"My hero," she teased, offering Severus a mischievous grin. She liked getting a rise out of him, but only under the correct circumstances. Earlier that evening was certainly not the way she wanted things to go. But sooner or later she liked to think that she and Severus would patch things up. Maybe he would realize that she really had his best interests at heart, even if she hadn't gone about it in the best way.
She wanted to argue that she could take care of herself, but since it wasn't Severus himself but this fear demon thing, she doubted it would put his mind at ease. So instead she kept her mouth shut and simply walked alongside him.
