Saga becomes curious about the people of her world. As he had sense from her that her world...she's running away from. While he doesn't think her world could be that bad...just different from his own. Vastly different. Every world is both good and evil.

"You are always safe here with me. However, if there's a chance that...there's anyone from your world come here and they meant us no good, then I'll devise a back-up plan. You just have to tell me when you sense danger."

As he had told her no matter how big or small, he is her husband and it's his duty to protect her. "I'm always on your side."
