I don’t think Emma is going to let them approach her easily, and I think that is going to cause conflict. They both are going to have a hard time bonding with Emma, who may not be able to right away seperate Snow White and Prince Charming from their Storybrooke counterparts. Henry will be the most willing–this has always been his dream. 😆 He’ll probably try to encourage Emma more, and that may be able to ease the tension. Henry was the one to bring Emma to Storybrooke, I think he will be the one to help connect the Charming family together. 🙂
Prince Charming is certainly going to hold Regina responsible. The fact that she hit on him is going to add fuel for his dislike of her–I wouldn’t be surprised if we see him going a bit on the vengeful side. Not too dark, but he will hold her also responsible for what happened to Snow White when she was Mary Margaret and how she was hurt, and that is something that I don’t think he will ever forgive. He may also have a hard time forgiving himself–he hurt Snow White. 🙁 Unintenionally, but she was hurt with no one (except for Emma) on her side and comforting her.
