The corsage Amma gives Ethan has a surprise: a small graveyard bone tucked inside. "A little protection never hurt anybody" (12.13.13).
Lena is decked out in a gorgeous black-and-silver ensemble. It's a little classier than Link's get-up: a t-shirt with a tuxedo design on it. Cute, Link.
Link has brought a date: Lena's persuasive cousin, Ridley, wearing the skimpiest dress a Jackson High formal has ever seen.
Ethan tries to convince Link that Ridley is bad news, but he won't listen.
At the formal, Ethan and Lena get their photograph taken and share a passionate kiss. Unfortunately, someone has decided to prank her. When the flash goes off, a bucket of wet soap flakes dumps onto Lena's head, ruining her hair and her dress.
Things get pretty tense for a while. Ethan even punches someone in the face. Yikes.
Lena and Ethan just want to leave, but Ridley decides to defend her cousin.
Chaos ensues: ripping dresses, blowing light fixtures, setting off the sprinklers, and shorting electric equipment. Ridley almost takes down the whole stage where the Ice Queen is being crowned.
Back at Ravenwood, Macon grounds Lena for not leaving as soon as she saw Ridley.
Lena, though, wants to know how exactly Macon even knew she was there.
Macon confesses that Boo Radley, the dog, is—wait for it—his spy. Macon can see through Boo's eyes. This sure gives new meaning to the term seeing-eye dog.
