As it currently stands, we don’t know enough about the WW, her powers, or her curse to know whether there is magic or not in SB. I’m inclined to think that if/when the WW casts this new curse (as it seems she will), then I’d say initially there won’t be any magic in town, just as there wasn’t in S1 until Rumple dropped the potion of true love down the well. Maybe the WW will likewise try and bottle true love from the hairs of Charming and Snow; it seems like the second child of Snowing and the new baby for Aurora/Philip could also be important to the WW’s plans. Maybe she wants to make more saviors? I could see it going that way (which would be sort of unoriginal if you ask me, but hey, the writers will do what they will).
