A/N — I'm pretty sure I'm high right now, because I'm absolutely mesmerised by the white Bertie Bott's Bean.
"What flavour do you think this is?" Regulus asked, holding up the white Bertie Bott's Bean.
"I don't know," Barty said, rolling his head slowly to look at Regulus. "That's kind of the point of them." Regulus stretched his arm across the space between them.
"Can you lick it?"
"What? Why would I do that?" Barty asked, pushing himself up into a sitting position. He knocked the bag, a few beans escaping and sliding down the roof.
"Because I don't want it if it tastes bad," Regulus said, bringing it closer to his face. "It's completely white. Do you think that's good?" he asked. "Or very bad?"
Barty lay back down, content to let Regulus come to a decision on his own. The bean appeared in front of his face again.
"What is wrong with you?" Barty asked, pushing Regulus' hand away. "Lick your own damn bean."
"But—" Regulus pushed himself up onto his knees, sliding down the roof a little before he managed to catch himself, the bean still firmly grasped between his thumb and index finger. "—what if it's bad?"
"Then why would I want to lick it for you?" Barty asked.
"Because I don't want to," Regulus said. Barty looked unimpressed. "And that's what friends are for."
"Licking each others' beans?" Barty asked sceptically. Regulus paused for a moment, thinking.
"Well… yeah," he said, nodding. "I'd do it for you." Barty pulled an orange bean from the bag.
"You'd lick this?" he asked.
"Of course."
"But I don't want you to," Barty said.
"That's not the point," Regulus tried to reason. "It's the fact that I would do it that counts."
"Why would— Just eat your bean," Barty snapped, putting his own bean in his mouth. Regulus shrugged and did the same.
"Oh, it's nice," Regulus said cheerfully. Barty's face screwed up in disgust and he spat his be an out, gagging.
"That was the most vile thing I've ever tasted," he groaned.
"Should have let me lick it," Regulus said. Barty glared, and reached for a handful of beans, throwing them at Regulus. Regulus ducked. "I did offer," he muttered sullenly. Barty picked up a green bean.
"Lick this," he said, holding the bean out to Regulus.
