Lonan made it through DADA without vomiting all over his books, but the professor recognized that he was hungover, so she called on him all class. It was a valid strategy for her to make an example of him to the rest of the class about the perils of drinking before class, but Lonan was able to answer all of the questions after she asked him three or four times. When he told his friends that he could probably do that shit in his sleep, he really wasn't kidding. It was a shame that Lonan didn't have the dedication to be an Auror, because he definitely had the intelligence. Even his brothers admitted that Lonan could pull it off if he wanted.
He struggled through potions, but Slughorn had come through and gave him a hangover potion when Lonan pretended to care what Slughorn had done during the summer. He let his mind wander for most of it, making note of the fact that Slughorn had invited him to another one of those God awful parties. He hated how Slughorn made him feel like pea plant in Mendel's garden, but the food was good and Slughorn never made too big of a fuss when Lonan started drinking booze so he would go.
The rest of his day went by pretty smoothly, but now he was going to be late for Care of Magical Creatures because Professor Weasley had kept him after class. He wasn't in trouble, but Professor Weasley never could resist the opportunity to talk with Lonan about muggle rock music. It fascinated him. You'd think Lonan was giving instructions on how to mass produce Philosopher's Stones, the way he sat at the edge of his seat, eyes as wide as a child seeing someone fly on a broomstick for the first time. Last year Lonan had given Professor Weasley his Deep Purple albums to listen to, which had gone over phenomenally. The Professor looked like he was ready to cry when Lonan explained that the band no longer toured, or even existed.
The Professor had heard Black Sabbath while in London over the summer, and asked Lonan if he had any records he could loan him, which caused Lonan to laugh so hard that he almost passed out. He promised that he would have his brother mail him all the records, deciding to explain to cross the Ozzy/Dio bridge when the time came, and headed out to the grounds.
He hated Care of Magical Creatures. He didn't care how to take care of whatever rare, stupid creature Loony Lovegood was going to pull out for them to see. The proper way to take care of a firecrab was not something Lonan could even pretend to give a flying fuck about, but Lovegood never seemed to notice Lonan not paying attention. Or she never said anything if she ever did. Hector and Zelda had both taken Divination, and had told Lonan to try and switch so they could at least suffer together, but Lonan would take being outside to whatever the sickly sweet perfume the Divinations teacher sprayed around the room. He had been up in the tower once and had only made it five minutes before he felt like he was going to hack his lungs out, which was only an experience he enjoyed when he was smoking really, really good weed.
He could see Lovegood was already in front of the students talking to them, but he figured she probably wouldn't even notice that he had been late. And if she did, he would tell her to speak with Professor Weasley about it, who was probably still giddy at the thought of listening to more Black Sabbath.
