I have to say that for the first time, I was confused by the point of an episode. I mean, really, what is the point of this plot twist? Why the need for twins? Why have one son gone and another replacing him. But, I bet there is a reason that we will find out later on. I just found myself distracted at times because I was too busy wondering why we were being taken down this path.
However, knowing that new info keeps getting thrown at us, I imagine this will be vital later on.
I did enjoy Rumplestiltskin as usual, and the acting was terrific across the boards.
