Remus and Danny McKinnon undertake their first dangerous mission to infiltrate werewolf gatherings at the Manticore's Head pub in Knockturn Alley. Despite Remus's attempts to lead diplomatically, tensions escalate when Gaius uses legilimency and dark magic against him, forcing Remus to retaliate with unexpected magical power. The mission ends in conflict rather than successful intelligence gathering, leaving Danny traumatized and Remus questioning his role in the war. Moody's cryptic approval suggests this violent confrontation was somehow part of a larger plan.
