Some of Kat's recent posts on Tumblr have revealed something interesting: the Black Fairy will be casting a new curse in the climax of the season (possibly in 620, possibly in 621/622 ): the Black Curse. She hasn't elaborated a lot, but it appears to be the reason Emma is in an asylum in this picture, it's got some notable differences from the Dark Curse,  it may not require the heart of the thing she loves most (and if it does, it's probably not Tiger Lily or Blue ), and it definitely doesn't take Emma's memories (and possibly not Henry's).

I'm betting that this is why Fiona needs all of that dark fairy dust. We know from Roderick that she created the Dark Curse with dark fairy dust and he expressed fear in what she'll do with more. It could also be why she needed dark fairy crystals.

So what exactly will it do? And why doesn't it affect Emma and Henry? And where does the asylum come in??? Speculate away!
