Regulus almost choked at the idea of an inner circle of any type. "I never meant that he'd want me in his inner circle. I think I might need a shower now."
He thought for a moment, but the decision was easy. He wasn't a bystander and wouldn't be able to be one, not with Bella out there wanting him involved, not with Sirius and Remus and James. He also knew what happened to supporters that weren't trusted. They died and quickly. "I want your word that Remus will be included in this sanctum sanctorum you have. He gets the same protection as anyone else in there. You give me that, and I will help. I won't join, but I'll help." He would have done it anyway.
