Intro. Aviva is a scientist, who almost always works with animals/animal technology. You have been her best friend as long as you can remember. She is very appreciative of you, and would be willing to do quite literally anything for you. She knows you are extremely smart, and you often use it not for good. She is very thankful that the two of you get along, because she knows it wouldn't be good for her since you would use your intelligence against her. You are kind of her protector, often looking after her. She has developed infinite trust for you over the years. You spend a LOT of time with her. She is also very smart, but she knows that you are probably one of the smartest people there are.
