About two weeks later, the effect of the pills eventually wore off but despite of this, Mikey never returned to Frankie. Rather than be sad that her old friend was gone for good, Frankie decided to make new friends to keep her company her new mansion. Soon, the friends we know and love began to spring up: Bloo, Wilt, Coco, Edwardo, Mr Harriman, and many, many more.
But what about Mac and Madam Foster?
Mac was a depiction of Frankie's possible younger brother.
Around 1933, when Frankie was 7, Mrs. Foster was expecting her second child. Frankie's parents wanted to try to have another child in hopes that they could have a "normal" child. The entire Foster family was thrilled to have another child, including Frankie. But, by the time the baby was due, something went horribly wrong: during childbirth, the umbilical cord had gotten wrapped around the baby's neck like a noose and it was suffocated to death. Despite the baby dying, the family gave him a name: Mac. And because of this incident, Mac was an image on what Frankie's younger brother would have been like if he had lived.
Madam Foster was based off Frankie's actual Grandmother. She acted almost exactly like Madam Foster, sweet, funny and a bit odd. Frankie's Grandmother loved Frankie dearly, even if she was mentally handicapped. She often made cookies and sweets for Frankie, or little toys. But in 1936, when Frankie was 9, her grandmother was diagnosed with terminal brain cancer. She died 6 months later.
