Once Upon a Time 4.7

We had an exciting Once Upon a Time episode. Using her magic, Emma captures the Snow Queen {with Belle's help} before the Snow Queen can unleash her mirror on the townspeople. But while interrogating the queen, Emma loses her focus and is pushed over the edge, causing her powers to unlock and become uncontrollable. The startled reactions from her family and Snow's sharply worded, "Emma!" don't help at all and Emma flees. Elsa can understand her and tries to reassure her family. Meanwhile, Robin Hood is in quite a pickle; he wants to save his wife because he sees that as the right and honorable thing to do, but he's deeply in love with Regina and can't give her up as she requests. All of this action is backed up with flashbacks into the Snow Queen's past wherein we meet the silly Duke of Weaseltown and find out why she was in the jar and so bitter.

The only plot problem I recall was that the memory spell wouldn't work on all the neighboring countries who would've heard all about the three beautiful princesses of Arendale.
