"You should know by now Potter that I am nothing but ridiculous," Regulus shot back easily, his tone almost teasing. He held a lot of bitterness towards James Potter, and yet frustratingly, with James stood in front of him he seemed to lose the bitter tinge to his feelings. He had to remind himself that James had made his choice, and he had turned his back on Regulus and it was that reason that they had not properly spoken in years. Still, it was nice to be reminded of when times were better, when the weight of the world on his shoulders had briefly been shared with James Potter's shoulders.
Smirking at James' words, Reg quirked an eyebrow in his direction as he continued piling vials into his basket. "That's a terrible shame. I hear there's a man with quite a stockpile of Jewelweed...you may have to grovel for it. There's probably some interest going to be added to the price as well...supply and demand, I'm sure you understand," Regulus said smoothly. He couldn't stop a short laugh at James' words, and he shook his head. "Oh, I'm sure you're positively drowning in fan mail. How many autographs do you send out a week?"
"It's what?" Regulus said haughtily, tilting his head slightly in question. A smug smile of victory tugged at his lips as James disappeared, and he returned to browsing in peace. Said peace was quickly broken by the reappearance of Potter, and Regulus sighed deeply. "Oh...that would be a shame wouldn't it. How desperately do you need it?" Regulus asked, stepping a little closer to James as he narrowed his eyes before he turned back to the shelf. A wave of pettiness washed over him, and he began placing all of the vials of Jewelweed into his basket. "I'm brewing a lot of potions at the moment, you see," he said, with an air of nonchalance. "Maybe I'll buy up Diagon Alley's stock of pyjamas too, and then I'll start owling you a pair of pyjamas every day until you can hardly move for pyjamas."
