Upon consideration, Olive offers to help Grace find the hummingbird with her birder expertise. She knows Grace, a self-proclaimed entrepreneur, recognizes business talk and drafts a formal proposal before rolling to PE class.

As the sixth-grade girls change for PE, First Maddie announces she has a list of the “hottest” girls in their grade. Although Olive doesn’t expect to have made the list, she feels insecure for the first time. As she examines herself in a mirror, comparing herself to First Maddie, she feels the mirror has become a “reversed-cursed mirror” that only shows flaws. She again promises herself to find the hummingbird and wish for “normal” bones. Grace approaches Olive to talk.

Olive and Grace bond during PE; Olive can’t participate because of her OI, and neither can Grace because of her asthma. Olive is surprised to see that Hatch doesn’t participate in PE either; he’s on the bleachers reading his comic, with a sloth (a “therapy animal”) clinging to his neck. Olive and Grace bond over their shared love of snacks and Judy Blume books, and name themselves the BlumeBird Society. They decide to look through past yearbooks to investigate previous wish-makers.
