In snow white the evil queen used spells and potion in order to age shift which also mean in my point of view that she can break her spells. where as mother gothal used the magical flower to become beautiful as her age shift is perminant and she must contain her youth with a chanting song. The dagger how ever is similar and i am guessing that they took insperation from the evil queen and created another charactor with it. Its like taking charactoristics from a harry potter charactor and creating a similar look alike but bend it how i want that charactor to be in my story!!!
