Ehh, Mar has been on earth for quite a long time. Dodging hunters and other creatures. She really has no fear, which isn't a great thing. She'll just deal with it the normal way and move on. "Oh you're trying to be creepy? That's nice, byeeeeeeeeeeeeeeeeeeeeeeee"
Can just imagine Mar running into a vampire in a dark alley.
She see's him, He sees her and she spins around and walks the other way, yelling "NOPE!"
