When Deborah is picked up by Mike - The Realtor (played by Thomas Haden Church) and he backs his Audi out of the driveway, there is no license plate on the car. In the next shot, it suddenly has one.
When Flor and her daughter are moving out, the green dress she is wearing seems to go from wet to dry to wet again.
After Deborah ask the man washing cars in Malibu to translate for Flor and he pauses to put on a button up shirt before he translates, as he translates in one shot his shirt is askew because he has buttoned it wrong. In the next shot his shirt is buttoned correctly.
When Deborah and Cristina return from the flea market Deborah is holding a white chandelier in her right hand. In the next shot when Cristina hands the blanket to Deborah the chandelier is gone. Deborah never put the chandelier down or handed it off, it simply vanished.
When Flor is going up the stairs in the summer house after discussing with John with Cristina's help, and stops to continue talking to John, her hair changes from one shot to another.
After Deborah comes in from running, she is in a sports bra and bike shorts. When she climbs on top of John, you can clearly see that she still has her shorts on when they have sex.
As Cristina "blossoms" Flor needs to get only a day job, but her two jobs prior to that are at a travel agency and at a dry cleaners, both of which would have been during the day.
Flor consistently speaks with a Castilian accent, not a Mexican one.
