Talk:The Rhythmic Runes

There's a thing i don't understand. Why does it say Harry Potter and the Half-Blood Prince (film) in the "Appearances"-section while it says Harry Potter and the Deathly Hallows: Part 2 DVD2 (Warner Bros. Studio Tour London) in the "Notes and references"section"? --Danniesen 07:16, May 24, 2012 (Denmark)
