How Elain looks at Lucien :

“Her brown eyes were wary. Usually, that look was reserved for Lucien. The male was definitely in the family room.”

How Elain looks at Azriel :

“She looked up at him, her face so trusting and hopeful and open that he knew she had no idea that he had done unspeakable things that sullied his hands far beyond their scars.”

The difference and besides, isn’t the antonym of wary actually trusting? Interesting.
