I think Aurora is going to play a big part in the good vs evil here. She is trying to do good, but due to the fact that Cora has her heart, it is impossible for her to have that kind of free will. And Snow and Emma are going to ask themselves how Cora knew where they were going. I see no way that they are not going to be able to figure out the heart seen. Also I’m wondering about Precurse fairytale land, because even though the episode is called the queen of hearts, all we see is Regina and Hook. Maybe Hook learned the whole heart taking thing from Regina.
Also just pointing out Emma finally did get to punch someone in the face, hard. And it looked like it hurt
