Dire situations are what Aradia's used to, so she'll be flourishing (a little scarily) in this situation. She'll be doing anything she can to help out, especially where the raptors are most concentrated.
Fear, however, isn't something she's used to, and will most likely react pretty terribly and might interfere with what she's doing. She'll try and push through it to find the source of things, but when it comes to very deep emotion, she's not 100% stable. She won't be violent towards other people unless provoked/seeing them differently/etc, though any interactions with her are likely to be...interesting if she's under the influence of the fear effect.
