She seems to have a close relationship with her daughter, and this could be due to the divorce, which made her Iris' main caretaker.
Iris seems to have a lot in common with her mother, and this can be seen in the carefree and somewhat air-headed nature the two share. Isabelle is caring and holds her daughter in high esteem.
