Lizzie's character?

Lizzy is Gar's aunt, a sister of his mother's. She is described as "a small, energetic woman, heavily made-up, impulsive." Her actions show her erratic emotions that sometimes overwhelm her. Her speech is blunt, and she shows a lot of affection towards Gar due to the fact that she cannot have children but longs for a child's presence to fill her home. She is the reason that Gar is going to Philadelphia in the first place, and Gar has mixed feelings about living under her roof and having her act as his surrogate mother.
