Special powers? You mean...like being much stronger than they look? Knowing things they shouldn't? [There has always been talk about such people, and after becoming an Exorcist--even more so after coming to Marina--Miranda has learned not to discount anything.]
I think...I-I can understand why someone might be afraid of what they don't understand. [Miranda was like that--can still be.] But if they're not trying to hurt anyone, then they're just like everyone else.
