Bernice's mom talks about a tattoo on Benny's hiny, but there's no way she has seen it (if it was there).
When Bernice is in bed with Benny, she has full face makeup, but when her mother enters the room, Bernice has minimal makeup on.
When Benny is reading Claudio and Hayley's chat on Claudio's phone, you can see that there is no network or WiFi signal. There was no time for Claudio to put the phone on flight mode before sliding it under the table.
The scene where Bernice is talking to Hayley on the deck looks like it is shot with a green screen and then the background is added because the lightings don't match.
