Was there any reason behind Marion/Zelena being frozen during the Snow Queen's reign? Did she know that she was Zelena? Was she afraid of her powers? Why did she not reveal to the rest that it was her?

On the other hand, why wasn't the all powerful Zelena able to break away from the freezing curse? Or at-least somehow slow it down to make it look less powerful but without revealing that she has magical powers?

EDIT after other people pointed out in the comments (and I agree) is that Marian being Zelena was a plot twist they came up with later on. Let's say that the Snow Queen attacked Marian and not Zelena. What is the reasoning behind this? What reason could she possibly have to attack Marian?
