Summary: Rosewood is a perfect little town. So quiet and pristine, you'd never guess it holds so many secrets. Some of the ugliest ones belong to the prettiest girls in town -- Aria, Spencer, Hanna and Emily, four estranged friends whose darkest secrets are about to unravel.
Aria Montgomery: Aria: I hope so too.
Department Store Clerk: Salesboy: I'll have to put some of these back.
Hanna Marin: Hanna: But they're all maybes.
- Goof (miscellaneous): Toby is listed as Toby Marshall in the credits.
- Goof (factual errors): The movers carry a chair into Maya's new home, passing the Elmhurst Real Estate "SOLD" sign. The phone number on the sign is "1-800-HOUSES", which is 1 letter/number too short to be an actual phone number.
