There is a strongly supported theory that Anastasia is Cinderella's step-sister. If this is true, then this episode takes place after The Price of Gold. It is also implied that this takes place before Snow Falls/Snow Drifts, since Robin is still stealing and not mourning over his dead wife. This is only based on assumptions, but I narrowed it down to a very specific place in the timeline.
