Sirius shrugged carelessly, "Might not have been me."
"You're the only one who goes anywhere near that stuff."
"Still doesn't prove anything," Sirius grinned.
"Yeah, but the detection charm does, especially since you never paid much attention to the class where we were taught how to mask our magical signatures…" Regulus said with a smirk.
"Mother doesn't actually use those charms, does she?" Sirius asked, suddenly looking worried.
"She may or may not," Regulus replied, intentionally making his answer as vague as Sirius's had been.
"Reg! I'm your older brother! You have to tell me! Please!"
Regulus shook his head, watching in amusement as his older brother panicked.
