When Tiger Lily saw the Fiona turn into a fairy, she said "that's not possible" - possible indicating they were born that way. I assume Blue was originally a fairy and most fairies are born fairies. I see that it may be like Mermaids. Ariel sort of temporarily gave Snow her mermaid tail and I assume Snow was a mermaid for that brief period of time.

TL expressed that's impossible, so I assume Blue was keeping that spell secret and TL just accidentally brought all the books to Fiona.
