When Bertha Jorkins took work to her boss's home, she saw too much.66 Yet, it wasn't because she was too lazy that Barty Crouch Snr. placed a memory charm on her, much as it wasn't lust which impelled her many years earlier to follow a fellow student to tease him about kissing Florence.67 Bertha Jorkins was known as someone who was too nosy, too inclined to gossip, and when she was overdue to return from an Albanian holiday, her current boss, Ludo Bagman, really ought to have been more concerned that someone like her, the sort of person who annoyed people by excessive prying, had gone missing.68 Once she left her aunt's Albanian home, Bertha would meet Wormtail at a wayside inn, and a revived Voldemort, waiting to make her into his last Horcrux, the Horcrux of Gluttony.

Does Nagini, like Harry, get headaches from Voldemort's continual proximity? And can this pet snake, who provides Voldemort with so much comfort and nourishment, and whose venom enabled Voldemort to regain a body, make truly independent decisions, like Harry? Voldemort is known to possess Nagini when he wants to penetrate the Ministry of Magic, and she can act as sentinel at Bathilda's place or summon Voldemort when necessary.

Once Crouch's memory charm was broken, Bertha Jorkins simply knew too much. Wormtail, who had fled justice for the murder of the Potters, had thoughtfully brought along Voldemort's own wand, as well as persuading Bertha to accompany him on a night stroll to meet the newly created Babymort. Voldemort, weakened by his long stint as "less than the meanest ghost' 69 insists on making one more Horcrux. And unlike with Harry, Voldemort did say the spell when he killed Bertha Jorkins to make Nagini a Horcrux. When Voldemort fell at Godric's Hollow, he had split his soul into six parts, and Nagini is to be the seventh to reach his goal. But Voldemort never knew about the Harrycrux. Thus, the Naginicrux becomes his eighth soul part, one Horcrux too many. And when Jo remarked how nauseous her editor found the process of creating the rudimentary body that formed Babymort on Leaky's own Pottercast 130,70 no wonder the Naginicrux is almost a synonym for overkill ’ Voldemort is showing a lamentable gluttony of soul parts.

Nagini does represent animal nature. Often Voldemort threatens to feed Wormtail or other victims to her for dinner. Even large snakes cannot swallow adult humans whole, but the gluttonous symbolism persists. All the more so as Neville, her eventual executioner, abstaining from the Carrows' pureblood madness, has hidden in the Room of Requirement, leading the resistance and collecting victuals from Aberforth Dumbledore's Hog's Head Inn. But Nagini, the useful tool of Voldemort, symbolises far more than gluttony, and its related issues of control and injustice. When Neville beheads her, after extracting Gryffindor's Sword of Justice from the Sorting Hat, he is also eradicating the sort of poisonous bigotry which has been allowed to proliferate unchecked in Slytherin house, destroying the lives of so many, not to mention relieving the cruelty inflicted on this unfortunate creature.
