Still hoping that Leopold is the father though. Cora and Leopold having a past affair (or just relationship), Zelena being the product and Cora just erasing Leo's mind and send Zelena to Oz so no one would ever find out about them.

And I kinda like it too because she also is trying to ruin Snow's life now. Hinting that she might know that Snow is her half-sister too, who also was important, but to her father instead.
