For the next month, she set up camp at Hogwarts, spending her days going to classes and her nights wandering the castle and trying to come up with new spells. The nights were awful with nearly nothing to do.

She couldn’t even bring herself to feel bad that their drama and unhappiness was her entertainment. Eternal solitude didn’t lend itself to having morals.
