Maybe the BF tried to create a spell to lead her to another world for some reason ( turned out to be the dark curse) and Tiger Lily ( possibly someone familiar to her, like her sister ?!?) knew this, than shared it with Blue -> Blue banished BF for doing dark magic. BF desperated abandoned her new born Rumple -> she got darken and believed all that light magic brought nothing good to her ( and others...) -> then decided to raise all the kids she found to be dark and strong ?
