See, if Gideon is a Dark One, I wouldn't think of it as being genetic. I assume it would be because he was raised in the Dark Realm, which to me means that perhaps some of the Darkness exists there. He wouldn't be a Dark One by blodd, he would be one because he was exposed to it due to where he lived.

We know nothing of the Dark Realm other than it's where the Black Fairy lives, Gideon was raised, and it contains dark magic beyond Rumple's understaning. Who's to say he didn't become a Dark One through other means than we currently know of?
