Another great episode. So my far out theory was wrong unsurprisingly. Obviously, I'm no clairvoyant. However, I will make one prediction that I'm convinced will happen: Rumple will turn on the Black Fairy and save the day assuming he's truly on her side (which I'm not convinced of at this point). If that's the case, he won't turn but just do what he already had planned.
"Born on a winter's night to become the Savior." Instead of the Wise Men, we got Blue Fairy and fairy godmother Tiger Lily coming to visit the family.
It was quite ironic that Fiona's desire to save her baby Rumple from the prophecy turned her into the very darkness that she wanted to protected him from.
