In Storybrooke, David remains under the sleeping curse as Regina, Henry and Mr. Gold watch over him. Mr. Gold and Regina step away and he tells Regina in no uncertain terms that they can’t let Cora come to Storybrooke. His plan is to use magic on the portal where someone could come through to Storybrooke, killing whomever it is that comes through. Regina argues that she promised Henry she wouldn’t hurt Emma or Mary Margaret, and if they can defeat Cora and come through, she can’t be responsible for killing them. But Gold argues that the possibility of anyone but Cora coming through that portal is remote at best and if she wants to protect Henry, she’ll do this. She reluctantly agrees and the two of them steal magic from the fairy dust diamonds in the mines, using it to cast a glowing, green forcefield over the magic well in the woods outside of town.
