You shouldn't use the same "narrative device" all the time. It's cheap and lazy. A mystery is when some event happwns and you need to figure out what is going on, for instance Elsa coming to storybrooke and now there's a mystery of what happened to her and her sister and how is that crazy old ice cream lady involved.

Having Snow and Charming stealing a baby without any indication before the plot needed it is not a mystery, it's a plot hole. Having Hook lying about something else is not a mystery. It's just poor character development.
