Alecto had been thrown out by her brother, who was irritable and had a face like a pug that had swallowed a lemon. Scabior had been browbeaten into accepting it as his duty to provide her with a place to stay.
"Please, Scab, you're my best friend—It'll just be for a couple of nights and then I'll be out of your hair, I swear."
He hadn't minded letting her stay. He'd thought it would be fun, sitting up 'til all hours, eating Chocolate Frogs and listening to the wireless. He had quite enjoyed it at first – they had the same taste in rock bands, and wine, too, and bizarre Bertie Bott's flavours. Unfortunately, they also had the same taste in good-for-nothing men.
Greyback had taken to coming over every night since he'd found out Alecto was staying. It was bad enough that Scabior had to listen to her going on about him during the daytime.
"He's so strong, and his voice—It does things to me, Scabior. He says he thinks I'm special."
"'E prob'ly wants to make you into a werewolf."
"Oh, don't be silly," she'd said, and then giggled in a girlish sort of way that had made him want to be sick into his cornflakes. He knew Greyback was only doing it to infuriate him. Greyback didn't think anyone was special. Greyback would shag anything physically tangible.
Mornings weren't the worst, though. In the evenings, he'd hear them upstairs. Breathing. Laughing. Bedsprings squeaking. It made concentration quite difficult.
He took a shower to try and drown them out. They must have stopped while he was in, though – Greyback was an utter troll – because when he came out, it was silent, and he smirked to himself, but then they started up again.
Bundling his trousers under one arm and holding his towel about his waist with his other, Scabior marched across the hall. He had had enough.
"Scabior!" cried Alecto, as he flung her door open, and she tried self-consciously to button up the top of her blouse. Scabior raised a disapproving eyebrow. Greyback smirked at him. He was slouching with his legs spread apart, Alecto perched between them.
"Well, I'm glad to see you're wearin' trousers, at any rate."
"Can't say the same for you," said Greyback with mild amusement.
"Leave it out, yeah? D'you two think you could not do this while I'm about?"
Alecto looked embarrassed. Greyback guffawed. "What, because you're jealous?"
"I am not jealous," hissed Scabior. "She is my best friend. I am tryin' to listen to the wireless. So, if you don't mind, could you just play Gobstones or somethin'?" He turned to leave.
"The wireless? God, the youth these days. Where's your sense of fun? And in any case," growled Greyback, and Scabior turned to look at him, "I wasn't suggesting it was me you were jealous of."
Scabior narrowed his eyes. "You are an utter twat. Goodbye."
"You can come and join us if the wireless gets too dull," Greyback called after him as the door slammed.
