Continuity mistake: When Joshua says that he won't send Naomi away because Collinwood is her home, the actor mispronounces the mansion's name as "Collingwood." Definitely not a character choice: Joshua, who founded the Collins family dynasty, would neither forget nor mispronounce the name of his own estate. (00:14:45)
