Family

Galinda had always wanted a sister. They would tell each other secrets, do each other's hair and make-up, and stay up late talking and laughing. She'd be able to confess her fears, and anything else she'd always been too hesitant about disclosing with the (admittedly shallow) friends she'd made at school.

Elphaba didn't fit the mold, in more ways than one. Galinda had to pry to get her to share, she found no joy in accessorizing, and her smirks far outnumbered her laughs.

Despite it all (or perhaps because of it), Galinda regarded Elphaba as the sister she never had.
