Senior Night is upon William Penn Academy, and Beverly soon discovers she is missing out on the ceremonial adoration presented to mothers with athletic children.  Much to Adam’s embarrassment, Beverly pushes for her moment to shine with a kiss and a rose and encourages Principal Ball to establish a Non-Athlete Senior Night.  As Adam attempts to foil his mother’s plans, Erica finds herself lacking any interested friends to appoint “pre-wedding fun captain.” Reluctantly she engages her eager “sister-in-law to be” Joanna, who inadvertently doesn’t meet expectations but ultimately proves herself worthy of being called sister.
