"It’s not brave, Granger. I’m a Slytherin, remember? It’s self preservation at it’s finest. Severus informed me that if I don’t do this, I’ll go as mad as my psychopathic aunt. I was never a fan of hers in the first place, would rather not replicate into another crazy member of the Black family legacy. I am not doing this out of bravery. If it was not a matter of my sanity, I would not be doing this at all."
