I believe I do have a timeline of events that you might find informative.
Vanessa is speaking to members of her new sewing circle. They offer her their condolences on the death of her mother.
It transpires that there is some confusion in the group about the identity of Vanessa’s mother.
Vanessa tells them that her mother was Susanna Noone, who had died three years previous from a long illness.
Vanessa explains that Aunt Gally, as she calls her, was her mother’s companion. She tells them that, although Gally was like a second mother to her, they were not related.
The group are surprised to learn this, given Vanessa’s resemblance to Gally.
