40 Creepy Facts About The Black / Lestrange Family From Harry Potter
Bellatrix is Skilled at Occlumency
Bellatrix was an exceptionally gifted witch in many areas. One of the chief skills she never really got the chance to highlight, though, was her skill at occlumency. If you need a brief refresher on what exactly that is, it’s the ability to keep your mind from being invaded by other witches and wizards.
Although we never see her use occlumency in the books or the movies, she apparently taught Draco the skill in the books. As a result, Snape is unable to find out what he’s planning to take care of Dumbledore. If Snape had known that information, he likely would have passed it along to the Hogwarts headmaster.
