As we all know, Nikolai's a determined, arrogant, sly bastard. He claimed,
“When people say impossible, they usually mean improbable.” in (S&S).
But here's a testament how he deems Zoya.
"He turned his head, trying to decipher the dark slash of her brows, the black of her hair. She looked just as she always had—beautiful, impossible Zoya." in (RoW),
With her unreal beauty, she cannot be swayed by anyone even by him, she's almost 'divine' in my own words. This, the only moment Nikolai claimed that there is something impossible for him, and Zoya is her name.
