The terrible acting was on purpose because Julie knew about the app and then she had to fake having a heart attack. So basically, an actor who acts as a profession, had to act like they were a novice/bad actor. But I agree about letting Gabi stand there with the phone, although since Julie knew what was up, I could see letting it play out. How else would Gabi have been proven guilty in front of everyone. That said, Lani could have done this at her wedding and saved us all from having to see this fiasco.
