My opinion is that it was juliette who looked like a monster so Juliette thought everyone would see her like that.
She was fed up with Nick, she also started to hate him and Nick was a common man,
Nick did not have any kind of mental power to know what was going through the mind of juliette-at the spice shop she blames them-,and juliette believing that Nick could kill her for being a ".HEXENBIEST".that shows that she did not trust him and did not really know him if he thought he could do something like that.
Juliette only read in the books
