I am disappointed to learn that Agnes is likely playing Lilith. Horrible miscasting and disrespectful of the ethnicity of the child version of the character, whether or not the child actor was chosen to remind of us of Regina.
Last year when I was on a different board, I too had theorized that Lilith was the black fairy or a demon when she first appeared in OUAT…I actually said that maybe Lilith and the Blue Fairy came from the same ball, with Lilith being the dark husk and the the Blue Fairy representing the light (referencing the bible here). In Once, if they don’t do a ball of darkness and light, then I am pretty sure they have the same point of origin, and are maybe sisters/two sides of the same coin.
If not, then maybe she is Blue’s daughter after all, as someone else had said.
Keeper of Regina's bravery
