Anton said that Cora brought him to Storybrooke to grow some beans. What was her plan for the beans? As far as Anton mentioned, and I quote: "Whatever it is she planned on doing with them, it can't be good."
Does anyone know the answer?
Did Cora even know that Anton had the ability to Grow beans? I mean, all the magic beans had been destroyed, and there is no reason for anyone to suspect that Anton has a magically preserved bean clipping available to grow more.
As for what Cora would do, I think that is obvious. Cora wanted Power. She was, in many ways, just like Rumple. and having beans, if that was her goal, would just give her the opportunity to subjugate more worlds to her power. She already controlled much of Wonderland, and with Regina, she would have control of much of the EF as well. And while we didn't know it at the time, I would imagine that Cora would have made amends with Zelena, giving her Oz. Cora, as the Dark One, with Magic beans for traveling, would be a force to be reckoned with.
