Now, it's definitely true that a whole bunch of Slytherin sat out the Battle of Hogwarts. (I probably would have stayed home with a bottle of wine and some Netflix too, but what can you do.) However, does this necessarily mean that they're incapable of being brave? Not so much, according to Granger.

"Narcissa Malfoy saved the day in that grotto in the Forbidden Forest... she has her moment where she’s punished by the Dark Lord, and sent up there to do a quick check to see if Harry Potter is dead," Granger explained. "She finds out that he’s alive; she gets the answer that she wants. Now her son is alive, and she doesn’t reveal that Harry Potter is alive. It could conceivably cost her her life but courageously, she says, 'I’m going to let this boy live.' She’s the archetypal Slytherin woman... but that’s a very courageous act that saves Harry from being murdered on the spot."

Acting in one's -- or one's family's -- own self-interest is definitely not the same type of bravery that defines a Gryffindor, but the actions of a Narcissa Malfoy should not be forgotten when you look at the bigger picture. And like, I'm sorry, but if you were put in Slytherin house, would you want to fight Harry Potter's battles for him? Seems like a pretty thankless job, if we're being honest.

"When people start talking about Slytherin, they try to overlook the instances where, in their self-interest, they act heroically," Granger continued. "[Narcissa] is a lot like Lily Potter... she’s able to stand up to the Dark Lord. It’s very staggering in the books. Even Narcissa Malfoy, in her love for her son, is going to protect Harry Potter in front of the Dark Lord. If [Slytherin] are really all bad, Harry dies there right on the spot."

In other words, bravery has different meanings for different people, folks. MOVING ON.
