There are a few here who're about as stoic then--Raven can be, but then that's part of her story and she has to be, or bad things happen. She could likely calm Holiday down whether she wanted to be calmed or not, but Raven tries to not be that intrusive without damn good reason or need. Ah, the ethics of powers like Empathy...

"Some of it is superstition, and some of it is because when they did bring an army over here, to try and get rid of us, we decided our best strategy was to scare them. Badly. Yes, we're really in no better place than they are, so to speak--but it's hard enough without fighting them too. We succeeded rather well, and truth to tell--there are those of us here who ARE scary. Who you should be rightly cautious and afraid of."

Although perhaps not for the reasons Holiday will think--still.
