Voldemort Kills Snape

A major spoiler for the final Harry Potter book. Someone managed to get Harry Potter and the Deathly Hallows early, and scanned every single page of it. A complete spoiler list was uploaded to Ebaumsworld, and from there people dressed up as Nigras and spoiled the entire series ending for fans.

This event was almost exactly like the "Snape kills Dumbledore" phenomenon.
