simply an opportunity to do as you will.'

Harry stared at Severus, thinking.

'Wondering if it's a trap?' said Severus, a faint smile crossing his lips. 'It is not. It is a test. Call it curiosity on my part. But Lesath's troubles are real, as are my own difficulties in intervening.'

That was the trouble with other people knowing you were a good guy. Even if you knew they knew, you still couldn't ignore the bait.

And if his father had protected students from bullies too... it didn't matter if Harry knew why Severus had told him. It still made him feel warm inside, and proud, and made it impossible to walk away.

'Fine,' Harry said. 'Tell me about Lesath. Why is he being bullied?'

Severus's face lost the faint smile. 'You think there are reasons, Potter?'

'Perhaps not,' Harry said quietly. 'But the thought had occurred to me that he might have pushed some unimportant mudblood girl down the stairs.'

'Lesath Lestrange,' Severus said, his voice now cold, 'is the son of Bellatrix Black, the most fanatic and evil servant of the Dark Lord. Lesath is the acknowledged bastard of Rabastan Lestrange. Shortly after the Dark Lord's death, Bellatrix and Rabastan and Rabastan's brother Rodolphus were captured while torturing Alice and Frank Longbottom. All three are in Azkaban for life. The Longbottoms were driven insane by repeated Cruciatus and remain in St. Mungo's incurable ward. Is any of that a good reason to bully him, Potter?'

'It is no reason at all,' Harry said, still quietly. 'And Lesath himself has done no wrong that you know?'

The faint smile crossed Severus's lips again. 'He is no more a saint than anyone else. But he has pushed no mudblood girls down the stairs, not that I ever heard.'

'Or saw in his mind,' said Harry.

Severus's expression was chill. 'I did not invade his privacy, Potter. I looked within the Gryffindors, rather. He is simply a convenient target for their little satisfactions.'

A cold wash of anger ran down Harry's spine, and he had to remind himself that Severus might not be a trustworthy source of information.

'And you think,' Harry said, 'that an intervention by Harry Potter, the Boy-Who-Lived, might prove effective.'

'Indeed,' said Severus Snape, and told Harry when and where the Gryffindors were planning their next little game.

There is a main hallway running through the middle of Hogwarts's second floor on the north-south axis, and near the center of this hallway there is an opening into a short corridor which goes a dozen paces back before turning at a right angle, making an L-shape, and then goes a dozen paces more before it ends at a bright, wide window, looking out from three stories above upon the light drizzle falling over the east grounds of Hogwarts. Standing by the window you can hear nothing of the main hallway, and no one in the hallway would hear what went on by the window. If you think there is anything odd about this, you haven't been in Hogwarts very long.

Four boys in red-trimmed robes are laughing, and a boy in green-trimmed robes is screaming and grabbing frantically onto the edges of the opened window with his hands, as the four boys make as though to push him out. It's just a joke, of course, and besides, a fall from that height wouldn't kill a wizard. All good fun. If you think there is anything odd about this -

'What are you doing?' says a sixth boy's voice.

The four boys in red-trimmed robes spin around with sudden starts, and the boy in green-trimmed robes frantically pushes himself away from the window and falls to the floor, face streaked with tears.

'Oh,' says the most handsome of the boys in red-trimmed robes, sounding relieved, 'it's you. Hey, Lessy, you know who this is?'

There isn't any answer from the boy on the floor, who's trying to get his sniffling under control, and the boy in the red-trimmed robes draws back his leg for a kick -

'Stop it!' shouts the sixth boy.

The boy in the red-trimmed robes wobbles as he aborts the kick. 'Um,' he says, 'do you know who this is?'

The sixth boy's breathing sounds strange. 'Lesath Lestrange,' he says, his breath coming in short pants, 'and he didn't do anything to my parents, he was five years old.'

Neville Longbottom stared at the four huge fifth-year bullies in front of him, trying very hard to control his trembling.

He should have just told Harry Potter no.

'Why are you defending him?' said the handsome one, slowly, sounding puzzled with the first hints of offense. 'He's a Slytherin. And a Lestrange.'
