Katie, Jessica and Daphne were filming at the beach yesterday. It's obviously from the same episode they were filming earlier in September.
Guess: Jessica and Katie filmed all the scenes that were just Riley and Ella back then, and they came back to film scenes that Daphne was involved in, since she probably wasn't available for them originally. More spoilers and set photos were posted yesterday on homepage so check them out!
