One Secret Life of the American Teenager couple just made a MAJOR commitment!

In the summer finale “And Cirumstance,” Amy (Shailene Woodley) starts to unravel Ricky’s (Daren Kagasoff) proposal plans, but no one will give her any information. In the meantime, Ricky grows increasingly nervous about preparing his valedictorian speech, which is full of heartache as well as surprises.

Once graduation has commenced, the Grant High students embark on what is to be the night of their lives. Just as the party is in full swing, Grace (Megan Park) is stunned to see Daniel’s ex-girlfriend, while Lauren (Camille Winbush) refuses to hook up with Jesse. In the end, two unannounced visitors arrive, delivering one final wish for Adrian (Francia Raisa).
