Julianna has a personality similar to that of a dog. If she likes you she will treat you great. If she doesn't like you to much be cautious. If Julianna hates you, well you better hope you can out run her. 
      In all seriousness she is very protective over those she cares about and if someone hurt them she will not hesitate to do the same to the other person (even if it is herself, more on that in backstory). Julianna wants to help others when something is wrong, she loves helping, but hates being helped. There is a short list of people she will really let in and those are her closest friends, and family.
