Isabelle Cross's Links
Michael is Izzy’s older brother. She admires him a lot, and when she was younger wanted to be like him. Now that they’re older, Michael’s occasional recklessness and refusal to spare any thought for himself cause her a lot of stress and frustration. Still, she loves him and would do anything for him.
Izzy is Michael’s younger sister. Though they were close when they were younger, they have drifted apart a bit. This is intentional on Michael’s part, as he has secrets he doesn’t want her to learn and doesn’t want to burden her or their mother. Though one would expect an older brother to be protective of his little sister, it’s really the other way around— since Michael spent a long while bedridden as a child after a near-fatal incident, Izzy considers herself responsible for protecting Michael. Despite the complications, Michael dearly loves his sister.
The first time Izzy meets Andrew, she literally assaults and threatens to kill him if he somehow causes her brother any pain. She later apologizes for her behavior and eventually grows to see Andrew as a friend. After Andrew decides to stay in the world of the living with Michael, she starts referring to him as her brother-in-law and considers him part of the family.
Andrew was somewhat frightened by Izzy when he first met her, but he felt that he understood her anyway. and that she was likely only doing what she felt she had to do to protect her brother. He eventually admires her quite a bit and is impressed by her emotional fortitude. They develop a friendship full of teasing. After he decides to stay with Michael, he’s flustered by her decision to refer to him as her brother-in-law, but welcomes it and returns the favor whenever possible.
