She doesn't have a heartbeat, a soul. But she's fast, blood thirsty, and looking for her next meal. Unfortunately for Gracie that "meal" just so happens to be her. Or is it? Aly thinks all this person is - is their next meal, but Gracie shows them that there is more to life than "kill or be killed". For someone without a heartbeat, Gracie doesn't fail to make their heart flutter.
