George sighed. "Alex, you might not have consciously gone off to get drunk, but whoever this Andrew is, he must have regular rounds if he's selling contraband." And don't think he wasn't going to be informing the Headmaster of this Andrew, regardless of the fact that he and Fred had done very similar things while at Hogwarts. "So even if you didn't know you would end up there, you knew. And you also made a conscious decision to buy the alcohol, instead of turning around and going back to the Great Hall. So you don't get to blame this on happenstance or other people. It's all you, kid."
He rubbed Alex's back and sighed into his--very black--hair. "You're right, you screwed that up. But it's a privilege you could earn back. Professor Black thinks highly of you Alex." And that might be pushing it, a lot, but Regulus had called Alex bright, and he got the feeling he didn't give that praise to a lot of people.
"And for the record, I'm pretty sure the Headmaster thinks everyone is a whiny fuck," he said, trying to lighten the mood just a little. "Well now you have, and as the world ended? Losing points is something nearly every Hogwarts student does. Even your Aunt Hermione lost points."
He held on to his son tightly, like he hadn't since Alex had been a tiny kid he didn't really understand. "I love you Alex, and so does your mother. But unlike your mother, I know what you're going through. And talking to someone will help. Maybe especially if that someone isn't a parent or another Weasley. And if you don't like Doctor Brocklehurst, we'll find someone else."
