I'd have to go back and check on that myself, regarding Merlin placing the Chernabog. Also, if I recall correctly, Merlin was brewing the curse (or a variant of it), which is what Nimue used to cast the curse using Merlin's heart. so that would be like the 4th time it was cast (Regina, Pan, Snow, and Merlin/Nimue/Hook). Maybe the setting of Storybrooke was set with the initial (Regina's) casting, and further castings simply use the previous setup?
