Indeed and all that is part of my own hopes for CS magic as well, but again, not really to do with Layla having multiple keys. It could be connected to the "One Magic" which I assume is the reason Lucy survived Alegria and if that is the case, why only her? Could it be that having access to the One Magic comes with self-realization and nothing other than that? Though this might not be the case with Layla but who knows, maybe it is the first time in history for a mother and daughter to both be so in tune with the magic world. I have great hopes for this kind of development. It makes Lucy's magic of the exact same or more importance as Dragon Slayer magic not only for the Eclipse but FT universe in general and thus is a nod at Rave, which is all good. CS magic is definitely going to be of more importance in coming arcs.
