Issy is a very people focused individual, living in a world of people possibilities and has, for the most part, very good people skills. She is someone who has a lot of time for people, often going out of her way to help someone in anyway that she finds possible. This aspect of her personality lends itself in part to her career as a Healer, though can be hazardous to her personal life. As she has aged, Issy has learnt to be a little more selfish with her time and resources but not too the point where he counterbalances this aspect.
As with people she has more than just the one shining aspect to her personality; for she may go out of her way to help people, she may be considered people focus and perhaps, at times, kind. There is also the aspect of her that is sassy and sharp, the side of her that tells the blunt honest truth, isn’t afraid to take responsibility for her actions and tends to be open an honest about the decisions she has made with her life.
As someone who was raised within a extreme pure blood environment she does have some underlying judgemental attitudes and feelings. These feelings however are switched from what someone would assume such as muggle born and half breeds too pure bloods themselves and more importantly,the ideals espoused by those sort of people.
She is an out and proud blood traitor and an loud voice in the idea of reforming that underlying culture within the wizarding world.
All this aside, Issy is not above using certain situations to her own advantage. The best example of this is that she stayed within the circle of her family and their ideals until she had graduated University so that she was able achieve the best education possible without the financial and emotional struggles that come with stepping out from such a family.
