He and James went into immediate action.
"Expelliarmus!" James shouted, quickly pocketing Sirius's wand as it flew into his
hand.
When Sirius turned his rage on his friends for interrupting what looked to be less
like an interrogation and more like a demonstration, Remus took over, using his werewolf
