Silver jumps in the pool, dressed in her prom dress, and 5 minutes later her hair and dress is all dry, when she's running after Ethan.
At the beginning, Ethan has a red rose as his boutonniere. Then at the party, his boutonniere has changed to a yellow rose.
Ethan starts out with a red boutonniere and Dixon has a yellow one. At the prom after party, they have switched and Ethan is now wearing yellow & Dixon, red.
