The Polyjuice Potion Plan

Determined to prove that Draco Malfoy is the Heir of Slytherin, Hermione devises a plan to use Polyjuice Potion to transform into Slytherin students and interrogate him. She, Harry, and Ron steal the necessary ingredients from Snape's private stores, causing a diversion in Potions class. They brew the potion in Moaning Myrtle's bathroom, a secret and safe location. The plan is risky and requires them to obtain hairs from their targets: Crabbe, Goyle, and Millicent Bulstrode. The potion takes a month to prepare, and the trio waits anxiously for it to be ready, hoping to finally uncover the truth behind the attacks.
