Obviously as any true friend, Jesper wishes that he never met Inej in the sense that he wishes she was safely with her family all this time, but selfishly for himself, he can't imagine a life without her. She definitely made all the rest of them better. They're a damaged group, the Crows, but the love they built is very real because of it.

"I thought they were supposed to be paragons of virtue. Better than the rest of us." Jesper genuinely doesn't know, he's not only teasing her, although he's teasing her a little. He doesn't have any problems with her faith, he actually knows all the names of her knives and the Saints she values, because he listens.

He knows how his mother would feel about Inej. No question. "You remind me of her sometimes. It's your positivity and optimism, she was an unwavering person that way." He doesn't know how Inej does it most of the time, but she has that lightness in her, despite all the darkness. And his mother was the same. Nothing could go so wrong that would put her off her belief in things being better.
