Nesta Does Not Deserve This Hate - Tumblr Posts

In ACoWaR during the meeting of the High-Lords and during the War, Nesta felt the power of the Cauldron.

It effected her to the point of physical illness (probably mentally as well).

So when Feyre and Rhys destroyed the Cauldron to pieces, broke it's very essence - I am positive that Nesta FELT that as well, felt what is was like to be broken into pieces as if she herself was being torn apart.
