Gillian

Gillian is a character on Splitting Adam. She is Adam Baker's younger sister and she is portrayed by both Tate Chapman and Abby Chapman.

Personality
Gillian is Adam's mischievous, hashtag obsessed little sister. Karate and ballet are among her many talents, and that means two extra stops on Adam's list of drop-offs. She might give Adam a heavy dose of teasing, but deep down, she loves her big bro. And that's good, because she's about to get a few extra doses of him!
