In the third-season opener, the girls begin their senior year at Carlton, where Toby takes on a coaching position. Meanwhile, Kathryn befriends a tap dancer; Daphne starts her probation work at a free clinic; and Bay's new art teacher inspires her.

Daphne asks to take on more work at the clinic as she contemplates studying premed in college. Elsewhere, Bay tries to measure up to her art teacher's expectations while dealing with her injury; and Travis invites his girlfriend to a dance at school.
