For me the Challia and Xavier pay off was more about Xavier finally finding his voice. He'd put up with so much bullshit throughout the series without batting an eye, but Challia acting suicidal was what made him snap and actually start crying. And his compassion ties back in to Challia's statement in the novel about having no one who cares for him - like with Machu with Shuji, he was able to bring the highlights back to his eyes.
