MEN hate crying more than anything else. That's why they rarely do it. However, it doesn't mean that they're not capable of feeling pain. When they do cry, it just means that they're too tired of acting strong or when they are so afraid of losing someone they love more than themselves.
And this is the first time someone bawls their eyes out upon seeing her. She's not sure exactly what to feel. Although Selene wonders, as she gently taps the Emperor's back while he sobs in her arms, who did he lose for him to act this way? Who did he see when he looks at her? He must have loved that someone so much that he let his guard down in front of a stranger. Selene's heart breaks with the thought. Somehow, she doesn't understand herself anymore.
