When Nikki walks in to the kitchen for breakfast before school the plate is empty. When the scene changes the plate is wrapped in foil. When it switches back the plate is empty again. When Nikki leaves it is wrapped in foil again.
In the scene where Vanessa woke up alone in Frankie's house, after the initial confrontation, they are talking in the kitchen ? Frankie's hand changes from around the side of Vanessa's neck to under her chin and then back again around the side of her neck.
Frankie tells Vanessa that he brings his son to the park on Saturdays and would like to meet her there. It shows in another scene from that day that Nikki, the foster child, had been in school that day so it couldn't have been a weekend day.
