The one magic concept could be broadened in order to explain how Lucy's mother knows the certain type of magic, but I don't think its Lucy's mom since Jellal was surprised, it is most likely someone that Jellal knows, which could still be in question I guess since it has been seven years. Who could it be?hmmm....
