The Perils of Potion Making

Tasked with improving Amortentia for Professor Slughorn, Hermione Granger uses the principles of Polyjuice Potion to link the draught to a specific person using a strand of their hair. Conscientious as ever, she insists on testing the brew on herself first. To avoid any awkwardness, she selects a hair from Viktor Krum, knowing he is safely away in Bulgaria. But the moment she takes the first sip, Hermione realises to her horror that it wasn't Viktor's hair at all.
