First of all how do we know all of those bottles along with the one with Charming and Snow’s hairs are for the curse? Did he or any character say so? Do he say I bottles this stuff to make a curse? Did another character say he Rumple how’s that curse coming? It may be for the curse or not. Maybe those are just different potions. How did any of us conclude that those bottles are curse related? We do not really know. We also do not know why he acquired Snow and Charming’s hair for savior purpose either. Rumple said, “No two loves are alike.” and that he has never bottled a love potion. Who knows what his is going to do with those bottles. do we know for sure why he bottled the hairs? We also do not really know.
