After coming to know the hard life she had lived, Zavier developed a strong sympathy for the unfortunate girl. He could see his own shadow in her, a life that lonely wasn't very worth living. He had already experienced it and he wanted to save her from it.
Her tragedy had invoked a protective instinct in him that made him want to shield her from all kinds of harm. It made him want to be the wall that kept her away from the fierce winds and the shelter that prevented her from getting wet in the rain.
Zavier looked at her with more and more tenderness like he wanted to give her all the good things in the world to make her realize that she was not alone and that she deserved to be happy as well. He wanted to tell her that her life could be more than some tragedy and a revenge story that she had to follow through to the end.
